Acoustic Frequency Minimization of Gradient Waveforms with GrOpt
Authors: Loecher Michael , Ennis Daniel
Published: August 2023

In this work, we measured the acoustic frequency response function of an MRI scanner. The response was then used to design arbitrarily shaped gradient waveforms that minimize the predicted acoustic noise output of the sequence. Two minimization functions were tested and compared to the conventional sequence with two different slew rates. The method was used to generate a GRE sequence with 31% reduced acoustic output for a 17% increase in scan time or 16% reduced acoustic output compared to the slew rate derated sequence, both with no difference in image quality.
Learned 3D radial trajectories using Image Quality Metrics from Prior Data
Authors: Tang Chenwei , Eisenmenger Laura , Kecskemeti Steven , Johnson Kevin
Published: August 2023

3D radial sampling provides high levels of acceleration with insensitivity to motion. Methods of designing the radial projection angles and orders have been focused on improving the sampling uniformity, which is indirectly related to image quality. We propose a flexible framework to optimize the sampling directly based on image reconstruction metrics. We demonstrated the optimized trajectories were able to produce higher quality images in both simulations and scans.
Motion-Resolved 4D Radial Ultrashort Echo Time (UTE) Lung MRI with Built-in Camera-Based Respiratory Motion Sensing
Authors: Wu Can , Krishnamoorthy Guruprasad , Subashi Ergys , Yu Victoria , Otazo Ricardo
Published: August 2023

Camera-based respiratory motion sensing (VitalEye) was successfully used to compute a respiratory signal for motion-resolved 4D radial ultrashort echo time (UTE) lung MRI. k-space data were sorted with respect the respiratory signal and binned into 10 different motion states to resolve respiratory motion. The respiratory signals from VitalEye were comparable to self-navigators. The 4D lung MRI reconstructions from both VitalEye and self-navigators were able to resolve respiratory motion and the signal intensity profiles along with the lung-liver interface and pulmonary vessels demonstrated that they both provided sharper image contrast compared to the motion-averaged images.
Streak reduction in radial imaging with CACTUS
Authors: Fu Zhiyang , Johnson Kevin , Bilgin Ali , Altbach Maria
Published: August 2023

Radial trajectories are appealing for efficient parameter mapping due to their robustness to undersampling compared to Cartesian trajectories. However, streaks due to scanner imperfections can significantly affect image quality and accuracy of parameter maps. Previously, we developed a streak reduction technique named CACTUS. CACTUS was demonstrated in cross-sectional (axial) abdominal parameter imaging. The other two imaging planes (coronal and sagittal) in radial MRI are more vulnerable to these anomaly streaks. In this work, we demonstrate the benefits of CACTUS in all three imaging orientations and investigate the effect of undersampling on the presence of streaks and associated parameter maps.

Authors: Wang Dinghui , Chao Tzu-Cheng , Baffour Francis , Krishnamoorthy Guruprasad , Pipe James
Published: August 2023

Spiral spin-echo and dual spin-echo sequences have been implemented for knee imaging at 1.5T with in-plane resolution of 0.51 by 0.51 mm2. High-quality proton density-weighted, T2-weighted and T1-weighted water and fat images at various orientations can be obtained using spiral Dixon imaging with comparable total scan time as the conventional Cartesian fast (turbo) spin-echo sequences without Dixon. Spiral T2-weighted water images demonstrated better fat suppression and a 24-67% increase of signal-to-noise ratio compared to fat-suppressed Cartesian reference images.

Authors: Stockmann Jason , de Lara Lucia Navarro , Daneshzand Mohammed , Meng Qinglei , Liao Congyu , Lee Hong-Hsi , Wald Lawrence , Bilgic Berkin , Huang Susie , Nummenmaa Aapo
Published: August 2023

We show that multi-channel TMS (mTMS) probe arrays can be used to generate B-fields inside the head for spatial encoding in concurrent TMS/MRI studies. We assess the field-synthesis capability of a 48-ch mTMS array for diffusion imaging and spatial encoding more broadly. Proof-of-concept diffusion imaging experiments on a 3T scanner using a 3-axis TMS probe achieve spatially-varying b-values >500 s/mm2 at the depth of the peripheral gray matter using only 4A of current. We consider the potential for scaling up to 200A for studies of gray matter microstructure.
A Proposed Method for Retuning an RF Coil by Changing the Shield Radius for Multinuclear Imaging
Authors: Davieau Kieffer , Fox Matthew , Chronik Blaine , Ouriadov Alexei
Published: August 2023

This study investigates the feasibility of changing the shield radius of an RF coil to shift the resonant frequency from 1H to 19F for multinuclear imaging. The method proposed in this investigation was verified by changing the resonant frequency of a 129Xe RF Coil a total of 1.18 MHz by changing the shield radius, allowing it to be used in a 2.9T Siemens MRI and a 3.0T GE MRI. It was found that altering the shield radius had similar effects on the resonant frequency as using a variable tuning capacitor, allowing for one coil to be compatible with multiple scanners.
A Truncated Twisted Solenoid RF Phase Gradient Transmit Coil for TRASE MRI
Authors: Sedlock Christopher , Purchase Aaron , Tomanek Boguslaw , Sharp Jonathan
Published: August 2023

TRASE is an MR imaging sequence that achieves k-space encoding through the use of phase gradients in the RF transmit field. The twisted solenoid is the most efficient RF transmit coil used for TRASE encoding; however, the geometry results in a long coil with a relatively short imaging volume. We introduce a new truncated design for the twisted solenoid to increase the usable imaging volume relative to the coil’s size. Simulation studies conducted indicate the truncated design can create similar imaging volumes to the untruncated version whilst significantly reducing the coils length by as much as a half.
Distortion Measurements Using a Large-volume, Lightweight, Modular MRI Phantom With Solid Signal Sources
Authors: Gardiner Mariko , Wachowicz Keith , De Zanche Nicola
Published: August 2023

Phantoms that cover large volumes are required to characterize geometrical distortion for image-guided interventions such as MR-guided radiation therapy (linac-MR). Liquid-filled phantoms of appropriate size can, however, be impractically heavy. Our phantom uses silicone rubber spheres arranged on a three-dimensional grid, resulting in a lightweight, portable structure. Displacements of each bead relative to the known grid positions are calculated in Matlab or 3D Slicer from 3D bSSFP scans. Design files and image processing code are available online.
Iterative decomposition of water and fat with echo asymmetry and least-squares estimation (IDEAL-IQ) for evaluation of early bone mass changes in senile osteoporosis patients
Authors: Yang Yonggui , Wu Xiufen , Chen Fang , Xu Xinyu , Wu Pu-Yeh , Yan Gen
Published: August 2023

BMD is the basis of the diagnostic criteria of OP recommended byWHO. However, limitations in the prediction and evaluation of fracture in postmenopausal_women, because BMD can not fully reflect the bone quality that affects bone strength and fracture risk. We found significant differences in the values among three groups. FF, fat-phase and water-phase value had good performance, while R2*value had poor performance in discriminating osteopenia and OPgroups. Overall, IDEAL-IQtechniqueis expected to provide certain reference indexes, which can noninvasively and quantitatively evaluate the bone metabolism of lumbar vertebrae, such as fat content, and provide accurate information for differential diagnosis of OP.

Authors: Samuels Petronella , Kraus Sarah , Cirota Jacqueline , Jermy Stephen , Moosa Sulaiman , Ntusi Ntobeko
Published: August 2023

Peripartum cardiomyopathy (PPCM) is a form of heart failure associated with pregnancy.1,2 We evaluated cardiovascular magnetic resonance (CMR) scans on 6 patients with PPCM and incomplete recovery. CMR showed an increase in left ventricular volumes and impairment of left ventricular ejection fraction (6-39%) in all patients. Right ventricular dysfunction was present in 5 patients. Linear mid-wall late gadolinium enhancement was present in all cases. Two patients had PPCM, one had dilated cardiomyopathy (DCM) with hypertrophy, 2 had DCM with left ventricular non-compaction [>6 months postpartum], and one had familial DCM. CMR is useful in distinguishing PPCM from other DCM phenotypes.

Published: August 2023

EPIMix is a multi-contrast EPI sequence developed which generates the standard brain imaging contrasts in 78 seconds. Studies using accelerated brain protocols like EPIMix and GoBrain have shown similar diagnostic performance to the routine clinical protocols. However, EPIMix suffers from EPI geometric distortions and like GoBrain is limited to 2D acquisitions. EPIc-reMIX, an accelerated brain imaging protocol, was created to leverage the speed of EPIMix and GoBrain while improving image quality and adding 3D-imaging capabilities.

Authors: Takatsu Yasuo , Nakamura Masafumi , Sagawa Hajime , Suzuki Yuichi , Mori Nobuyuki , Motegi Shunichi , Miyati Tosiaki
Published: August 2023

We performed echo planar imaging (EPI) and turbo spin echo (TSE) diffusion-weighted imaging (DWI) using magnetic resonance imaging to obtain basic clinical data of the apparent diffusion coefficient (ADC) in 26 parts of normal brains and compared the datasets using our retrospective distortion correction technique. The ADC was significantly higher measured by EPI-DWI than by TSE-DWI. The signal-to-noise ratio of EPI-DWI was significantly higher than that of the TSE-DWI. Care must be taken when measuring ADCs near the base of the skull, such as the brain stem, where the SNR of the imaging technique is likely to decrease or distort.

Utilizing a cross-sectional survey, 529 respondents answered items regarding symptom prevalence and its attribution, acoustic noise at work, health factors and work-environmental details including stress. Respondents were categorized into three groups (MR personnel, CT personnel, and mixed personnel (both MR and CT)) and data were tested with logistic regression to evaluate risk associations with symptoms.
Reducing MRI scan time to increase patient throughput
Authors: DeVincent Craig , Srivastava Madhur , Mendoza Armando
Published: August 2023

We have developed a novel wavelet-based signal processing algorithm capable of denoising signals with extremely low signal-to-noise ratios. The idea is that if raw MRI signals can be denoised in real-time prior to image generation, high quality images can potentially be obtained at drastically shorter scan-times, thereby improving patient comfort and increasing imaging throughput. While conventional signal processing methods are often limited by inadequate noise removal or signal distortion, our method does not suffer from such drawbacks, as it performs localized noise removal based on capturing randomness. This represents an opportunity to increase MRI throughput within existing infrastructure.

El Hospital de Antequera y la Orden Hospitalaria de San Juan de Dios (1673-1820)
Authors: Berrocal Tomé Francisco Javier
Published: August 2023

Objetivo principal: realizar un acercamiento a la asistencia sanitaria prestada por la Orden Hospitalaria de San Juan de Dios (OH) en el Hospital de Antequera tras el fracaso de la reunificación hospitalaria del siglo XVII. Metodología: Se han utilizado diversas fuentes documentales principalmente procedentes del Archivo Histórico Municipal de Antequera, así como de libros y literatura científica relacionada con nuestro tema. Resultados principales: El prestigio que los hospitalarios iban adquiriendo en Andalucía propició que las autoridades municipales dejasen en sus manos la dirección del hospital que estaría a su cargo desde 1673 hasta el procedimiento de exclaustración de inicios del siglo XIX. Se describen las reglas de los hospitalarios que abarcaban aspectos tanto religiosos como sobre atención hospitalaria, recogida esta última en diversos libros de registro. Conclusión principal:  La OH se presentó en un principio como la solución para el buen funcionamiento del hospital antequerano. Sin embargo, su gestión siempre fue muy criticada desde ciertos sectores. En su expulsión, a principios del siglo XIX, influyeron las tensiones y conflictos con los que se inició el siglo XIX.

THE EFFECT OF QUERCETIN ON SOME HEMATOLOGICAL PARAMETERS AGAINST BISPHENOL-A EXPOSURE IN STREPTOZOCIN-INDUCED RATS
Authors: KOÇAK Yılmaz , OTO Gokhan , ALPARSLAN Seray
Published: August 2023

Bisphenol-A (BPA) is an endocrine-disrupting environmental toxin widely used in the composition of plastics. Today, the widespread use of BPA in preserving and packaging food and beverages increases BPA exposure. Therefore, recent research has focused on the health effects of continuous exposure to BPA. This study aimed to investigate the protective effect of quercetin (QUE) on different hematologic variables in rats induced by the environmental toxin BPA and streptozocin (STZ). Wistar albino rats were administered BPA orally (p.o.) at 10 mg/kg and QUE intraperitoneally (i.p.) at 15 mg/kg for 14 days. STZ was administered subcutaneously (s.c.) in a single dose of 50 mg/kg at the beginning of the experiment. 72 rats were randomly selected for the experimental procedure and divided into 9 groups with 8 animals in each group. The groups were created as follows; Group 1: Control (Saline); Group 2: Corn oil (0.5 ml, solvent); Group 3: STZ (50 mg/kg); Group 4: BPA (10 mg/kg); Group 5: QUE (15mg/kg); Group 6: STZ (50 mg/kg) + QUE (15mg/kg); Group 7: BPA (10 mg/kg) + QUE (15mg/kg); Group 8: STZ (50 mg/kg) + BPA group (10 mg/kg); Group 9: STZ (50 mg/kg) + BPA (10 mg/kg) + QUE (15mg/kg). STZ and BPA-treated rats showed functional variability in all hematologic parameters. The combination of STZ and BPA significantly reduced erythrocytes, leukocytes, and their associated parameters. However, QUE treatment alone or in combination corrected the altered hematologic parameters. The results of this study demonstrated that exposure to BPA in combination with STZ may alter hematologic indices, while QUE may be a therapeutic agent to correct the altered blood profile.

This paper consists of an analysis of criminal offenses against road traffic safety, as follows: Endangering public traffic Art. 289. CC, Endangering traffic by dangerous action and dangerous means, Art. 290. CC, Negligent exercise of supervision over public traffic, Art. 295. CC and Failure to provide assistance to a person injured in a traffic accident, Art. 296. CC and it is all performed through a theoretical approach and analysis of court practice. In the introduction, we pointed out the methodology of research and analysis of traffic accidents and their consequences. The second part of the paper refers to the theoretical approach, the analysis of criminal offenses against road traffic safety in the criminal legislation of the Republic of Serbia. The third part, the empirical part, includes three levels of research over a seven-year period. The first empirical part refers to reports, lawsuits and convictions for criminal offenses against road traffic safety in the territory of the Republic of Serbia, in a seven-year period (from 2015 to 2021). The results of the research performed in this part of this paper indicate extremely mild sentences imposed on the perpetrators of crimes against road traffic safety, among which suspended sentences dominate, while mild prison sentences were imposed in only 7,87% of cases. The second empirical part includes the analysis of traffic accidents and their consequences in relation to dead persons, lightly and seriously injured persons, as well as other traffic accidents that resulted only in material damage in a seven-year period (from 2015 to 2021). The purpose of this part of the research is important for monitoring the dynamics of the volume and movement of both traffic accidents and their consequences. Participants in traffic accidents, that is, drivers, passengers, pedestrians, cyclists, trucks, buses, were the subject of the third part of the research. This part of the research shows that drivers and passengers in passenger vehicles are the most vulnerable category, considering that among them are the most people killed in traffic accidents. In the concluding remarks, as a result of the research and analysis of traffic accidents and their consequences, we pointed out the necessary amendments and changes of the de lege ferenda incriminations of criminal acts against road traffic safety in the Criminal Code of the Republic of Serbia.

Objetivo: Determinar los microorganismos presentes en el cultivo intra-operatorio de secreción periapendicular pre y post disección relacionados a la técnica quirúrgica en apendicitis aguda no complicada en pacientes atendidos en el Hospital Nacional Dos de Mayo. Material y métodos: Estudio de tipo analítico, longitudinal, observacional y prospectivo, 102 pacientes con apendicitis aguda no complicada mayores de 18 años, lo que hace una muestra de 204 cultivos de líquido periapendicular que fue tomado en dos tiempos quirúrgicos (pre y post disección apendicular), con dos técnicas quirúrgicas (abierta y laparoscópica) recolectados entre los años 2019 y 2020. Resultados: Los pacientes en su mayoría fueron de sexo masculino con un 54,9% con edad promedio de 31 años (DE:11,39), el 30,4% de pacientes tuvieron patologías que pudieron afectar los resultados del cultivo (Diabetes mellitus, TBC, VIH); el 51% tuvieron un diagnóstico post-operatorio de Apendicitis aguda congestiva y el 60,8% fueron cirugías abiertas. Los microorganismos más frecuentes en el líquido periapendicular pre-disección fueron la Escherichia coli con un 31,4% y Bacteroides fragilis con un 25,5%; y de la post- disección fueron la Escherichia coli y Klebsiella spp. con 44,1% y 39,2% respectivamente. Según la prueba estadística de Chi cuadrado si hay una relación significativa entre técnica quirúrgica y la presencia de Escherichia Coli (p=0.003), Pseudomona aeruginosa (p=0.002), Klebsiella spp (p=0.009) y Bacteroides fragilis (p=0.007). Conclusiones: Los microorganismos aislados en su mayoría fueron bacterias anaerobias gram negativas, por lo que se debería priorizar el uso de antibióticos que ataquen la especie mencionada en la fase no complicada de la patología, por haber relación entre microorganismos y técnica quirúrgica se recomienda ahondar en el estudio de esta patología de acuerdo a los cultivos post disección apendicular según acto quirúrgico a realizar.
