Authors: Inoue Akihiro , Nagao Michinobu , Yamamoto Atsushi , Sakai Reiko , Morita Satoru , Yoneyama Masami , Sakai Shuji
Published: November 2024

Motivation: In the Fontan circulation, congestive liver and lymphatic congestion caused by elevated central venous pressure become permanent. These complications (called as FALD) are considered poor prognostic factors as Fontan-associated liver disease, and hyperplasia of abnormal lymphatic pathway have often been seen. Goal(s): We attempt to depict abnormal lymphatic pathway using Gd-EOB-DTPA MRI and propose a classification of their severity. Approach: MR lymphangiography was scanned using three-dimensional heavily T2-weighted imaging with a 3-tesla scanner 10 minutes after Gd-EOB-DTPA administration. Patients were classified into the three grades. Results: MR lymphangiography with Gd-EOB-DTPA, demonstrates the localization and extent of the abnormal lymphatic pathways in Fontan circulation. Impact: In the Fontan circulation, the higer the lymphangiographic grade using MR lymphangiography with Gd-EOB-DTPA was, the more the adverse events was seen. The lymphangiographic grade is associated with the adverse events in Fontan-associated liver disease.

Authors: Ma Xiao , Seres Peter , Kinnaird Adam , Fung Chris , Wilman Alan , Beaulieu Christian
Published: November 2024

Motivation: T1 relaxation, T2 relaxation, mean diffusivity (MD) and volume can offer valuable information about prostate tissue remodeling that may occur with cancer and aging. Goal(s): These age relationships are relevant for identification of cancer thresholds, but also provide insight on unique prostate zone changes with age. Approach: 74 normal volunteers aged 19-69 years were scanned. Results: T1, T2, MD and volume in the peripheral zone showed a positive quadratic association with age being mainly flat and then increasing after 45 years. In contrast, there were no such T1/T2/MD versus age correlations in the transition zone, despite a marked increase of volume with aging. Impact: Quantitative T1/T2 relaxation and mean diffusivity demonstrate microstructural changes of the prostate, particularly in the peripheral zone and not the transition zone, with typical aging (19-69 years) which may provide a ‘normative’ benchmark for tumor identification.

Authors: Papageorgiou Ismini , Malich Ansgar , Rossknecht Lorenz , Hadjidemetriou Stathis
Published: November 2024

Motivation: Whole-body MRI, a screening tool for bone metastatic disease, uses parallel coil imaging to cover a large Field of View. Signal inhomogeneities at the coil junction points create jump discontinuities in the signal intensity with a negative effect on serial image stitching. Goal(s): To correct for signal jump discontinuities between coils using computer vision. Approach: We engaged piecewise smooth intensity nonuniformities fields using anisotropic diffusion and quantified for improvement in image entropy (H). Results: Our algorithm smoothens the signal intensity between parallel coils by 8% based on entropy metrics. Impact: We implement a novel non-parametric methodology with piecewise smoothness to improve intensity non-uniformities between parallel coil images in whole-body MRI (WB-MRI). Optimized whole-body stitched images render WB-MRI into a one-stop-shop staging method.

Published: November 2024

Motivation: Noninvasive and sensitive methods for assessing chronic liver disease-associated kidney injury are needed in clinics. Goal(s): We investigated the potential of arterial spin labeling (ASL) and blood oxygenation level-dependent (BOLD) MRI for diagnosing and evaluating chronic liver disease-associated kidney injury progression. Approach: We observed the renal blood flow (RBF) and T2* changes in rats with CCl4-induced chronic liver disease and compared imaging, pathological, and biochemical indicators at different time points. Results: During chronic liver disease development in rats, RBF and T2* gradually decreased, and ASL and BOLD MRI were more sensitive than serum creatinine in diagnosing renal injury. Impact: Compared with serum creatinine, ASL and BOLD MRI exhibited more sensitive diagnostic value for liver cirrhosis-associated renal injury, providing a noninvasive and reliable method for monitoring kidney injury in patients with chronic liver disease.
Time-dependent DW-MRS to probe lactate compartmentation in Huntington’s disease mouse model
Authors: Mougel Eloïse , Palombo Marco , Valette Julien
Published: November 2024

Motivation: In the healthy brain, lactate compartmentation and exchange are crucial for neurotransmission. In Huntington’s disease (HD), lactate metabolism appears to be impaired, but lactate compartmentation is unkown. Goal(s): To assess lactate compartmentation between intracellular and extracellular spaces under pathological conditions in vivo. Approach: Using time-dependent DW-MRS, which may probe lactate exchange and compartmentation, we measured diffusivity and kurtosis in a cohort of zQ175 mice, a model of HD, versus control mice at 3, 6 and 12 months. Results: Results suggest a larger extracellular fraction in zQ175 mice at 12 months, while no other microstructural changes would be measurable using DW-MRS. Impact: DW-MRS allows probing brain lactate compartmentation, thus unravelling some crucial aspect of lactate metabolism. Results suggest that, while no microstructural alteration can be observed in the zQ175 mouse model of Huntington’s disease, impaired lactate compartmentation is detected with DW-MRS.

Authors: Leserri Simona , Aydogan Dogu
Published: November 2024

Motivation: The currently available tools to describe changes in structural connectivity preclude an in-depth topography study of the brain’s white matter. We sought to quantify the degree of change in structural connectivity through the mathematical notion of directional derivatives. Goal(s): To define and compute the directional derivatives of tractograms. Approach: We defined a measure of connectivity at a point in the brain, that is expressed on the brain's surface. By using numerical differentiation, we computed directional derivatives of connectivity. Results: Our directional derivative method allows a comprehensive topographic study of the brain and highlights potential topographic patterns in structural organization. Impact: Directional derivatives quantify connectivity changes, enabling systematic topographic study of the brain. The computational neuroimaging tool developed may aid in neurosurgical planning, precise brain stimulation, and biomarkers identification. This versatility may contribute significantly to both neuroscience research and clinical practice.

Authors: Tung Yi-Hang , Mattern Hendrik , Speck Oliver
Published: November 2024

Motivation: Probing brain microstructure with high-b-value brain diffusion imaging was mainly performed at 3T. At higher field strength, the long echo times prohibited a significant SNR boost over 3T. At 7T, a high-performance gradient allows much shorter echo times and harvesting of the field-related signal gain. Goal(s): Determine SNR and explore feasibility of high b-value DWI. Approach: The SNR was measured in high b-value DWI at whole-body and high-performance 7T scanners. Results: The SNR improvement on the high-performance 7T is 2.76 ±0.12 and 1.73 ±0.05 compared to the whole-body 7T and high-performance Connectome 3T respectively, allowing even higher spatial resolution and higher b-value imaging. Impact: The shortcoming of 7T for high b-value diffusion MRI can be overcome when leveraging a high-performance gradient system, effectively reducing scan time 7.6-fold compared to a whole-body 7T scanner. This enables the next generation of diffusion imaging.

Authors: Zhou Jianan , Hou Zujun , Zhu Zhengyang , Tian Chuanshuai , Zhang Bing , Zhang Xin
Published: November 2024

Motivation: It is challenging to differentiate recurrent tumor from treatment response in glioblastoma. Goal(s): This study explored the issue using an advanced tracer kinetic model. Approach: Glioblastoma patients were examined using dynamic contrast-enhanced MRI and stratified into recurrent and treatment-related group based on histopathological results. Imaging data were analyzed using distributed parameter model. Results: Blood flow in lesion was significantly higher and permeability in peritumoral edema was significantly smaller in recurrent than in treatment-related group (p=0.002, 0.023). Combining two parameters together, diagnostic performance was attained at AUC (area under ROC curve) 0.93. AUC of extended-Tofts model was 0.89. Impact: With separate account of blood flow and vessel-wall permeability, advanced tracer kinetic model allowed more precise modeling the feature of tissue microenvironment, which could shed light on the difference between recurrent tumor and treatment-related response in glioblastoma.

Published: November 2024

Age prediction is an important part of medical assessments and research. It can aid in detecting diseases as well as abnormal ageing by highlighting potential discrepancies between chronological and biological age. To improve understanding of age-related changes in various body parts, we investigate the ageing of the human body on a large scale by using whole-body 3D images. We utilise the Grad-CAM method to determine the body areas most predictive of a person’s age. In order to expand our analysis beyond individual subjects, we employ registration techniques to generate population-wide importance maps that show the most predictive areas in the body for a whole cohort of subjects. We show that the investigation of the full 3D volume of the whole body and the population-wide analysis can give important insights into which body parts play the most important roles in predicting a person’s age. Our findings reveal three primary areas of interest: the spine, the autochthonous back muscles, and the cardiac region, which exhibits the highest importance. Finally, we investigate differences between subjects that show accelerated and decelerated ageing.

Japanese elementary schools introduced programming education in 2020, but are Japanese educators better equipped to teach this new subject? Most programming education research focuses on children. Unfortunately, educators are often overlooked. In this research, elementary schools in five Japanese prefectures were visited to understand better in-service educators’ tasks and preparedness in teaching programming. An electronic survey was distributed to twenty-five schools, augmented by interviews with school principals. Data shows that while educators are recently better equipped to teach programming education compared to 2020, much work remains to be done in offering teachers pre-service training and lifelong learning opportunities. This paper provides insight into better professional development for Japanese elementary educators in programming education.

Penulisan jurnal ini menggunakan metode penelitian hukum normative, yaitu dengan menemukan suatu aturan hukum, prinsip-prinsip hukum, maupun doktrin - doktrin hukum guna menjawab isu hukum yang dihadapi. Hasil dari penelitian ini menjelaskan bahwa dilihat dari Sudut Pandang Keperdataan, kasus ini masuk ke dalam Wanprestasi dengan mengacu pada permasalahan Surat Perjanjian Kredit jenis Cashcolleteral antara BRI Cabang Pekayon dengan Terdakwa. Tetapi pihak korban mengajukan tuntutan pidana karena ia merasa dirugikan oleh terdakwa karena melakukan pembukaan blokir dan menggunakan uang hasil kejahatan tersebut sehingga kasus ini masuk kedalam Tindak Pidana Turut Serta. Akibatnya, pihak Bank BRI belum mendapatkan ganti rugi yang seharusnya didapat karena Jaksa Penuntut Umum tidak Pemodal sebagai Tersangka dalam proses penyidikan dan tidak melakukan penyitaan terhadap barang bukti hasil pembukaan blokir di Bank BRI sedangkan alat bukti sudah ada berupa bukti transfer uang. Pernyataan diatas membuktikan bahwa Jaksa Penuntut Umum kurang teliti dalam melakukan proses penyidikan sehingga barang bukti sebagai ganti rugi Bank BRI tidak ikut disita sedangkan alat buktinya ada.
