Background: Noise is a fluctuation in the value of CT number and Standard Deviation which is one parameter in the assessment of CT Scan image quality. This study aims to see the effect of changes in the angle of the gantry on noise and conformity with the BAPETEN standard of the value of the CT Number and Standard Deviation fluctuations produced.
Methods: This type of research is quantitative with an experimental approach. The research subjects used water phantom to assess the value of CT Number and Standard Deviation by placing ROI on the resulting image. The SPSS test is used to see the relationship between changes in noise and noise. CT Number, Uniformity and Noise Uniformity tests are performed to assess CT Number and Standard Deviation in accordance with BAPETEN regulations.
Results: An increase in noise is indicated by fluctuations in the value of CT Number and Standard Deviation resulting from the placement of the ROI at the center of each image produced by each change in the angle of the gantry. The average value of CT Number at the gantry angle 00 (-1.43), 50 (-1.48), 100 (-1.47), 150 (-1.58), 200 (-1.62), 250 (-1.68), 300 (-1.7). The average value of the Standard Deviation at the 00 gantry angle (2.36), 50 (2.35), 100 (2,3), 150 (2,33), 200 (2,42), 250 (2,57), 300 (2.62). There is a significant relationship to the Pearson correlation test between changes in gantry angle and CT Number and Standard Deviation values. CT Number, Uniformity, and Noise Uniformity Test results were used to assess the fluctuations of CT Number and Standard Deviation due to changes in the angle of the gantry in accordance with the standard BAPETEN No. 2 of 2018 on all changes in the 00 gantry angle to -300 with a range of 50.
Conclution:. Noise fluctuations are caused by changes in the thickness of the scanning area object from changes in the gantry angle. The greater the change in angle of the gantry, the greater the thickness of the scanning area object. Changing the gantry angle causes the scanning area to change from the circle to the ellipse.

ABSTRACT
Thorax examination involves the projection of Posterior Anterior, Posterior Anterior and Lateral Anterior. When doing a thorax examinationin a standing position, the object must face the bucky PA or Lateral projection stand. The study aims to determine the difference between density and thorax radiograph contrast using a grid and without a grid. The study employed quantitative descriptive method. The results show that radiographs using grids had a low density and high contrast due to the grid function which absorbed scattered radiation coming out of X-ray tubes, so that the image could distinguish between soft tissue, bone and mediastinum. Whereas on a no-grid radiograph, it had high density and contrast because all the radiation coming out of the X-ray tube was absorbed by the image receptor, therefore the resulting image was too black and not optimal in distinguishing soft tissue, bone and mediastinum. In examining the thorax, it will be more optimal by using a grid, but it can also be regulated by exposure factors.

Background: Herlyn-Werner-Wunderlich syndrome (HWW) is a very rare genetic syndrome, a combination of anomalies between the mullerian and mesonephric ducts characterized by uterine didelphys, hemivaginal obstruction, and ipsilateral renal agenesis, also known as Obstructed Hemivaginal syndrome and Ipsilateral Renal Anomaly (OHVIRA). Magnetic Resonance Imaging (MRI) is an effective diagnostic support tool for finding out anatomical abdominal abnormalities with the right choice of protocol sequences to obtain optimal MRI images.
Method: This study used a qualitative descriptive approach by presenting a case of a 20 year old female patient who had complaints of lower abdominal pain, no previous medical history and irregular menstruation. MRI Abdomen without contrast was performed using an MRI 1.5 Tesla signa explorer GE Healthcare at EMC Tangerang Hospital. Using the Coronal T2 SSFSE sequence, T1 fat sat LAVA, Axial T2 SSFSE, T1 fat sat LAVA breath hold method and Coronal 3D IFIR (MRA renal without contrast). Specifically for the pelvic area with the Axial T2 Propeller, Coronal T2 fat sat, and Sagittal T2 sequences.
Result: In the Axial T2 propeller sequence, pelvic area retrieval revealed two separate uterine corpuses (uterus didelphys) accompanied by a heterogeneous oval lesion most likely originating from the left side of the vagina (hemivagina). Whereas in the Coronal T2 sequence the whole abdomen was taken and confirmed by the Coronal 3D IFIR, the right kidney was anatomically visible while the left kidney was not visible (agenesis).
Conclusion: Abdominal MRI is a very accurate diagnostic tool to perform Herlyn-Werner-Wunderlich (HWW) syndrome without contrast agent with SSFSE T2 sequences, T2 propeller and 3D IFIR which have an important role in visualizing the quality of MRI images.

Published: February 2022

Background : According to the theory, Neck MSCT examination were performed using monophasic injection techniques. Split-bolus is an innovative technique that divides intravenous (IV) contrast media into two or three boluses and combines phase images in single scanning. The MSCT split-bolus scan with a combination of parenchymal and vascular enhancement is a valid alternative approach compared to the standard monophasic MSCT protocol. The purpose of this study was to determine the split-bolus technique in neck MSCT examination and its role in the quality of the image.
Method : This research is a descriptive qualitative study with a literature review study method. Data is collected by the documentation method. The electronic database was searched using the keywords "head and neck" AND ("contrast" OR "injection") AND ("Split bolus" OR "Biphasic Contrast" OR "Dual bolus" OR "Double bolus" OR "Multi-phase" OR "Quadruple-Phase"). The inclusion criteria used were a research article on a split-bolus technique in a single scan on MSCT neck examination. Three articles met the inclusion criteria. Data analysis was performed using the annotated bibliography method.
Result : The results of this study indicate that the contrast media used in the MSCT examination of the neck with a split-bolus technique are non-ionic iodine contrast media with a total volume of 80-100 mL and a concentration of 300-370 mg / mL. Contrast media injection is done by dividing contrast media in the first and second boluses using a ratio of 3 : 2 or 1 : 1 of the total volume of contrast media followed by saline injection. The flow rate used is 2 - 3 mL / s with a fixed delay time between 70 - 120 seconds. The split - bolus techniques have a role in contrast resolution of image quality. The image quality produced on neck MSCT examination using split bolus technique can increase vaskular and tumor enhancement without reducing parenchymal enhancement and lesions. In a patient with metastasis, this technique can reduce artifacts due to excessive contrast media in the arteries and veins so the lymph nodes appear more clearly.
Conclusion : Based on the result, the split - bolus techniques have a role in contrast resolution of image quality.

Published: February 2022

Background: The different thickness of the thoracic vertebrae between the top and bottom causes the radiograph to have uneven density. The use of heel effect anode in the examination of the thoracal vertebrae of the AP projection has not been able to even out the radiograph density, so it is necessary to use a tool in the form of a wedge filter. This study aims to find the correct angle of inclination of the wedge filter to produce a radiograph with a sufficiently even density between the top and bottom of the AP projection thoracic vertebrae. The wedge filter tested tilt angle of 7 °, 10 ° and 15 °.
Methods: The research used quantitative methods, conducted from January to May 2018. The sample consisted of 4 volunteers and 10 radiographers as respondents.
Results: The results showed that the examination of the thoracal vertebrae of the AP projection without using a filter obtained an average value of 2.50 from the respondents, while using a wedge filter with a tilt angle of 7 ° got a value of 2.80, with a tilt angle of 10 º got a value of 3.43 and with an angle of inclination. 15 º gets a score of 2.93, so it can be denied that the use of a wedge filter with an angle of 10º is able to produce a more even radiograph density between the top and bottom of the AP projection spine.
Conclusions : To produce a more even radiograph density between the top and bottom of the thoracal vertebrae, the AP projection can be done using a wedge filter with an angle of 10°.
