Background: Thick Slab is a technique used in the MRCP examination to acquire the image of the biliary system by using oblique slices in taking some parts of the image at different angles. Image quality with a thick slab technique is considered better than the thin slice since the image visualization of the bile ducts system in various parts appear more clearly. Aims: The purpose of this study is to determine the effect of variation in the number of thick slab on the scan time and image information on the MRCP and determine the most informative image with the most effective scan time as possible. Methods: This study type was an experimental study conducted in St. Elisabeth hospital Semarang. The data were in the form of 90 MRI images of biliary tract of 3 patients with 5 variations of Thick Slab (6, 12, 18, 24, 30). The image assessment was taken by 5 respondents regarding the information of the objects of Right Hepatic Duct, Left Hepatic Duct, Common Hepatic Duct, Pancreatic Duct, Cystic Duct, Common Bile Duct and Gallbladder. Data analysis was conducted by regression test and cross tabulation. Results: The study results showed that there was an effect of varying the amount of thick slab on the scan time. The effect of varying the amount of thick slab on the image information can be seen from the statistical test that there was no effect, however descriptively there was a different on the specific per object. The image of thick slab variation of 12 was an image that had the highest value of information with the mean value of 1,988, the total value of 13.936 and a scan time of 0.46 S so that the most informative image with the most effective scan time was on the thick slab number variation of 12. Conclusion: There was an effect of variation in the number of thick slab on the scan time. More variation of the number of thick slab was followed by an increase in the value of the scan time. But there was no effect of variation in the number of thick slab on the image information, however descriptively there was a different on the specific per object which showed that the highest score for the Right Hepatic Duct, Common Hepatic Duct were in the thick slab of 12 and 30, respectivelyÂ

Background : Signal to Noise Ratio (SNR) is a comparison of the magnitude of the signal amplitude and the magnitude of the amplitude of noise an MRI image that can be used to measure the quality of an MRI image. SNR can be increased by increasing the value of the number scan average (NSA). By increasing the NSA, the SNR will also increase, the scan time will be longer and cause motion artifacts. The purpose of this study was to determine the effect of using the parameter Number Scan Average on the Signal to Noise Ratio and Scan Time on examinations using Magnetic Resonance Imaging modalities. Methods: This study uses a descriptive qualitative method with a study approach literature review regarding the effect of using the parameter Number Scan Average on the Signal to Noise Ratio and Scan Time in the examination using Magnetic Resonance Imaging modalities. Results: The use of variations in NSA values has an effect on SNR and scan time. Giving high value of the NSA will increase the value of the SNR in the image but, the scan time will be longer which affects the quality of the resulting image.

MRI of the shoulder joint is a radiologic examination to evaluate internal abnormalities of the shoulder joint. The purpose of this study was to determine whether there is a difference in anatomical information using proton density fat saturation sequences and short tau inversion recovery and to determine which anatomical information is better between PD fat saturation sequences and short tau inversion recovery coronal pieces of MRI examination of the shoulder joint with rotator cuff tear cases. This research method is quantitative experiment. The results of the Friedman test obtained a p value of 0.000 (p value <0.05) interpreted as Ho is rejected so that there is a difference in anatomical information on MRI examination of the shoulder joint in cases of rotator cuff tear with coronal proton density fat sat and coronal STIR sequences. Based on the results of the mean rank value of the Friedman test as a whole, it shows that the MRI examination of the shoulder joint in the case of rotator cuff tear coronal pieces of the proton density Fat Sat sequence has a mean rank of 1.65 and the coronal STIR sequence has a mean rank value of 1.35, which means that the coronal proton density fat sat examination sequence is better in displaying the anatomical image of the MRI shoulder joint compared to the coronal STIR sequence in the case of rotator cuff tear.

The goal of this study was to find out what the CT number meant on a thorax CT scan in Pelura Effusion cases at Bhayangkara Hospital Makassar. This study used a quantitative descriptive study with an observational approach. Based on the results of the research conducted, researchers can conclude that there is an influence of the CT number value on the thorax CT scan examination in pleural effusion cases. In the research that was conducted, the researchers obtained a sample of 2 patients with pleural effusion cases at the Radiology Installation at Bhayangkara Hospital, Makassar. A chest CT scan of a case of non-contrast pleural effusion revealed dense free fluid in the pleural vacuum in the first patient. With the coronal section, the maximum HU value is 22.56 HU and the minimum value is 2.47 HU, while the maximum HU value on the axial section is -7.06 HU and a minimum value of -31.31 HU. In the second patient, the maximum value of the coronal section was 22.09 HU and the minimum value was 9.88 HU, while the axial section had a maximum value of 24.09 HU and a minimum value of 12.25 HU.

Background: The component that can affect image quality is noise. Noise in CT Scan images comes from random variations in photon detection. Scan time is the time it takes for x-rays to exit for data collection of each slice. Pitch is one of the important component parameters in the CT Scan protocol and fundamentally affects the quality of the resulting image, as well as the time required for scanning. The use of pitch in the Radiology Installation of Ibnu Sina Islamic Hospital Pekanbaru in the head CT Scan examination is 0.55. The pitch value variations used by the author in this study are pitch 0.55, 0.75, 1, 1.25 and 1.5.Methods: This type of research is quantitative research using an experimental approach. The study was conducted to determine the effect of pitch value variation on image quality (noise) and scan time using a water phantom on head CT Scan examination protocol using pitch 0.55, 0.75, 1, 1.25 and 1.5. A sample of 10 CT Scan images was taken, and the image quality (noise) was measured by identifying a specific region in the image (Region of Interest or ROI), while the scan time value was observed from the consul monitor. Data analysis was performed using one-way ANOVA statistical test with a significance level of 5%.Results: The results show that there is a significant difference in image quality (noise) on pitch value variation, with a significance level of 0.004, and there is also a significant difference in scan time on pitch value variations with a significance level of less than 0.001. Conclusions: Based on the conclusion, pitch 1 is the value that produces optimal noise level and scan time in head CT Scan protocol using water phantom.
