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.

One of the clinical features that can be found in Thorax is emphysema. Emphysema is one of the pathological processes of the lung parenchyma in COPD (Chronic Obstructive Pulmonary Disease). The patient must inhale and exhale with a larger volume of air in order to meet the metabolic needs of oxygen distribution (O2), removal of carbon dioxide (CO2) and maintaining acid-base balance. MSCT has an important role in diagnosing emphysema. One of the biggest drivers for technical improvement in MSCT is image quality. MSCT Scan image quality is influenced by several factors, namely spatial resolution, resolution contrast, noise, and artifacts. One of the parameters that affect image quality is the selection of slice thickness. Slice thickness is the thickness of the slice or slice of the object being examined. Thorax MSCT scan is routinely performed using a slice thickness of 1.25 – 5 mm. Thorax examination in cases of emphysema used a slice thickness of 0.5 mm – 1.5 m.This type of research is quantitative with an experimental approach. This study was conducted by analyzing the effect of slice thickness variations on image quality and anatomical information of MSCT Scan Thorax in cases of Emphysema. Based on the results of the Friedman test overall, it shows that there is an influence of image quality and anatomical information on the MSCT Scan Thorax examination in cases of emphysema using slice thickness variations of 1.5mm, 3mm and 4.5mm on spatial resolution, contrast resolution, and noise. Based on the results of this study, the researcher can recommend the MSCT Scan Thorax examination in cases of emphysema using a slice thickness of 1.5mm with the aim that the results of image quality and anatomical information on the MSCT Scan Thorax examination in cases of emphysema look clear and good.

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.

Hemorrhagic stroke is the rupture of blood vessels in the brain, resulting in reduced blood flow (ischemia) and hypoxia. One of the disorders that can be diagnosed through sophisticated modalities is a CT scan, because it can be done quickly and accurately when evaluating bleeding in the brain. The slice thickness used in CT scans of the head in hemorrhagic stroke cases is 5 mm-10 mm, carried out using a one range protocol, namely from the basic cranii to the vertex. Slice thickness is the thickness of the slice that can be selected according to clinical needs. The factors used to evaluate image quality are spatial resolution, resolution contrast and noise. This research is quantitative by taking an experimental approach to analyze the effect of using slice thickness variations of 3mm, 4mm and 5mm on image quality (spatial resolution, resolution contrast and noise) on CT scans of the head in cases of hemorrhagic stroke of 10 samples. Based on the results of the research carried out, the researchers can conclude according to the overall results of the Friedman test that there is an influence on the image quality of CT scans of the head in hemorrhagic stroke cases using slice thickness variations of 3mm, 4mm and 5mm on spatial resolution, contrast resolution and noise. So based on the results of the Friedman test per image quality, there is a difference in the image quality of CT scans of the head and cases of hemorrhagic stroke which use slice thickness variations of 3mm, 4mm and 5mm. Based on the results of the mean rank of the Friedman test, slice thickness 5mm has a mean rank of 2.88 with the highest value. Based on the results of this study, researchers can recommend that CT scans of the head in cases of hemorrhagic stroke use a slice thickness of 5 mm with the aim that the image quality results in CT scans of the head in cases of hemorrhagic stroke look clear and good.
