Backgroud: Urolithiasis is the formation of crystalline mineral deposits in the urinary system. Examination of MSCT Urographic with and without administration of intravenous contrast media is used to detect various abnormalities in the urinary tract area. This study aims to analyze MSCT Urographic examination procedures in patients with clinical Urolithiasis at the Radiology Unit of Premier Bintaro Hospital.Methods: Type of study is qualitative with a case study approach. Collection data was conducted at the Radiology Unit of Premier Bintaro Hospital with specialists and documentation observation methods, interviews with radiographers and radiology. Data processing and analysis are carried out descriptively related to the results of observation, interviews and documentation so that conclusions and suggestions can be drawn.Results: Urographic MSCT examination in patients with clinical Urolithiasis performed with patient preparation by laboratory check to check kidney function (urea and creatinine), examination was performed using the MSCT rutine protocol with the addition of contrast media by scanning the unenhance phase, enhance phase includes arterial phase, phase portal vein and delay phase which is 7 minutes and 15 minutes with prone patients in the kidney vesica urinaria area, and post void. The addition of contrast media is intended to show enhancement and narrowing of the urinary tract.Conclusion: Examination of MSCT Urography in patients with clinical Urolithiasis in the Radiology Unit of Premier Bintaro Hospital is done with patient preparation laboratory check, the protocol is done by scanning the unenhance and enhance phases.

Backgroud: Brain MRI examination generally has a long scanning time because many protocols that must be used, one of them is DWI sequences, which are sequences that can provide pathological information on the brain. One way to reduce scan time is to use parallel imaging sensitivity encoding (SENSE) techniques. SENSE utilizing the spatial information RF coil phased array to reduce the acquisition time by reducing the number of sampling lines K space therefore produce quality and good spatial resolution, but its has the limitations, namely the reduction of SNR. The purpose of this research was to analyze in SNR onĀ  the variations of SENSE value in MRI brain DWI axial slices.Methods: This research is a quantitative study with an experimental approach in 15 patients MRI Brain. Data was taken by calculating the SNR value for the region of interest (ROI) in cortex cerebri, basal ganglia, thalamus, pons and cerebellum, and then ROI in noise background. Data was analyzed through Repeated Measures Anova test by comparing the differences in SNR values obtained in MRI brain DWI axial between the use of various SENSE values, that are 2.0; 3.0 and 4.0.Results: MRI image of DWI axial brain sequence with variation of reduction factor 2.0; 3.0 and 4.0 cause different SNR values. The highest SNR is found in the variation of 2.0 and the lowest value is 4.0 but the scan time is fastest at the 4.0 variation This is because there is a reduction in the phase encoding line in the K-space on each image using SENSE and the higher the reduction factor, the higher the reduction factor. SNR will decrease.Conclusion: The higher the value of SENSE variations will decrease the SNR value but the scan time is faster.
