Background : MRCP is a biliary tract and pancreatic duct imaging technique, one technique that uses a breath hold. The technique speeds up acquisition time by using the Parallel Imaging ARC method so that it reduces the encoding phase on K-Space to reduce breath hold. Therefore it can increase image sharpness and reduce blurring image. The purpose of this study was to determine the differences in anatomical image information between using ARC and without using ARC on MRCP examination of coronal T2 FRFSE sequence pieces and to find better anatomical image information between using ARC and without using ARC on MRCP examination of FRFSE T2 sequences.Method : The type of research conducted by the author is quantitative research with an experimental approach. This research was carried out with 1.5 T MRI at Santo Borromeus Hospital, Bandung. Data in the form of 16 MRCP anatomical images of coronal chunks of T2 FRFSE sequences from 8 patients using ARC and without using ARC. Scores on the image are carried out in the gallbladder, cystic duct, common hepatic duct, intra-hepatic duct, common bile duct and pancreatic duct using questionnaires to 3 radiology specialists (respondents). The results of the respondents were analyzed using Wilcoxon statistical test to find out the differences in MRCP anatomical information on FR2E T2 sequences between using ARC and without using ARC and to find better anatomical image information from the two sequences seen from the mean rank value.Result : The results showed that there were significant differences in MRCP anatomical image information of coronal T2 FRFSE sequences between the use of ARC and without using ARC with a significance value of 0.05. Based on mean rank results, MRCP information on T2 FRFSE sequence coronal pieces using ARC has a mean rank value of 4.50 while MRCP T2 FRFSE coronal sequence sequences using without ARC have a mean rank value of 0.00, meaning FRFSE T2 sequences using ARC have better image information than FRFSE T2 without using ARC.Conclusion : Suggestion, the parallel imaging technique of the ARC method was applied on the MRCP examination of T2 FRFSE sequences and the data from this study could be used as baseline data to add ARC as the operational standard of the MRCP examination procedure.

Background: Stroke is a brain disease where an acute nerve function is occurred due to the cerebral vascular disorders. To establish a diagnosis the stroke, it can be identified by employing the Diffusion Weighted Imaging (DWI) sequence in the MRI examination. Artifacts still exist on the MRI image which in turn reduce the resolution when using the DWI sequence. Adding the PROPELLER data acquisition method in the DWI sequence possibly improves the quality of brain images. The purpose of this study is to know the difference on the quality of anatomical image information between the DWI sequences with PROPELLER and without PROPELLER methods, and to determine adequate anatomical image appearance that created in amongst of the two methods, specifically for the stroke disease.Methods: this research is quantitative research with experimental approach. This study was conducted using MRI 1.5 T at Bethesda Hospital Yogyakarta. Data were 16 images from 8 patients using DWI sequences using PROPELLER without PROPELLER on MRI Brain examination with stroke. The results of the image were evaluated on 7 criteria: cortex cerebri, basal ganglia, thalamus, pons, cerebellum, stroke (infarction) and artifacts using questionnaires given to 3 respondents. Data analysis was done by Wilcoxon test to know the difference of anatomical image information on DWI sequence using PROPELLER without PROPELLER and to know better anatomical image information from both sequences seen from mean rank value.Results: The results shown, there is a significant difference on the quality of anatomical image information and the artifacts between the use of DWI sequence with and without PROPELLER methods ( 0.05). Based on the mean rank results, the DWI PROPELLER sequence has a higher mean rank value 4.50 compared to the DWI sequence without PROPELLER 0.00.Conclusions: The DWI PROPELLER sequence has better image results compared to the DWI sequence without PROPELLER.

Background: Tube voltage (kVp) is one of the exposure factors on a head CT scan that can be varied to achieve a minimal radiation dose. Radiology installation of Bhakti Wira Tamtama hospital has a new CT scan modality that never variation its tube voltage. The variation of tube voltage is 80 kVp, 100 kVp, and 120 kVp. The aim of this research is to know and to analyse the most optimize tube voltage which can produce the best anatomy clarity and has the lowest radiation dose on a head CT scan examination of the base skull area that dominates CT scan examination.Methods: This research is descriptive analytic research conducted with an experimental approach. The study was conducted by varying the tube voltage to be used for head CT scan examination. There are 3 variations of tube voltage 80 kVp, 100 kVp, and 120 kVp where one variation contains 16 images for analyzing the clear anatomy of the base skull area. Then assessed by radiologists as the respondent. Data was analyzed by scoring where score 1 is not clear, score 2 is clear and score 3 is very clear. Radiation dose was obtained from CTDI and DLP records.Results: The results showed that there is no difference in anatomy clarity between variation of three tube voltage with p value 0,135. The anatomical clarity assessed includes anterior skull base, central skull base (fossa cranial middle, sphenoid, temporal bone, petrosous ridge), anterior clinoid processes, posterior margin of the lesser sphenoid wings, anterior and superior rim of the greater sphenoid wings, mastoid, and posterior skull base. All of them is very clear at 100 kVp and 120 kVp with value 100%. But at 80 kVp assessed clear at anterior and posterior skull base. So the value of anatomy clarity at 80 kVp is very clear only 71%. The effect of the difference in tube voltage on the radiation dose on a head CT scan of the base skull area showed a difference in the decrease in radiation dose from 120 kVp to 100 kVp for CTDI 39.9% and DLP 40.19%. There was a decrease in radiation dose from 100 kVp to 80 kVp for CTDI 52% and DLP 49.88%.Conclusion: The tube voltage setting on head CT scan examination of the base skull area can be applied with 100 kVp because this is evidenced by the same total score at 100 kVp and 120 kVp, which is 100% is very clear, while at 80 kVp tube voltage only 71% is very clear. And the radiation dose at 100 kVp is lower than 120 kVp.
