Abstract

BACKGROUND: Magnetic Resonance Cholangiopancreatography (MRCP) is an examination that provides detailed anatomical andpathological information from the biliary tree and pancreatic duct Which combines cross sectional and projectional technique. 3D SequencesHR sMRCP, and 2D SSh are techniques for obtaining MRCP imagery. The purpose of this research is to know the difference of imageanatomical information between 3D HR sMRCP sequence and 2D SSh sequence in case of joundice suspect CBD stone.METHODS: This research type is experiment. This study was conducted by MRI Philips Ingenia 1.5 Tesla plane in Dr. RSAL. RamelanSurabaya. The data were 16 MRCP images of 8 patients with a case of joundice suspect CBD stone, sequences used 3D HR sMRCP, and 2DSSh on MRCP examination.Imagery assessment is done quantitatively in the form of an observer's assessment of anatomical informationincluding Gall bladder, Cystic Duct, Common Bile Duct, Intra Hepatic Bile Duct, and clarity of stone images. Quantitative data analysis withCohens Kappa test, cross tabulation and Wilcoxon test.RESULT: The results stated that there was no significant difference in overall image information between 3D HR sMRCP sequences and 2DSSh sequences with p value 0.083 (p> 0.05) and confident level 95%. Gall bladder value p = 0.083; Common bile duct p = 0.059; Cystic Ductp = 0.063.However there was a significant difference in Intra hepatic Bile Duct with p = 0.034; And stone clarity image p = 0.038. The meanoverall rank value of anatomical image information in 3D Hr sMRCP sequence is higher than the mean rank value of 2D SSh sequence.Except for the image of clarity of stone, the mean value of 2D SSh 3.00 is superior compared to the mean rank value of 3D Hr sMRCPsequence of 0.00.CONCLUSSIONS: In general, 3D Hr sMRCP sequences have better capabilities than 2D SSh sequences in displaying anatomical Biliary treeimage information. But in the image clarity 2D SSh stone is better than 3D Hr sMRCP.
