Abstract:
PURPOSE: To prospectively assess the utility of the three-dimensional T1 weighted magnetic resonance cholangiography (MRC) with Gd-EOB-DTPA (Primovist(R)) in patients suspected of having a mild common bile duct obstruction. MATERIALS AND METHODS: A total of 30 patients suspected of having a mild common bile duct obstruction were enrolled in this study. A T2 weighted MRC and a three-dimensional T1 weighted MRC with Gd-EOB-DTPA (Primovist(R)) were performed. Within 48 h of the MRC, we performed direct cholangiographies by way of an endoscopic retrograde cholangiography and a surgical cholangiography. Reviews of the data by two experienced radiologists were in consensus. RESULTS: Within 40-60 min of the injection of contrast fluid, the contrast showed the maximum intensity within a common bile duct in 26 of the 30 patients (87%). However, the contrast was poorly visible for as long as 2 hours after injection in 4 of the 30 patients (13%). The sensitivity, specificity, as well as the positive and negative predictive values of the three-dimensional T1 weighted MR cholangiography were 92%, 40%, 88%, and 50%, respectively. CONCLUSION: The three-dimensional, T1 weighted MRC with Gd-EOB-DTPA (Primovist(R)) may be a useful ancillary diagnostic modality for evaluating a patient with mild common bile duct obstruction.
