The comparison of MRCP and Gd-EOB-DTPA-enhance d MR in the diagnostic value for biliary obstruction disease / 中国医师杂志

ABSTRACT

Objective To evaluate the diagnostic value of MRCP and Gd -EOB-DTPA-enhanced MR for biliary obstruction dis -ease, and provide basis to choose the suitable method for this patient .Methods A respectively analysis was carried out from 2011 to 2013in 138 biliary obstruction cases.All the cases had undergone both MRCP and Gd -EOB-DTPA-enhanced MR examinations and fi -nally proven by pathology .A comparison was made in these two methods .Results All the 138 cases by MRCP and Gd-EOB-DTPA-enhanced MR were successful.The same diagnosis based on MRCP and Gd -EOB-DTPA-enhanced MR was 86 cases (62.3%).The different diagnosis was 52 cases.In the 52 different cases, MRCP was tumor, Gd-EOB-DTPA-enhanced MR was stone and MRCP was stone, Gd-EOB-DTPA-enhanced MR was normal.Conclusions MRCP is a noninvasive diagnostic modality capable of producing high quality imagines of bile duct and pancreatic tract .It has a high sensitivity and specificity in the evaluation of the bile duct and pancreatic tract.The efficacy of Gd-EOB-DTPA-enhanced MR is sufficient to justify its use in the diagnosis of bile duct and pancreatic tract diseases.Gd-EOB-DTPA-enhanced MR has a similar diagnosis effectiveness in bile duct obstruction .
