The value of MRCP combined with CT or MRI dynamic contrast-enhanced scan in biliary obstruction / 实用放射学杂志

ABSTRACT

Objective To investigate the value of MRCP in conjunction with CT or MRI contrast-enhanced scan in locating and qualitative diagnosis of biliary obstruction.Methods 954 patients with biliary obstruction confirmed by surgical pathology and clini-cal follow up underwent MRCP scans in our hospital.Contrast-enhanced CT scans in 87 patients,contrast-enhanced MRI scans in 52 and both CT and MRI enhancement in 37 were performed.Results The accuracy of location of biliary obstruction with MRCP was 100%,the accuracy of quality of biliary obstruction with MRCP combined with CT or MRI dynamic contrast-enhanced scan was 96%.Conclusion MRCP combined with CT or MRI dynamic contrast-enhanced scans has an important clinical value for the locali-zation and qualitative diagnosis of biliary obstruction.
