Clinical value of 3.0T MRI for hilarcholangiocarcinoma diagnosis / 医疗卫生装备

ABSTRACT

Objective To investigate the clinical value of 3.0T MRI for hilarcholangioc-arcinoma diagnosis.Methods T Totally48 hilarcholangiocarcinoma patients from October 2011 to June 2015 underwent diagnoses by 3.0T MRI and 64-slice spiral CT,and then the diagnosing results were compared with those by surgery and pathological examination to determine the value of 3.0T MRI for hilarcholangiocarcinoma diagnosis.Results 3.0T MRI had the positioning accuracy (100％) and qualitative accuracy (95.83％) significantly higher than the positioning accuracy (79.17％) and qualitative accuracy (81.25％) (P＜0.05).In case of hepatic duct dilatation,CT found 35 cases of hilar masses,14 cases of lymphoma,5 cases of hepatic duct wall invasion and 9 cases of portal vein invasion,while 3.0T MRI displayed 44 cases of hilar masses,26 cases of lymphoma,13 cases of hepatic duct wall invasion and 30 cases of portal vein invasion.Conclusion 3.0T MRI has high positioning and qualitative accuracies when used to diagnosing hilarcholangiocarcinoma,behaves well in displaying hepatic duct dilatation,high resolution of soft tissues,and thus is worthy promoting clinically.
