Abstract:
Objective The aim of this study was to evaluate magnetic resonance cholangiopancreatography(MRCP)using half-Fourier acquisition single-shot fast spin-echo(HASTE)sequence in the diagnosis of biliary obstructions.Methods Forty-five patients with pancreaticobiliary duct diseases underwent MRCP on 1.5 T scanner,a heavily T 2-weighted HASTE was used during a breath-hold.The source images were three-dimensional reconstructed postprocessed on workstation.The findings of MRCP images were analyzed and compared with US,CT,ERCP or PTC.Results The diagnostic accuracy of MRCP was 94%,the same as ERCP(92%),but it was superior to US and CT(?
