ABSTRACT
[Objective]To investigate the value of multi-phase dynamic enhanced MR scanning with 3D-VIBE sequence in HCC by comparing with enhanced multiple slice computer tomography(MSCT)scanning.[Method]23 patients who were pathologi?cally proven of HCC,and underwent both abdominal enhanced 3.0T MR multi-phase dynamic scanning with 3D-VIBE sequence and enhanced MSCT scanning were enrolled. The enhancement features of HCC on enhanced MR multi-phase dynamic scanning and en?hanced CT scanning were compared.[Results]There were 23 lesions confirmed by pathology. All the 23 lesions were detected by en?hanced MR multi-phase dynamic scanning with 3D-VIBE sequence,and 21 lesions were detected by enhanced MSCT scanning. The enhanced features of"fast enhanced and fast washout"in HCC can be observed more frequently on enhanced MR multi-phase dynam?ic scanning with 3D-VIBE sequence than enhanced MSCT scanning (78.3% vs 54.5%). Obvious enhancement feature can be ob?served more frequently on the enhanced MR multi-phase dynamic scanning when the tumor diameter ≤ 3 cm(P=0.037).[Conclu?sion]The enhanced MR multi-phase dynamic scanning with 3D-VIBE sequence can greatly improve the sensitivity and accuracy of HCC diagnosis,especially for the small HCC(tumor diameter≤3 cm).
