摘要: The authors investigated the magnetic resonance appearance of hepatocellular carcinoma using a 1.5-Tesla magnet. Twenty-four patients with pathologically proven had imaging (MRI) studies, which were retrospectively reviewed. All imaged at least two following techniques: (1) T1-weighted (T1W), (2) Gd-DTPA enhancement (T1W-E), (3) T2-weighted (T2W), (4) proton density (PD), and (5) gradient-recalled echoes (GRE). T1W images equal to T2W for tumor detection grading system. slightly better than total number lesions detected. other pulsing techniques (PD, T1W-E, GRE) detected fewer lesions. Eight cases (33%) nonhomogeneous increased signal intensity on both images. conclude that are carcinoma. also 33% carcinomas have an pattern This is atypical most hepatic masses hence can be used suggest mass
