Seventeen patients with 52 surgically proven hepatic metastases were studied preoperatively with dynamic CT and 0.5 T magnetic resonance (MR). Dynamic CT detected 38 metastases (73%), and the combination of short echo time (T1-weighted) and T2-weighted pulse sequences detected 46 lesions (88%). Magnetic resonance was also superior at assessing potential resectability. This study suggests that MR excels in detecting and anatomically localizing individual hepatic metastases.
对17例经手术证实有52处肝转移灶的患者术前行动态CT及0.5T磁共振（MR）检查。动态CT检测到38处转移灶（73%），短回波时间（T1加权）和T2加权脉冲序列联合检测到46处病灶（88%）。磁共振在评估潜在可切除性方面也更具优势。本研究表明，磁共振在检测和解剖定位单个肝转移灶方面表现出色。
