为了评价三期螺旋CT检查肝细胞癌的价值。材料与方法：对32例患者59个肝细胞癌进行三期螺旋CT扫描。统计各期病灶的检出数．观察病灶增强方式。由两位放射科医生以双盲法观察诊断。结果：肝细胞癌在肝动脉期、门静脉期和延迟期的检出率分别为52个（88％），45个（76）和44（75％）。12个病灶仅显示在动脉期，1个病灶仅显示在门静脉期，2个病灶仅显示在延迟期。结论：动脉期显示的病灶数最多，然而，有些病灶仅显示在门静脉期和延迟或．因此．为了能最大限度显示病灶，三期螺旋CT的采用是必要的。
To evaluate the value of three-phase spiral CT for hepatocellular carcinoma. Materials and Methods: Three-phase helical CT scans were performed on 32 hepatomas of 32 patients. Statistics the number of lesions detected in each phase. Observe lesion enhancement. The diagnosis was observed by two radiologists in a double-blind manner. RESULTS: The detection rates of hepatocellular carcinoma in the hepatic arterial phase, portal vein phase, and delayed phase were 52 (88%), 45 (76), and 44 (75%), respectively. Twelve lesions were only displayed in the arterial phase, one lesion was only displayed in the portal vein phase, and two lesions were only displayed in the delayed phase. Conclusion: The number of lesions displayed in the arterial phase is the most, however, some lesions are only displayed in the portal venous phase and delayed or. therefore. In order to maximize the display of lesions, the use of three-phase spiral CT is necessary.
