【摘要】 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。更多还原

【Abstract】 Purpose: To evaluate the effectiveness of three-phase spiral computed tomography (CT) for the evaluation of hepatocellular carcinoma (HCC). Material and methods: Images obtained at three-phase spiral CT in 32 patients with 59HCC were reviewed. The number of the detected lesions were calculated on each phase and the pattern of enhacement observed. The CT appearances were independently reviewed in a double blind method by two radiologists. Results: The detectability of HCC in the arterial-phase (AP), portal-phase (PP), and delayed-phase(DP) were respectively 52 (88% ), 45 (76% ), and 44 (75 % ). Twelve lesions were detected only with the AP, one with the PP,and two with the DP. Conclusion: Lesion detectedand conspicuity were best with the AP, However,some lesions were detected only with the DP and PP, so that maximum lesion visualization is achieved by using all three phases.更多还原
