Computed tomographic arteriography (CTA) was performed in 30 patients with hepatocellular carcinoma (HCC). Detection of HCC by CTA was compared with that of conventional celiac or hepatic arteriography. CT scanning was performed immediately, 30 seconds and 1 min after an injection of 5 to 10 ml of contrast medium into the common or proper hepatic artery. Repeated infusions allowed whole liver sections to be visualized. HCC was localized in 28 of the 30 patients by conventional arteriography, with CTA detecting the masses in 27 of the 28 patients. CTA imaging presented the tumor mass in 1 of the 2 patients missed by arteriography. Conventional arteriography delineated the boundaries of HCC in 15 (50%) of the 30 patients. CTA clearly delineated the masses in 26 (87%) of the 30 patients including 11 patients in which the tumor borders were obscure by conventional arteriography. HCC lesions smaller than 1 cm in diameter were detected only by CTA in 6 (20%) of the patients. It was concluded that CTA is both useful and necessary in the demarcation of small HCC masses.
对30例肝细胞癌（HCC）患者进行了计算机断层血管造影（CTA）检查。将CTA对HCC的检测结果与传统的腹腔动脉或肝动脉造影结果进行比较。在向肝总动脉或肝固有动脉注射5至10毫升造影剂后，立即、30秒及1分钟进行CT扫描。重复注射使整个肝脏断面得以显影。通过传统动脉造影，30例患者中有28例的HCC得以定位，CTA在这28例患者中的27例检测到了肿块。CTA成像显示出动脉造影遗漏的2例患者中的1例的肿瘤肿块。传统动脉造影在30例患者中的15例（50%）勾勒出了HCC的边界。CTA在30例患者中的26例（87%）清晰勾勒出了肿块，其中包括11例传统动脉造影显示肿瘤边界模糊的患者。6例（20%）患者中直径小于1厘米的HCC病变仅通过CTA检测到。结论是CTA在小HCC肿块的界定中既有用又必要。
