摘　　要：目的分析肝癌手术后复发MSCT和DSA的影像学表现,评价两者诊断肝癌手术后复发的价值。资料与方法随机搜集72例肝癌手术后复发患者肝脏MSCT和DSA检查资料,两种检查间隔时间为2～14d。结果复发灶为多发小结节(Ⅰ型)51例(70.83%),单发结节(Ⅱ型)9例(12.36%),大小不等结节(Ⅲ型)12例(16.81%)。10例患者(13.89%)两种检查结果不一致,其中7例DSA结果阳性中,5例DSA小结节病灶显示的个数多于MSCT所显示的个数,2例MSCT检查阴性;3例MSCT结果阳性中,2例MSCT小结节病灶显示的个数多于DSA所显示的个数,1例DSA检查阴性。结论MSCT和DSA检查对于肝癌手术后复发病灶的显示存在一定的差异,各具优缺点,两者相结合有利于提高复发病灶显示率。Objective To evaluate the value of MSCT and DSA in diagnosing the postoperative recurrence of hepatocarcinoma by analysing the results of these two image examinations. Materials and Methods MSCT and DSA data of 72 postoperative recurred patients with hepatocarcinoma were collected, the interval of two examinations was 2 to 14 days.Results In 51 cases (70.83%), the recurred lesions were multiple lesser tubercles (type Ⅰ); 9 cases (12.36%) were solitary tubercles (type Ⅱ); the other 12 cases (16.81%) were unequal tubercles (type Ⅲ). The results of two examinations were discrepancy in 10 patients in the research. 7 cases had positive results in DSA, 5 of which had more numbers of lesser tubercle in DSA than that in MSCT, the other 2 cases with negative results in MSCT. And 3 patients had positive results in MSCT, 2 of which had more numbers of lesser tubercle in MSCT than that in DSA, the other 1 case with negative results in DSA.Conclusion MSCT and DSA have certain difference and their own characteristics in displaying the postoperative recurred lesions of hepatocarcinoma, the combined application of MSCT and DSA will be beneficial to improve the display rate of recurred lesions.
