摘　　要：目的探讨CTHA、CTAP和碘油CT(Lp-CT)在判别原发性肝癌术后小复发灶,特别是手术口周复发与瘢痕灶的应用价值。方法分析8例原发性肝癌术后患者19个≤3cm复发灶及手术口瘢痕的螺旋CT、DSA、CTHA、CTAP和Lp-CT表现。结果 Lp-CT19个碘油沉积灶,其中16个肝内病灶。螺旋CT、DSA、CTHA和CTAP结合检出个数分别是12、9、15,检出率分别是75%、56.3%、93.8%。手术瘢痕周围3个小复发灶,螺旋CT、DSA、CTHA和CTAP均未明确显示。结论 CTHA和CTAP结合是发现肝内复发小肝癌灶最敏感的方法,Lp-CT在发现微小肝癌和肝癌术后瘢痕周围小复发灶优于CTHA、CTAP。CTHA、CTAP和Lp-CT结合是区别肝癌术后瘢痕和复发灶最敏感的方法。Objective To discover CTHA,CTAP and Lp-CT＇s value in diagnosing postoperative recurrence of small hepatocellular carcinoma lesions,particularly around surgical operation and scar.Methods Images of nineteen recurrent lesions and surgical scar on spiral CT,DSA,CTHA,CTAP and Lp-CT were analyzed,which was from eight primary liver cancer patients.Results On Lp-CT film there were nineteen lipiodol deposit foci,in which there were sixteen in liver,but on spiral CT,DSA,CTHA and CTAP film we found 12,9,15 lesions respectively.The detection rate of spiral CT,DSA,CTHA and CTAP were 75%,56.3%,93.8%.We found three little recurrent lesions around the surgical scar by LpCT film,but no recurrent lesion by spiral CT,DSA,CTHA and CTAP film.Conclusion The combination of CTHA and CTAP is the most sensitive method in diagnosing postoperative recurrence of small hepatocellular carcinoma lesions.Lp-CT is better than CTHA and CTAP in diagnosing mini hepatocellular carcinoma and recurrent lesions around the surgical scar.The combination of CTHA,CTAP and Lp-CT is the most sensitive method in differentiating scar and recurrent lesions after surgical operation.[
