目的 :评价螺旋CT经动脉门静脉造影 (SCTAP)对肝癌的检测和治疗的临床应用价值。方法 :比较 2 3例肝局灶性病变采用SCTAP、常规CT、DSA显示病灶个数的差异性 ,分析肝局灶性病变SCTAP影像学征象。结果 :SCTAP较常规CT及DSA对显示小于 30 .0mm病灶数及小于 10 .0mm病灶数差异有高度显著性 (P <0 .0 1)或有显著性 (P <0 .0 5 ) ,而对大于 30 .0mm病灶的显示 ,差异无显著性 (P >0 .0 5 )。病灶周边可有门脉供血而内部无门脉供血是肝癌的特征性表现。SCTAP为肝癌的可切除性判断及介入治疗方案的选择提供了有价值的信息。结论 :SCTAP与常规CT、DSA比较 ,对小肝癌或微小肝癌的检测具有极高的敏感性 ,结合其它影像学手段 ,可明显提高其特异性。对于肝癌治疗方案的选择 ,SCTAP具有较大的临床应用价值。
Objective: To evaluate the clinical value of spiral CT portography of arterial portography (SCTAP) in the detection and treatment of liver cancer. Methods : The differences in the number of lesions were compared between SCPD, conventional CT, and DSA in 23 cases of focal liver lesions. The CT imaging signs of focal liver lesions were analyzed. RESULTS: Compared with conventional CT and DSA, SCTAP showed a significant difference (P < 0.01) or significant (P <0.05) between the number of lesions less than 30.0 mm and the number of lesions less than 10.0 mm. There was no significant difference in the display of lesions larger than 30.0 mm (P > 0.05). Peripheral blood supply can be around the lesion and no internal portal blood supply is a characteristic manifestation of liver cancer. SCTAP provides valuable information for the judgment of resectability of liver cancer and the choice of interventional treatment options. Conclusion: Compared with conventional CT and DSA, SCTAP has extremely high sensitivity to the detection of small hepatocellular carcinoma or micro hepatocellular carcinoma. Combined with other imaging methods, the specificity of SCTAP can be significantly improved. For the selection of treatment options for liver cancer, SCTAP has great clinical application value.
