摘要
目的通过螺旋CT动脉门静脉造影(SCTAP)、螺旋CT动脉造影(SCTA)与肝动脉造影比较,显示小肝癌的血流动力学特性及影像特征。方法22例原发性肝细胞癌(HCC)或HCC术后肝内转移病人(男18人、女4人,年龄34～65岁,平均44.6岁),共79个病灶(0.1～3cm,平均直径1.8cm)。5例SCTAP与17例SCTA,结果分别与肝动脉造影术比较。结果5例SCTAP显示28个小病灶中,26个低密度,2个等密度;17例SCTA发现51个病灶,42个表现为高密度,9个表现为等密度;两组血管造影分别显示17、32个病灶,其中高密度41个,等密度8个。与血管造影相比,SCTAP显示小于2cm的病灶及所有小于3cm的病灶数差异具有显著性(P<0.05)或高度显著性(P<0.01);SCTA对小于3cm的病灶数较血管造影有显著性差异(P<0.05。)结论SCTAP及SCTA可准确反映小肝癌的血流动力学特性,在显示小肝癌方面优于肝动脉造影,可以为临床提供更丰富的影像学资料。
Objective To understand the hemodynamic properties and the imaging features of sma ll hepatocellular carcinoma through comparing the findings of spiral com puted tomography during arterial portography(SCTAP)and spiral CT arteriography(SCTA)with that of hepatic arteriography.Methods 71small HCCs (mean diameter,1.8cm)in 22patients(18men and 4women aged 34～65;mean age,44.6years)were studied.SCTAP were performed i n 5patients,SCTA in 17patients.The findings for small HCC were compared with those of hepat-ic angiography,respectively.Result SCTAP depicted 28small HCCs,26as hypoattenuating masses and 2as isoatt enuating.SCTA depicted51lesions,41as hyperattenuating masses and 2as isoattenuating.while angiography depicted 17,32lesions,respectively.SCTAP had high significant difference(P <0.01)from angiography in demonstrating t he number of lesions less than 3cm.SC TA has significant difference(P<0.05)in demonstrating the number of the le sions.Conclusion Both SCTAP and SCPA can reflect hemod ynamic properties of small HCCs better than angiography.They are re liable methods for detecting small H CCs,and can give more clinical information to stipulate for right thera-peutic scheme.[
