摘要
１９９０年１０月至１９９２年２月，我们对１４例病人作了ＣＴＡ检查，其中５例还行ＣＴＡＰ检查。经手术病理证实，１２例为ＳＨＣＣ，２例为肝内炎性假瘤。ＣＴＡ检查时ＳＨＣＣ表现为明显高密度，单层ＣＴＡ还可显示ＳＨＣＣ造影剂快进快出的典型表现。而炎性假瘤为无增强的低密度，ＣＴＡＰ检查时ＳＨＣＣ表现为边缘清楚的低密度灶。在ＣＴＡ图像上，病灶的ＣＴ值直方图分析有助于肝内小病灶的定性。另外我们在ＣＴＡ检查时还对其他的肝脏表现作了分析。我们的经验是：ＣＴＡ和ＣＴＡＰ是发现ＳＨＣＣ最有效的方法，特别是≤１ｃｍ的小病灶。并且ＣＴＡ对肝内小病灶的鉴别有根高价值。对ＡＦＰ阳性而其他方法未发现肝内占位时，应行ＣＴＡ和／或ＣＴＡＰ检查。
Computed tomographic arteriography(CTA)were performed in 14 cases and completed with computed tomographic arterial portography(CTAP) in five of these cases. Twelve cases with small hepatocellular carcinoma(SHCC) and two cases of inflammatory pseudotumor were confirmed by operation and pathology. The density of SHCC on CTA imaging was higher than that of surrounding liver tissue,Characterized by rapid going up and coming down on single level dynamic CTA. But inflammatory pseudotumor was low density without enhancement. On CTAP imaging SHCC was hypodense and welldefined. The other CT appearances on CTA imaging were analytal by authors. It was our opinion that CTA and CTAP were the most useful method in detection of SHCC, especially the lesion equal to and smaller than lcm. And CTA was very valuable in differentil diagnOsis of small lesions in the liver. CAT and/or CTAP must be taken when AFP was high but no lesion was found in the liver by other imaging methodes.
