目的：应用CT动脉门脉造影(CTAP)和CT动脉造影比较早期肝细胞癌(HCC)和小肝癌的血流动力学特征。材料和方法：对37例(男26例，女11例，年龄52~74岁，平均59.2岁)的44个早期肝细胞癌(平均直径1.5 cm)进行研究。其中早期肝癌35例，CT动脉造影20例，两者均为11例。对57例(男44例，女13例，年龄48~71岁，平均61岁)90例小肝癌(平均直径2.0 cm)进行了CTAP和/或CT动脉造影检查。结果：CTAP显示23例早期肝癌为低密度肿块，12例为等密度肿块。CT动脉造影显示早期肝细胞癌呈低密度肿块，6个呈等密度，3个呈高密度。CTAP显示88例小肝癌中85例为低密度肿块，3例为等密度肿块。CT动脉造影显示14例小肝癌中13例为高密度肿块。结论：CTAP作为小肝癌诊断的参考标准，对早期肝癌的诊断不够敏感。
PURPOSE: To use computed tomography (CT) during arterial portography (CTAP) and CT arteriography to compare the hemodynamic properties of early hepatocellular carcinoma (HCC) with those of small HCC.MATERIALS AND METHODS: Forty-four early HCCs (mean diameter, 1.5 cm) in 37 patients (26 men and 11 women aged 52-74 years; mean age, 59.2 years) were studied. CTAP was performed on 35 early HCCs, CT arteriography on 20, and both studies on 11. CTAP, CT arteriography, or both were performed on 90 small HCCs (mean diameter, 2.0 cm) in 57 patients (44 men and 13 women aged 48-71 years; mean age, 61 years). The findings for small HCC were compared with those for early HCC.RESULTS: CTAP depicted 23 early HCCs as hypoattenuating masses and 12 as isoattenuating. CT arteriography depicted II early HCCs as hypoattenuating masses, six as isoattenuating, and three as hyperattenuating. CTAP depicted 85 of 88 small HCCs as hypoattenuating masses and three as isoattenuating. CT arteriography depicted 13 of 14 small HCCs as hyperattenuating masses.CONCLUSION: CTAP, the standard of reference for the detection of small HCC, is not sensitive enough for the detection of early HCC.
