早期肝细胞癌的CT诊断

目的:探讨早期肝细胞癌(HCC)的CT表现特点。方法:回顾性分析48例59个经病理证实的早期HCC的资料。全部病例术前均行CT平扫和增强后动脉及门静脉期扫描。结果:早期HCC的CT表现分为3种类型:平扫、增强动脉期及门静脉期扫描均表现为低密度,共28个病灶(47.46%);平扫呈等密度,增强动脉期及门静脉期扫描表现低密度,共19个病灶(32.20%);平扫及增强动脉期扫描均呈等密度,门静脉期扫描呈低密度,共12个病灶(20.34%)。结论:对有慢性肝病病史的患者,在CT增强前及增强后动脉期、门静脉期扫描表现为低-低-低、等-等-低密度的病灶,应考虑为早期HCC。

Early Hepatocellular Carcinoma and the CT Diagnosis

Objective Re-identifying the early hepatocellular carcinomas and the CT diagnosis.Methods Analysis the data of 48 Cases 59 early HCG with Pathology Conform. All patients were performed plain CT scan and arterial phase veinnal phase scan after contrast enhancement.Results The CT appearance of early hepatocellular carcinoma were classified three patterns.The nodular lesions were seen in 28 lesions (47.46%).Aiso-low-low density pattern in 19(32.20%)onunenhanced,arterial phase and veinnal phase CT scans.The nodular lesions were isodense on plain and arterial phase CT scans,and were low density on veinnal phase (iso-iso-low).This pattern was seen in 12 lesions (20.34%).Conclusion The diagnosis of early hepatocellular carcinoma should be considered in those of people who were chronic hepatic disease if it shows a small lesion with a low-low-low,iso-low-low or iso-iso-low density on plain CT scans,arterial and veinnal phase after contrast enhanced CT scans.
