肝血管瘤与肝癌非延迟CT扫描的鉴别诊断

分析肝血管瘤与肝癌在一过性非延迟增强扫描的ＣＴ增强表现，并寻找它们的特点，对经穿刺活检及手术病理检查证实的３１例肝肿瘤病人的ＣＴ资料（肝血管瘤１６例，肝癌１５例）作回顾性分析，所有病人均行平扫后立即做传统团注增强扫描，描述：病灶增强的类型，病灶强化的程度，强化组织的分布，造影剂用量为１．５ｍＬ／ｋｇ体重，结果，８１％的肝血管瘤及８％的肝癌病灶可见以球关或结节状强化（Ｐ〈０．０５）。８１％的肝血管瘤

Distinction between Hepatic Cavernous Hemangioma and Hepatocellular Carcinoma on Enhanced CT without Delayed Images

To analyse contrast-enhanced CT appearance without delayed images for differentiating hepatic cavernous hemangioma (HCH) and hepatocellular carcinoma (HCC),CT manifestations of 31 patients with HCH (16 patients) and HCC (15 patients) were retrospectively evaluated. CT examinations were pre formed with no-delayed scan following bolus injection of 1. 5mL/kg of contrast material. All lesions were evaluated based on the following criteria: type of enhancement, degree of enhancement,distribution of enhancement.81% of HCH had globular enhancement compared to 7% of HCC (P<0. 05). 81% of HCH had enhancement isodense with the aorta and all the HCC lesions had not this signs (P<0.01). 81% of HCH and 43% of HCC had globular and peripheral enhancement (P<0.05).13% of HCH and 53% of HCC had diffuse and heterogedeous enhancement (P<0.05). The lesion with globular and peripheral enhancement that is hypo-or isodense with the aorta is highly characteristic of HCH on no-delayed images,but the lesion with linear, diffuse and heterogeneous is most appearances of HCC.
