螺旋CT对原发性肝癌的诊断价值

目的探讨螺旋CT对原发性肝癌的诊断价值。方法回顾性分析58例经临床及病理证实的原发性肝癌患者的螺旋CT双期扫描表现。结果58例共发现病灶89个。其中肝左叶35个．肝右叶64个。肿瘤大小0．5-17．9cm，平均4．2cm。平扫发现病灶53个，27个表现为低密度，密度均匀者19个，7个不均匀密度病灶中可见到更低密度的坏死区或脂肪变性。肝动脉期扫描发现病灶82个，高密度均匀性强化75个，不均匀性强化6个，有1个无明显强化仍为低密度。门静脉期扫描发现病灶73个，均转化为稍高密度或等低密度影。结论螺旋CT能充分反映肝癌的血供特点，可为原发性肝癌的诊断提供更多可靠的信息及病变特征。

The Value of Spiral CT on Diagnosis of Primary Liver Cancer

Objective To evaluate the value of spiral CT on diagnosis of primary liver cancer. Method To retrospective analyze 58 cases of pri mary liver cancer patients＇ performance which were confirmed clinically and pathologically by dual-phase helical CT scan. Results 89 lesions were found. Left lobe of liver had 35 lesions, while the right lobe had 64 lesions. The tumor size was 0.5 - 17.9 cm, and its average was 4.2 cm. Planar sweep found 55 lesions; 27 lesions showed low density, 19 lesions showed uniformity density; 7 lesions of non-uniform density could be seen more low density areas of necrosis or fatty degeneration. Hepatic arterial phase scan showed 82 lesions; 75 lesions showed high density ho mogeneous enhancement; 6 lesions showed inhomogeneous enhancement; 1 lesion had a low density and no-significantly enhanced. Portal ve nous phase scan found 73 lesions which were translated into slightly higher density or isodense shadow. Conclusion Spiral CT can fully reflects the characteristics of liver cancer blood supply; It can provide more reliable information and pathological characteristics on the diagnosis of primary liver cancer.
