原发性肝癌的螺旋双期增强扫描特征和诊断价值

目的 探讨原发性肝癌的螺旋CT双期增强特征及其诊断价值.方法 回顾性分析36例经临床及手术病理证实的原发性肝癌双期增强表现.结果 36例共发现42个病灶.平扫呈低密度或等密度;肝动脉期90.5%强化,9.5%无明显强化;门脉期76.2%呈低密度或稍低密度,病灶密度呈"速升速降"的变化特点.结论 螺旋CT双期扫描可充分反映原发性肝癌的特征,对肝癌的检出和定性准确率的提高有重要价值.

The diagnoses value of dual phase spiral CT in primary hepatocellular carcinoma and scanning characteristic

Objective Evaluation the characteristic and diagnoses value with dual phase spiral CT in primary hepatocellular Carcinoma. Methods We review analyse 36 examples hepatocellular Carcinoma that had approved by pathology verify or surgical operation dual-phase spiral CT scanning characteristic. Results 42 focus were found among 36 examples altogether. They revealed the low density or the low density slightly in plain scanning; 90.5% of Primary liver cancer was enhanced in arterial phase.9.5% were not enhanced obviously; 76.2% were reveal the low density or the low density slightly in portal venous phase, focus presents the change characteristic of ising and lower rapidlyy density. Conclusion Dual phase spiral CT is an important value in the detection and characterization of primary hepatocellular Carcinoma, it can improve rate of accuracy examine and determine the nature.
