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56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:56例共发现82个病灶。平扫呈低密度或等密度;肝动脉期91%强化,9%无明显强化;门脉期76%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。
Objective: To investigate the characteristics of spiral CT double-phase enhancement of primary liver cancer and its diagnostic value. Methods: Retrospective analysis of 56 cases of primary liver cancer confirmed by clinical and surgical pathology enhanced performance. Results: A total of 82 lesions were found in 56 cases. Swelling showed a low density or equal density; Hepatic arterial 91% enhanced, 9% no significant enhancement; portal venous 76% showed low density or slightly lower density, lesion density was “rapid rise and fall ” changes. Conclusion: Spiral CT double-phase scanning can fully reflect the characteristics of primary liver cancer, liver cancer detection and qualitative accuracy rate of great value.
