螺旋CT双期增强特征对原发性肝癌的诊断价值

目的探讨螺旋CT双期增强特征对原发性肝癌的诊断价值。方法回顾性分析56例经临床、手术病理、DSA、B超等证实的原发性肝癌患者螺旋CT双期增强扫描表现,总结肿瘤在动脉期及门脉期的各种强化特征。结果 56例共发现88个病灶。平扫发现病灶71个(80.68%),可呈低、等或混杂密度,合并脂肪肝时可呈高密度。肝动脉期75个病灶(85.22%)不同程度强化,门脉期83个病灶(94.32%)呈低密度或不均匀低密度,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 spiral CT double period to strengthen the characteristics of primary liver cancer diagnosis value. Methods Retrospective analysis the clinic, 56 cases of surgical pathology, DSA, type-b ultrasonic confirmed the primary liver cancer patients spiral CT scan showed double period, summarizes the tumor in the period of arterial other all sorts of aggrandizement characteristics. Results 56 cases were found 88 lesions. Flat lesions and found 80.68% （71）, but is low, or mixed densities, fatty liver in high-density can. Hepatic arterial 75 lesions （85.22%） different degree of portal period, 83 lesion （94.32%） low density or uneven low density, the density of lesions of ＂Speed dropped liters＂ speed dropped. Conclusion Spiral CT scan can fully reflect the double period of primary liver cancer of the liver, detection, and to improve the accuracy and qualitative have important value.
