快速动态增强CT对恶性肝肿瘤的诊断价值

目的：本文目的是确立快速动态增强ＣＴ对恶性肝肿瘤的诊断价值。材料和方法：有快速动态增强ＣＴ检查的３０例肝恶性肿瘤病人同平扫和延迟扫描进行回顾性比较研究。结果：平扫ＣＴ肿瘤呈低密度２２例，等密度８例。快速动态增强ＣＴ显示肿瘤２９例，１例肿瘤呈等密度强化。延迟扫描显示肿瘤２７例，３例肿瘤呈等密度强化。结论：对门静脉瘤栓、肿瘤包膜和原发肿瘤显示上，增强ＣＴ显示优于平扫，我们认为快速动态增强ＣＴ与平扫ＣＴ和延迟扫描比是发现肝肿瘤最敏感的方法，应该成为标准ＣＴ检查方法。

Malignant Hepatic Tumors:Rapid Dynamic Contrast-Enhanced CT

PURPOSE:was identify the value of rapid dynamic contrast-enhanced CT in patients with malignant hepatic tumors.MATERIAL AND METHODS: Thirty patients were examined with rapid dynamic contrast-enhanced CT, as compared to noncontrast CT and delayed post-contrast CT.RESULTS: On noncontrast CT, the tumors were hypodense relative to normal liver in 22 patients and isodense in eight. Rapid dynamic contrast enhanced CT showed better conspicuity of the tumors in 29 and to become isodense of the tumor in one. Delayed post-contrast CT showed conspicuity of the tumors in 27 and to become isodense of the tumors in three.CONCLUSION: Dynamic contrast-enhanced CT had the advantage over noncontrast CT in showing portal vein thrombus, tumor capsule and primary tumors.Our study suggests that rapid dynamic contrast-enhanced CT has much sensitive method of detecting liver neoplasms than noncontrast CT and delayed post-contrast CT.
