目的:探讨彩色多普勒超声(CDFI)鉴别诊断良、恶性骨肿瘤。方法:对30例骨肿瘤病人进行了CDFI检查,分别测量肿瘤周边部及内部血流最大血流速度(Vmax),最小血流速度(Vmin)、平均血流速度(Vm)、阻力指数(RI)、搏动指数(PI),并与手术、病理对照。结果:CDFI对良、恶性骨肿瘤诊断准确率90%,特异度91.2%。结论:CDFI是一种简便的术前判断良、恶性骨肿瘤的临床诊断方法。
Objective: To investigate the differential diagnosis of benign and malignant bone tumors by color Doppler ultrasound (CDFI). METHODS: CDFI was performed on 30 patients with bone tumors. The maximum blood flow velocity (Vmax), minimum blood flow velocity (Vmin), mean blood flow velocity (Vm), and resistance index (RI) in peripheral and internal blood flow were measured. ), Pulsatility index (PI), and compared with surgery and pathology. Results: The diagnostic accuracy of CDFI for benign and malignant bone tumors was 90% and the specificity was 91.2%. Conclusion: CDFI is a simple method for clinical diagnosis of benign and malignant bone tumors before operation.
