二维超声及彩色多普勒血流显像在原发性骨肿瘤诊断中的价值

目的：探讨二维超声检查及彩色多普勒血流显像（CDFI）技术在骨肿瘤诊断中的应用价值。方法：采用Acuson 128XP／10型及G-50型彩色多普勒显像仪。对93例原发性骨肿瘤患者进行二维及彩色多普勒超声检测观察骨质、骨膜及周围软组织情况，测量血流动力学指标。结果：骨质破坏、骨膜反应、周围软组织肿物在二维图像中显示清晰。CDFI可清晰显示肿瘤内部血流情况。恶性肿瘤收缩期最大血流速度（Vmax），舒张期最小血流速度（Vmin）高于良性肿瘤（P〈0．01），阻力指数（RI），搏动指数（PI）则恶性肿瘤低于良性肿瘤（P〈0．01）。结论：通过二维图像及CDFI观察肿瘤形态及血流动力肇参数时原发性骨肿瘤的诊断及良、恶性鉴别诊断有很大的临床价值。

Objective To explore the diagnostic value of 2-dimentional ultrasonography and color Doppler flow imaging (CDFI) in primary bone tumor. Methods The hemodynamic parameters such as systolic maximum velocity (Vmax), diastolic minimum velocity (Vmin), resistance index (RI), and pulsatility index (PI) of intratumoral folw in 93 patients with primary bone tumors proved by histopathology were studied using 2-dimentional ultrasonography and CDFI techniques. Results The bone destruction periosteum response and soft tissue mass were essentially revealed with 2-dimentional ultrasonography techniques. The intratumoral flow features were clearly shown by CDFI. The Vmax and Vmin in malignant bone tumor were significantly higher than those in benign one (P< 0.01). RI and PI in malignant bone tumor were lower than those in benign one (P< 0.01). Conclusion Observing the features of bone tumor and hemodynamic parameters by 2-dimentional ultrasonography and CDFI has a great clinical value in diagnosing primary bone tumor and distinguishing the malignant and benign bone tumors.
