目的:探究骨肿瘤患者应用多普勒超声诊断的临床价值。方法:将我院收治的骨肿瘤患者35例作为研究对象,均采用彩色多普勒超声诊断仪对病灶进行扫查,分析超声诊断结果,比较良、恶性肿瘤的血流分级情况、超声表现、血流动力学指标。结果:35例患者超声诊断出32例,准确率为91.4%,其中良性肿瘤17例(53.1%),恶性肿瘤15例(46.9%)。良性组与恶性组相比,患者肿瘤血流分级0级比例高、III级比例低;骨皮质以未破坏、连续居多,周围软组织以无浸润为主;肿瘤血流阻力指数(RI)、舒张末期流速(EDV)指标低,和恶性组相比,差异具有统计学意义(P<0.05)。结论:对于骨肿瘤患者而言,多普勒超声诊断效果显著,能够明确肿瘤的类型、血流情况、周围软组织浸润情况。
Objective: To explore the clinical value of Doppler ultrasound in diagnosis of patients with bone tumor. Methods: Twenty-five patients with bone cancer who were treated in our hospital were studied. Color Doppler ultrasonography was used to scan the lesion. The results of ultrasonic diagnosis were compared with those of benign and malignant tumors. Hemodynamic indicators. Results: Thirty -two cases were diagnosed by ultrasonography in 32 cases, with an accuracy rate of 91.4%. There were 17 benign tumors (53.1%) and 15 malignant tumors (46.9%). Compared with the malignant group, the tumor grade of tumor grade 0 was higher than that of the malignant group, and the grade III was low. The cortical bone was predominantly undamaged and continuous with no infiltration around the soft tissue. The tumor blood flow resistance index (RI), diastolic The end-stage flow rate (EDV) index was lower than that in the malignant group (P <0.05). Conclusion: For patients with bone tumors, Doppler ultrasound diagnosis of significant effect, can clear the type of tumor, blood flow, the surrounding soft tissue infiltration.
