目的通过与CT、MRI的对照,探讨高频超声对周围神经鞘瘤的诊断价值及其临床应用。方法对11例经手术及病理证实周围神经鞘瘤的患者,分别应用高频超声观察其形态学特征,应用彩色多普勒血流显像观察其内部血供情况,并应用CT、MRI进行对比研究。结果本组11例患者中,高频超声诊断11例,检出率100%,彩色多普勒超声诊断神经鞘瘤7例,诊断准确率64%。结论高频超声联合彩色多普勒超声检查,具有简便、无射线损害、价廉,可以动态及重复检查,在周围神经鞘瘤诊断中具有重要价值。
Objective To investigate the diagnostic value and clinical application of high frequency ultrasound in peripheral schwannoma by contrast with CT and MRI. Methods 11 cases of peripheral nerve sheath tumor confirmed by surgery and pathology were observed by high-frequency ultrasound morphology, color Doppler flow imaging was used to observe the internal blood supply, and CT, MRI contrast the study. Results Among the 11 patients, 11 cases were diagnosed by high frequency ultrasound and the detection rate was 100%. Seven cases of schwannoma were diagnosed by color Doppler ultrasonography. The diagnosis accuracy was 64%. Conclusion High-frequency ultrasound combined with color Doppler ultrasound has the advantages of simplicity, no radiation damage, low cost, dynamic and repeated examination, and is of great value in the diagnosis of peripheral schwannoma.
