目的本文主要研究颌面颈部间叶组织恶性肿瘤,19例的超声诊断要点及误诊原因分析,旨在提高超声诊断符合率。方法使用Logiq-700、DU-5、DU-6超声诊断仪,探头频率8~14MHz。超声检查主要观察肿块的形态、质地、内部回声、后方回声、境界和包膜。CDFI观察肿瘤的内部和边缘有血流信号。频谱多普勒测得典型的动脉频谱,静脉频谱和非典型的频谱。结果超声诊断恶性肿块或有恶性可能的肿块13例,符合病理学诊断为68.4%。作者认为诊断的依据是来自灰阶声像图特点,也就是我们看见图像时就观察肿块的各项特点。这样在边检查边思考并结合临床医学知识得出诊断。结论综上所述,超声影像学对于颌面颈部肿瘤的检出率极高,并能作出极有价值的诊断。且与其它影像学诊断相比具有一定的优势,因此作者认为对颌面颈部的肿瘤诊断超声是首选检查方法。
Objective This article mainly studies malignant tumors of maxillofacial and cervical mesenchyme, 19 cases of the main points of ultrasound diagnosis and misdiagnosis reasons, aimed at improving the coincidence rate of ultrasound diagnosis. Methods Logiq-700, DU-5, DU-6 ultrasonic diagnostic apparatus were used. The probe frequency was 8 ~ 14MHz. Ultrasound examination of the main observation of tumor morphology, texture, internal echo, echo back, realm and envelope. CDFI observed blood flow inside and outside the tumor signal. Spectrum Doppler measured typical arterial, venous, and atypical spectra. Results Ultrasound diagnosis of malignant or malignant lumps in 13 cases, in line with the pathological diagnosis of 68.4%. The author believes that the basis of diagnosis is from the gray-scale sonographic features, that is, when we see the image to observe the characteristics of the tumor. This side of the examination while thinking and combined clinical knowledge derived diagnosis. Conclusion To sum up, ultrasound imaging for the detection of maxillofacial neoplasms is extremely high, and can make a valuable diagnosis. And compared with other imaging diagnosis has some advantages, so the author believes that the diagnosis of maxillofacial neoplasms is the preferred method of examination of the tumor.
