彩色多普勒血流显像诊断喉癌的探讨

Preliminary Study of Diagnosing Carcinoma of Larynx Using High-frequency Ultrasound and Color Doppler Flow Imaging

目的 探讨超声及彩色多普勒血流显像诊断喉癌的应用价值及与ＣＴ检查的初步对比。方法 是经颈部直接扫查１０例喉部癌肿，观察高频声像图中肿块的大小、形态、边界、内部回声，应用 ＣＤＦＩ观察肿块内部及周边彩色血流并根据其丰富程度采用半定量法分级。 结果 得到１０例喉癌中高频超声检出９例，肿块显示率９０％（９／１０），绝大多数肿块为不均质低回声（８／９，占８９％）。肿块血流信号显示率１００％（９／９），血流丰富程度以Ⅱ级和Ⅲ级为主。结论为 超声能够清晰显示喉部正常组织结构。肿块检出率较高，结合使用ＣＤＦＩ观察肿块的血流信号，对喉癌的诊断有较高的应用价值。

Objective:To study the clinical value of using high frequence planar ultrasound and CDFI to diagnose carcinoma of larynx. Methods:We directly scan 10 cases of laryngeal tumour through cervix in order to observe the tumour's size ,sharp,limit and its inner echo. To observe the color bloodstream in the centure and side of the tumour by using CDFI. According to abundance of the tumour's blood supply.We can use the method of semi-quantitative analysis to grade it .Results: By high frequence planar ultrasound ,we can find 9 cases out of 10 cases of the laryngeal cancer, it display 90%(9/10).Most of the tumour's echo is asymmetric and low(8/9,89%).Display rate of the tumour's,blood flow signal is 100%(9/9),The abundance of the tumour's blood supply are mainly of grade Ⅱand grade Ⅲ. Conclusions: Examming through cervix, high frequence planar ultrasound can clearly display the normal structure of larynx,The discovery rate of the tumour is high .With CDFI to observe the tumour's blood flow signal ,it is of great value in diagnosis laryngeal cancer.
