小波变换的图像增强技术与CT扫描在腰椎间盘突出症定位诊断中的对比研究

目的探讨小波变换图像增强技术（ＷＴＩＥ）定位诊断腰椎间盘突出症在临床上的应用价值。方法利用ＷＴＩＥ对１００例腰椎间盘突出症住院病人的脊柱Ｘ线片进行处理，获得腰椎间盘突出节段椎管局部的额状面数字图像，根据该图像显示椎间盘突出的形态，定位诊断腰椎间盘突出症，并与ＣＴ及手术所见进行对比。结果腰椎管局部感兴趣区的额状面数字图像定位诊断腰椎间盘突出症阳性率８５２％，ＣＴ阳性率７７６％。结论ＷＴＩＥ简便实用，定位诊断正确率高，有临床推广应用价值。

The Localization Diagnosis of Lumbar Disc Herniation by the Wavelet Transform Image Enhancement Science to Give CT1Contrast Study and Research

Objective Probe into the localization diagnosis of the lumbar disc herniation using wavelet transform image enhancement science(WTIE) by clinical to make use of value.Methods The X ray films of the hundred cases with lumbar disc herniation were processed by WTIE.The digital images of the spinal canal at the site of lumbar herniated disc on coronal plane were acquired by which the morphology of the herniated disc was visualized to diagnose lumbar disc herniation.The diagnostic result was compared with that of the CT and its operation.Results The intrinsic hidden information on X ray film was found.The rate of correct localization diagnosis using the digital image on the coronal plane was up to 85.2%,CT scanning was up to 77.6%.Conclusion WTIE was a simple and easy and practical technique in the localization diagnosis of lumbar disc herniation.It deserves further studies and clinical popularization.
