高低频超声对阑尾病变的病理—影像学对比研究

Contrast Study on Pathology and Imageology of Appendical Lesions between Bigh Frequency Ultrasound and Low Frequency Ultrasound

目的 探讨阑尾病变的超声图像特征及超声对阑尾病变的诊断价值 .方法 应用低频超声 (简称低频 )及高频超声 (简称高频 )对 87例可疑阑尾病变进行检查并诊断 ,全部经手术与病理证实 .结果 阑尾病变的超声诊断符合率 :低频为 4 2 .3% ,高频为 94 .1% .结论 高频对阑尾病变的显示率明显高于低频 。

Objective To investigate the features of ultrasound images and evaluate the diagnostic value of ultrasound in appendic lesions. Methods Eighty-seven doubtful appendic lesions were examined and diagnosed with low and high frequency ultrasound respectively. All these cases were verified by pathology after operation. Results The diagnostic accurate rate of high frequency ultrasound in appendic lesions was 94.1% and that of low frequency ultrasound was 42.3%. Conclusions The display rate of high frequency ultrasound is higher than that of low frequency ultrasound in appendic lesions. The high frequency ultrasound can intuitively display appendic lesions which puovide an objective diagnostic basis for colinic.
