B超与彩色多普勒闪烁伪像检测肾结石的差异性研究
To investigate the difference between B-mode ultrasonography and color Doppler twinkling artifact for detection of kidney stone
摘要
Abstract
Objective:To compare the detective effect between color Doppler twinkling artifact and B-mode ultrasonography for kidney stones in order to develop an ultrasonic model that can more easily and more accurately detect kidney stone.Methods: 9 patients with kidney stone who were confirmed by CT scan in recently were selected to accepted two methods (color Doppler twinkling artifact and B-mode ultrasonography) to detect kidney stone. The video fragments of upper pole, interpolar and lower pole were created by three radiologists and the results were diagnosed by them.Results: In dual kidneys of the nine patients, 32 stones with average size of (8.9±7.5) mm were found. The sensitivity, specificity, positive predictive value and negative predictive value of the B-mode ultrasonography were 71%, 48%, 52% and 68%, respectively, while those of color Doppler twinkling artifact were 56%, 74%, 62% and 68%, respectively.Conclusions: In the detection of kidney stones, B-mode ultrasonography is more sensitive when is used alone, but color Doppler twinkling artifact has more high specificity. The color Doppler twinkling artifact should be applied in more clinical practices, and a new commercial ultrasonography mode that used basic acoustic difference and is special for detection of kidney stone should be researched and developed so as to improve the detection of kidney stone.关键词
