声脉冲辐射力成像对乳腺肿瘤的诊断价值
Diagnostic value of acoustic radiation force impulse imaging in breast tumor
摘要
Abstract
Objective To evaluate the differentiation diagnostic value of acoustic radiation force impulse imaging (ARFI) technique to the benign and malignant breast lesions .Methods A total of 87 breast masses in 84 patients were selected and per‐formed the routine ultrasound ,virtual touch imaging(VTI) and virtual touch quantification(VTQ) examination .The shear wave ve‐locity was obtained .The average optical density of the tumor was obtained by processing the VTI images by using the image J soft‐ware .The pathological results served as the gold standard and the ROC curve was drawn .Finally ,the significance of ARFI was e‐valuated .Results All 87 pathologically verified breast tumors included 31 malignant lesions and 56 benign lesions .In malignant le‐sions ,there were 21 lesions with VTQ value≥3 .49(threshold value) and 10 lesions with VTQ value<3 .49 .In benign lesions ,there were 3 lesions with VTQ value≥3 .49 and 53 lesions with VTQ value<3 .49 .In malignant lesions ,there were 28 lesions with the mean optical density value≥202 .25(threshold value) and 3 lesions with the mean optical density value<202 .25 .In benign lesions , there were 6 lesions with the mean optical density value≥202 .25 and 50 lesions with the mean optical density value<202 .25 .There were statistically significant differences in the shear wave velocity measured by VTQ and average optical density measured by VTI between malignant and benign lesions(P=0 .000) .The sensitivity ,specificity ,positive predictive value ,negative predictive value ,ac‐curacy rate and Youden index of conventional ultrasound were 96 .8% ,67 .8% ,62 .5% ,97 .4% ,78 .2% ,0 .645 ,respectively ;which for ARFI were 93 .5% ,98 .2% ,96 .7% ,96 .5% ,96 .6% and 0 .917 ,respectively .Conclusion The ARFI is superior to the conven‐tional ultrasound in the specificity and accuracy rate in diagnosing breast tumor .关键词
