There is a tremendous difference in elasticity between normal and pathological tissues. Noninvasive evaluation of the elasticity of human tissues would be valuable for clinical practice. Magnetic resonance elastography(MRE)is a recently developed noninvasive imaging technique that can directly visualize and quantitatively measure tissue elasticity. This article reviewed the MRE technique and its current status. 展开更多

Objective Real-time ultrasound elastography(US-E) is a helpful tool in diagnosing thyroid nodules.This study aims to evaluate thyroid solid nodules,to establish the accuracy of US-E in providing information on the nature of these nodules,and to assess the clinical value of elasticity scores(ES) and strain ratio(SR) in differentiating thyroid solid nodules and to explore its distribution characteristics using pathological analysis as reference. Methods Traditional ultrasonography and US-E were performed on 131 thyroid solid nodules(99 benign ones and 32 malignant ones) in 120 patients(78 females and 41 males).Three radiologists evaluated the nodules based on a four-degree elasticity scoring system.The nodules were classified according to the ES as soft(ES 1-2) or hard(ES 3-4).The SR was calculated online. Results The sensitivity and specificity of the ES for thyroid cancer diagnosis were 78%and 80%,respectively.SR values > 2.9 used as a standard to distinguish benign from malignant nodules had a sensitivity of 87%and a specificity of 92%.The SR of the benign lesions was 1.64±1.37,which was significantly different from that of malignant lesions,which was 4.96±2.13(P<0.01). Conclusions Both the ES and SR were higher in malignant nodules than those in benign ones.Real-time US-E was a useful index in the differential diagnosis of thyroid solid nodules.It can provide quantitative information on thyroid nodule characterization and improve diagnostic confidence. 展开更多
