ABSTRACT
PurposeTo evaluate the significance of ultrasonic elastography strain ratio, MRI and the combination of both in diagnosis of breast tumor.Materials and MethodsFifty-four cases with single breast tumor underwent preoperative ultrasound elasticity imaging and MRI. Accuracy of ultrasound elastography strain rate ratio (SRR) of the tumor and surrounding normal breast tissue was measured by quantitative ultrasound elastography, and its combination with MRI were analyzed. ResultsThere was signiifcant differences on SRR between the benign group and the malignant group (2.24±1.28vs 4.96±1.73, t=2.648,P0.05). Combined both had higher diagnosis accuracy when compared with SR and MRI separately (χ2=6.000 and 3.967,P<0.05).Conclusion Ultrasonic elastography strain ratio is accurate and objective in differentiating benign from malignant breast tumors. It is a valuable quantitative index in clinical practice. Moreover, SRR combined with MRI can reduce the misdiagnosis rate.
