A Clinical Study Comparing the Diagnostic Performance of Assist Strain Ratio Against Manual Strain Ratio in Ultrasound Breast Elastography.

Objective: Strain ratio (SR) is a semiquantitative parameter in differentiating benign from malignant tumors in breast ultrasound elastography. Currently, SR is computed manually and, thus, user dependent. The objective of this study was to evaluate the performance of a new tool assist strain ratio (ASR) and determine how it performs compared with an expert sonologist.
