In brief
This animal study evaluates combining shear-wave elastography with Doppler ultrasound to improve differentiation between testicular torsion and epididymo-orchitis. Using a rat model, researchers measured tissue stiffness and blood flow at different time points to assess whether dual-modality imaging reduces diagnostic errors in acute scrotal emergencies.

Background and aim
Shear-wave elastography (SWE) is a noninvasive ultrasonographic procedure that uses sound waves to measure tissue elasticity. Testicular torsion (TT) is an important emergency condition that is frequently misdiagnosed as epididymo-orchitis (EO). Doppler sonography (DS) is currently associated with false-positive and false-negative results owing to a variety of reasons, although its sensitivity and specificity for the differential diagnosis of TT and EO remain high. The aim of this study was to determine the efficacy of SWE performed simultaneously with DS for differentiating between TT and EO.
Materials and methods
The study included 32 male Wistar albino rats weighing 300–350 g. The rats were randomly divided into the following groups of 8 each: 1. Control group; 2. Sham group; 3. TT group; 4. EO group. The TT group was divided into subgroup 1 (SE and DS performed 1 h after inducing TT) and subgroup 2 (SE and DS performed 24 h after inducing TT). Scrotal SWE and DS were performed simultaneously in all the rats.
Results
There were significant differences in velocity and stiffness between the control group and TT subgroup 1 (P
