Abstract

Background: Ultrasound is the main evaluation modality for superficial soft tissue masses to evaluate their size, position, and relationship between the masses and the surrounding structures.
Objectives: This study's major goals were to reliably predict if a soft tissue mass was benign or malignant, to describe the mass's nature utilizing MR DWI and ultrasound elastography, and to minimize needless biopsies.
Patients and methods: South Valley University's Qena University Hospital served as the site of this cross-sectional investigation. This research comprised 30 patients who were eligible for MRI testing and ultrasound elastography between January 2021 and January 2022 and who had identified superficial soft tissue masses or clinical suspicion of having them.
Results: The majority of findings on MRI were non-enhancing masses (40%). As regard DWI findings among the studied patient, 56.7% of them were non-restricted diffusion and 43.3% were restricted diffusion.  17 benign and 13 malignant lesions recognized by DWI were correctly identified with histopathology. The DWI sensitivity was 94.4%, specificity was 100%, with accuracy of 96.7% for evaluating soft tissue masses. Strain ratio yield sensitivity of 87.1% and specificity of 89.7% with cut off level of 2.5 and AUC 0.813.
Conclusion: In terms of identifying soft tissue masses, DWI has greater sensitivity, specificity, and accuracy than US elastography.
