Soft Tissue Reporting and Data System
Soft Tissue-RADS is an ACR work-in-progress framework for standardized reporting of soft-tissue lesions on MRI, extending the reporting-and-data-system model into a domain long dominated by narrative description. The goal is to reduce variability in how the same soft-tissue mass is described and to link findings to consistent management. Like Bone-RADS, it is approved by the ACR RADS steering committee for development but not yet supported by enough evidence for routine use — a good “one to watch” entry for a news-driven reference site.
Introduced to extend the RADS model to soft-tissue MRI lesions, reducing variability in description and linking findings to consistent management. Approved for development by the ACR RADS steering committee; not yet for routine use.
Soft Tissue-RADS accuracy for distinguishing benign from suspicious soft-tissue tumors on MRI was 82% vs 61% for qualitative reads (p<0.001), with good inter-reader agreement (κ=0.79) in a 150-patient validation by expert MSK radiologists.
