Rotator Cuff Tear: AI-Powered MRI Analysis

AI-powered rotator cuff tear detection on shoulder MRI. Grade supraspinatus, infraspinatus, and subscapularis tears by thickness and retraction. 4 AI models assess tendon integrity and muscle atrophy in parallel.

Overview

Rotator cuff tears are one of the most common causes of shoulder pain and disability. The rotator cuff comprises four muscles and tendons: supraspinatus (most commonly torn), infraspinatus, teres minor, and subscapularis. MRI is the gold standard for evaluating tear size, location, retraction, muscle quality (fatty infiltration), and associated findings. Our AI consortium provides comprehensive assessment including tear classification, Goutallier fatty infiltration grading, and measurement of tear dimensions.

Common Symptoms

Pain with overhead activities or reaching behind the back
Night pain disrupting sleep, especially lying on the affected side
Progressive weakness in shoulder elevation and rotation
Painful arc of motion between 60-120 degrees of abduction
Difficulty lifting objects away from the body
Gradual loss of active range of motion

Key Imaging Findings

Tendon discontinuity or high signal on T2 sequences indicating tear
Full-thickness tear with tendon gap and possible retraction
Partial-thickness tear involving articular or bursal surface
Muscle atrophy and fatty infiltration (Goutallier grading)
Tendon retraction measurement from the footprint
Superior migration of the humeral head suggesting massive tear
Associated biceps tendon pathology or subluxation

Frequently Asked Questions

What is the difference between a partial and full-thickness rotator cuff tear?

A partial-thickness tear involves only part of the tendon depth (articular-side, bursal-side, or intrasubstance), while a full-thickness tear extends completely through the tendon. Our AI differentiates these on MRI and measures tear extent and retraction to help characterize the injury.

What is Goutallier grading for fatty infiltration?

Goutallier classification grades muscle quality from Grade 0 (no fat) to Grade 4 (more fat than muscle). This is important for surgical planning because advanced fatty infiltration (Grade 3-4) is associated with poorer surgical outcomes. Our AI evaluates muscle quality on MRI.

Can a rotator cuff tear heal without surgery?

Some partial-thickness tears and small full-thickness tears may be managed conservatively with physical therapy. Our AI provides tear measurements and characteristics that are relevant to treatment decisions, but management should always be determined by your orthopedic specialist.
