A grading system for muscle strains based on MRI findings and anatomical site.
BAMIC grades muscle injuries 0-4 by MRI appearance (extent of edema/hemorrhage and fiber disruption) and assigns a letter (a/b/c) for anatomical location (myofascial, musculotendinous, or intratendinous). It was developed to standardize terminology and prognosis in athletic muscle injuries, particularly hamstring strains. Grading reliability and correlation with return-to-play time remain debated, with some studies finding only moderate inter-rater agreement.
