Basic MRI Musculoskeletal Anatomy
Musculoskeletal MRI Indications • • • Sport related injuries Mensical abnormalities Osteonecrosis Bone marrow abnormalities Soft tissue masses
Musculoskeletal MRI Advantages • • Superior soft tissue contrast Mutliplanar Non invasive No ionizing radiation
Musculoskeletal MRI Disadvantages • Expensive • Limited availability • Claustrophobia
Musculoskeletal MRI Disadvantages • Artifacts (Metal foreign objects) • Relatively long examination • Calcifications
FAT Bone marrow Blood Contrast
Air Cortical bone Tendon Ligament Blood vessels
Muscles Hyaline Cartilage Fluid

ACL Patellar tendon
ACL
Crescent shaped fibro-cartilage. Their main functions are shock absorption and load–bearing. Lateral Meniscus Medial Meniscus
MRI the Shoulder
MRI Shoulder Indications • • • Rotator cuff tear Shoulder instability Osteonecrosis Infection Neoplasm
What is the rotator cuff? • A group of flat tendons that surround the front, back, and top of the shoulder joint like a cuff on a shirt sleeve
Rotator cuff muscles • • Supraspinatous Infraspinatous Teres minor Subscapularis

MRI of the Ankle
MRI Ankle: • • • Ligament Tendon Articular cartilage Infection Soft tissue masses Bone marrow Why?
