Imaging — CT & MRI Essentials

CT: excellent for cortical bone, 3D recon. MRI: excellent for marrow, soft tissue, ligaments, cartilage. CT indications: complex fractures (pelvis, acetabulum, calcaneus). MRI indications: occult fractures, marrow edema, tumors, soft tissue injury. Contraindications: CT—radiation, contrast nephropathy; MRI—pacemaker, ferromagnetic implants.
