Musculoskeletal CT and MRI protocols:
Radiographs are recommended prior to MRI as somethings cannot be seen on MRI such as chondrocalcinosis, calcific tendonitis and lesion margin evaluation.
- MRI shoulder: Chronic shoulder pain, concern for rotator cuff, labral tears, or soft tissue problems.
- CT shoulder: Acute trauma or Non-MRI compatible patients. Looks mainly at bones. Can be performed with arthrogram.
- CT hip: Acute trauma
- MRI Pelvis: Without contrast. To look for fracture, osteonecrosis, labral tears. If concern for mass or osteonecrosis use contrast.
- CT pelvis: Acute trauma
- MRI Knee: Without contrast. Best for most knee problems.
- CT knee: Acute trauma, can be considered for chronic pain but of limited value.
- CT Ankle: Acute trauma.
- MRI ankle: Chronic pain. Concern for ligament or tendon injury. Osteonecrosis of the talus.
- MRI tibia/fibula: Shin splints/fracture without contrast. Soft tissue mass/osseous mass perform with contrast.
- MRI SI joints/Sacrum: Sacral pain/SI joint Pain
