Tid bits 3 It is always a good idea to start with a radiograph of the area in question. Proceed with MRI if you are concern with ligaments or soft tissue problems, occult fracture or characterization A CT if you are more concern with bony problems Sometimes you need both. 3 It is always a good idea to start with a radiograph of the area in question.
