CT, ultrasound and MRI; imaging of the abdomen, pelvis, musculoskeletal system, brain and children; radiation and contrast; and which study to ask for in each case. Findings are described in words. Educational content; it does not replace a radiologist's report and is not a clinical instruction. Each study is ordered on the patient's assessment and your institution's protocols.
