What should you know about an MRI shoulder with contrast?

MRI creates detailed images of muscles, tendons, cartilage, ligaments, bone and fluid. Contrast is a substance given through a vein, or in some shoulder studies placed into the joint by injection, depending on the clinical question. It can make active inflammation, a small tear, scar tissue or the edges of a joint problem more visible. The radiologist chooses sequences and describes the findings; contrast does not automatically mean that a serious condition has been found.

Tell the imaging team about kidney disease, previous contrast reactions, implanted devices, metal fragments, pregnancy or possible pregnancy. A [3T MRI Scanner](/technology/3t-mri-scanner/) is one type of scanner; the strength of the scanner is only one part of image quality and clinical usefulness.

Follow the imaging centre’s instructions about eating, drinking and medicines. Remove metal objects and tell staff if enclosed spaces make you anxious. During the scan, stay still and follow breathing or positioning instructions. Afterward, ask when and how the report will be reviewed. The result may support rehabilitation, an injection, observation or a surgical discussion, depending on the tendon, labrum, cartilage or joint finding. A scan can help plan procedures such as [Rotator Cuff Repair](/treatments/sports-and-arthroscopic-surgery/rotator-cuff-repair/), but the decision also depends on strength, function, symptoms and examination.

Tell the imaging team immediately if you develop breathing difficulty, facial swelling, widespread itching, faintness or severe dizziness after contrast. Seek urgent assessment for a shoulder that is suddenly deformed, a hand that becomes cold or numb, or severe pain after an injury. These symptoms need attention even if the MRI appointment or report is still pending.

Ask why contrast is recommended, whether it will be injected into a vein or the joint, and what finding the scan is meant to clarify. Ask how your medicines or kidney health affect preparation, when the report will be available, and which result would change treatment. If surgery is discussed, ask how the MRI finding relates to your shoulder function.
