MRI Breast without contrast is generally safe and well-tolerated, but there are some potential risks and limitations to consider. The test can produce false-positive or false-negative results, and it may not be suitable for patients with certain medical conditions, such as kidney disease or pacemakers. Patients may also experience claustrophobia or discomfort during the procedure. Patients should inform their healthcare provider about any medical conditions they have, such as kidney disease or a history of claustrophobia.
