MR Angio Chest

This study is sometimes used to detect abnormal enlargement of the aorta in the chest, known as a thoracic aortic aneurysm. Intravenous contrast is often used, especially if aortic dissection, or tear in the wall of the aorta, is suspected. This condition is typically associated with sudden onset chest pain travelling to the back. CT angiogram is typically the first modality of choice for the evaluation of both conditions, but MR angiogram may sometimes be used, especially to follow a known aneurysm or dissection.
