Magnetic resonance imaging (MRI) already has a number of indications in exploration of the mediastinum, the most frequent of which being exploration of vascular pathologies facilitated by visualization of vascular lumina without need for a contrast medium, MRI can provide detailed information concerning the size, relations and wall thickness of these vessels ans sometimes of aneurysmal thrombosis. It also makes it possible to study aortic dissections and venous diseases of the mediastinum. As regards mediastinal masses, MRI complements computerized tomography (CT): it is better than the latter to distinguish vascular relations and it provides aetiological arguments based on the intensity of T1 and T2-weighted signals.

UI	MeSH Term	Description	Entries
D008279	Magnetic Resonance Imaging	Non-invasive method of demonstrating internal anatomy based on the principle that atomic nuclei in a strong magnetic field absorb pulses of radiofrequency energy and emit them as radiowaves which can be reconstructed into computerized images. The concept includes proton spin tomographic techniques.

D008482	Mediastinum	A membrane in the midline of the THORAX of mammals. It separates the lungs between the STERNUM in front and the VERTEBRAL COLUMN behind. It also surrounds the HEART, TRACHEA, ESOPHAGUS, THYMUS, and LYMPH NODES.

D001994	Bronchogenic Cyst	A usually spherical cyst, arising as an embryonic out-pouching of the foregut or trachea. It is generally found in the mediastinum or lung and is usually asymptomatic unless it becomes infected.
