MRI and Aortography
Although these imaging modalities can be used to detect aortic dissection they are rarely used in practice [1].
MRI requires that these critically ill patients be placed on different monitoring, which is magnet-proof and doesnt allow for quick access to the patient should they deteriorate once the scan has commenced. MRI, at the moment, also takes considerable time to acquire the necessary images.
Aortography is invasive and is not performed at most hospitals. It is now rarely used as non-invasive imaging can provide the required information.
