The heart and vascular system play an important role in nourishing the organs in the body. Using an MRI scan to check the activity of the heart and blood vessels is called magnetic resonance angiography (MRA). An MRI technique can also be used to measure heart function or how much blood the left ventricle can pump out of the body.

Magnetic resonance imaging, or MRI, is used to evaluate problems with the brain, neck, and spinal cord, or to help doctors evaluate problems in a person's chest, heart, abdomen, joints, or blood vessels. There are several different types of MRI scans, and they are used depending on the condition that the person needs to be examined, treated, and monitored.

Brain MRI helps to evaluate brain structures better and in more detail than other imaging methods, and this technique can also provide functional information (fMRI) about brain activity areas. In particular, brain MRI can detect cerebral infarction at an early stage, assess cerebral perfusion, thereby helping to diagnose early and intervene promptly to save the brain tissue areas that can still recover.

Prolonged headaches are a fairly common medical condition in today's society. This is a symptom of many causes, in particular it can be a manifestation of cerebral aneurysm. "If not detected early and treated promptly, when a cerebral aneurysm ruptures, it will lead to disability or death for the patient" - Dr. Ton That Tri Dung, Head of the Department of Examination and Internal Medicine, Vinmec Da Nang International General Hospital emphasized in an interview about the risks of this disease.
