MRI protocol for stroke assessment is a group of MRI sequences put together to best approach brain ischaemia. What does "MRI" stand for and how does it work? MRI stands for Magnetic Resonance Imaging. MRI uses the principle of magnetic resonance. Using the natural magnetic property of our body, the MRI machine is able to form images that help us diagnose the problem. Why is MRI such a good modality? MRI allows us to exquisitely see different parts of the body. In the brain, it allows us to differentiate between different areas. In the spine, MRI is the only modality that allows us to see the spinal cord. In joints, MRI allows us to view the internal parts of the joints, including ligaments, tendons and menisci. It also allows evaluation of various cardiac structures, as well as functional imaging of various parts of the brain. MRI does all this by sectioning the body in different planes. Just as it is necessary to slice a loaf of bread to know the quality of the slices, so also, MRI allows us to section the body to view its inner parts. Thus, the skull X-ray only shows us the outer part, whereas MRI shows us the inner parts of the brain. Where is MRI useful? All parts of the body can be scanned with MRI, but it is most useful in the brain, spine, bones, joints and the heart. It also has specific uses in other parts like the chest, abdomen and pelvis. For each part, there are specific indications or reasons for scanning. The referring doctor and the consultant radiologist are the best judges of the usefulness of MRI scanning in a specific situation and area. Are there any dangers in MRI scanning? Not ordinarily. However if you have any magnetizable items on or in your body, such as aneurysm clips, pacemakers, cardiac prostheses, metallic implants, etc. please inform us immediately, as there could be a problem related to these metallic items. What is the injection that I may receive? If necessary, you may be injected with a gadolinium-based dye to see things better.


Why is MRI BRAIN STROKE PROTOCOL done ?

Physicians use the procedure to detect or confirm abnormalities within the blood vessels in the brain, including:

  • An aneurysm, a bulge or sac that develops in an artery due to weakness of the arterial wall
  • Atherosclerosis, a narrowing of the arteries
  • Arteriovenous malformation, a tangle of dilated blood vessels that disrupts normal blood flow in the brain
  • Vasculitis, an inflammation of the blood vessels, generally narrowing them
  • A brain tumor
  • A blood clot
  • A tear in the wall of an artery, known as a vascular dissection
  • A stroke (Stroke is a clinical designation that refers to the sudden neurological deficit resulting from a cerebrovascular event. It is divided into broad categories: ischaemic stroke  (80%), haemorrhagic stroke (15%) & subarachnoid haemorrhage (5%; not always thought of as a stroke). MRI protocol for stroke assessment is a group of MRI sequences put together to best approach brain ischaemia.)

MRI BRAIN STROKE PROTOCOL Instructions

CCO:
Ask for the status of pregnancy in a female patient.Ask if the patient is on cardiac impants , metal stents , Prosthetic valves, dentures , artificial limbs , prosthetic joints , surgical clips , screws, plates , pace makers, ear implants, intrauterine devices. Ask for any history of claustrophobia. Sedation may be required to ensure relaxation of the body during the procedure.

Why is MRI BRAIN STROKE PROTOCOL ?

Magnetic resonance imaging (MRI) is a type of non-invasive test that uses magnets and radio waves to create images of the inside of the body. The magnets and radio waves create cross-sectional images of the body part, which allows doctors to check for abnormalities in the tissues and organs without making an incision. An MRI brain stroke protocol generates pictures of the brain bones (cranium), veins/arteries (grey/white matter), cranial nerves and surrounding soft tissues. MRI stroke protocol captured in scan can be stored on a device which is further printed on a film. The technology used in an MRI allows doctors to examine soft tissues without bones obstructing the view. An MRI uses no radiation and is considered a safer alternative to a CT scan.
