Understanding Ischemic Stroke

Ischemic stroke happens when blood flow to the brain gets blocked. This stops brain cells from getting the needed nutrients and oxygen. It can cause serious brain damage or even death if not treated fast. Knowing the different stroke types helps doctors treat it quickly.

There are two main stroke types: ischemic and hemorrhagic. Ischemic strokes, caused by blood clots, make up about 87% of all strokes. Hemorrhagic strokes happen when a brain blood vessel bursts, causing bleeding. Knowing these types is key for right treatment.

In the U.S., ischemic strokes affect around 795,000 people yearly. They can cause severe disabilities. Catching an ischemic stroke early can help a lot by allowing quick action.

Symptoms of an ischemic stroke can be sudden. They include numbness or weakness on one side of the body. Other signs are confusion, trouble speaking, seeing issues, walking problems, dizziness, and losing balance.

Things like high blood pressure, heart disease, diabetes, smoking, and having mini-strokes can raise stroke risk. Knowing these risks helps in preventing strokes and understanding MRI’s role in diagnosis.

Here’s a table showing the main differences between ischemic and hemorrhagic strokes:

Clothing Guidance

Wear comfy clothes without metal when you go for an MRI. Don’t wear things with zippers or buttons. You might get a hospital gown to wear instead.

MRI Procedure Steps

The first step is talking about your health history with the technician. Then, you go into the scanning area and lie on the table. This table goes into the MRI machine. Try to stay still to get clear pictures.

1. Talking about your health history
2. Changing into the right clothes
3. Lying on the MRI table
4. Going into the MRI machine for the scan

What to Expect

The MRI machine makes a lot of noise, but you can use earplugs or headphones. If you’re scared, tell the technician. They can help make you feel better.

Common Concerns

Some people worry about metal implants or devices. Tell the technician about any metal things you have, like a pacemaker or joint replacement. Your doctor will say if you need special care.

By doing these steps and talking about your worries, getting ready for an MRI will be easier and less stressful.

Process and Duration of an MRI Scan

Getting an MRI scan is easy and well-planned. It’s made to be comfy for you, giving clear results for things like stroke diagnosis.

When you get to the imaging center, you’ll check in at the front desk. They’ll go over your details and insurance. Then, you’ll wait in a room until it’s your turn.

Next, a tech will ask you to go to a changing room. There, you’ll take off any metal and wear a hospital gown.

Then, the tech will lead you to the MRI room. You’ll lie down on the table and get comfy. You might get earplugs or headphones to block the loud MRI sounds.

Once set, the table moves into the MRI machine. You’ll need to stay still for clear pictures. MRI scans for stroke usually take 30 to 60 minutes.

• Arrival and check-in
• Changing into a hospital gown
• Positioning on the MRI table
