An MRI differs from a CAT scan (also called a CT scan or a computed axial tomography scan) because it does not use radiation..

How long does it take to get MRI results private?
When will I get my MRI scan results? Results will usually be sent to the doctor who referred you within two to seven days of your MRI scan.
Does your whole body go in for a brain MRI?
A short-bore system only scans the necessary part of the body, and allows the rest of the body to be outside of the magnet. For this type of scanner, only the upper part of your body would be inside the tube for a brain MRI. With an open MRI, all sides of the machine are open.
Can you sleep during an MRI?
For those examinations, we will not allow you to fall asleep. However, there are many other types of MRI examinations that do not require you to follow commands. For those examinations, our efforts to make our patients comfortable may cause them to nap through their exam.
Are there side effects after an MRI?
On very rare occasions, a few patients experience side effects from the contrast material. These may include nausea, headache and pain at the site of injection. It is very rare that patients experience hives, itchy eyes or other allergic reactions to the contrast material.
How accurate are MRI scans of the brain?
In our series of 112 patients with meniscal pathology, MRI scanning was 90.5% sensitive, 89.5% specific and 90.1% accurate. Conclusions: False positive MRI scans may lead to unnecessary surgery.
How long does brain MRI take?
As pictures are taken, you must hold very still, and in some cases, hold you breath. The technologist is always able to see and hear you during the exam. The MRI exam takes approximately 45 minutes.
What can I expect from a brain MRI?
The test normally takes 30 to 60 minutes. You may receive a contrast solution, usually gadolinium, through an IV to allow the MRI machine to see certain parts of your brain more easily, particularly your blood vessels. The MRI scanner will make loud banging noises during the procedure.
Can MRI results be seen immediately?
This means it’s unlikely you’ll get the results of your scan immediately. The radiologist will send a report to the doctor who arranged the scan, who will discuss the results with you. It usually takes a week or two for the results of an MRI scan to come through, unless they’re needed urgently.
Is it normal to be tired after an MRI?
Gadolinium, a rare earth metal, is used to as a “contrast agent” to improve the quality of images in around 30% of MRI scans. But some patients claim they have experienced debilitating pain, chronic fatigue and involuntary muscle spasms after being injected with the chemical.

Who can read MRI results?

The machine provides a view inside the body, but it is up to human eyes and the judgment of the radiologist to analyze what the machine has recorded.
Can you wear jeans in an MRI?
Please wear comfortable clothing. Cotton, polyester, and wool are best. Don’t worry about the snaps or zippers on pants, as that metal can be allowed into the scanning facility. If you have questions about these procedures, please feel free to contact the study coordinator.
