Does An MRI Brain Scan Have Side Effects?

Can an MRI make you feel unwell?

According to researchers at John’s Hopkins University, the magnet in MRI machines can stimulate the inner ear’s balance center, causing some patients to feel vertigo while they are inside the machine and in the minute or two after they’ve left it..

Why would a neurologist order an MRI of the brain?

MRI is used to diagnose stroke, traumatic brain injury, brain and spinal cord tumors, inflammation, infection, vascular irregularities, brain damage associated with epilepsy, abnormally developed brain regions, and some neurodegenerative disorders.

What is the most common neurological disorder?

Epilepsy is the most common serious brain disorder worldwide with no age, racial, social class, national nor geographic boundaries.

What are two major disadvantages of MRI scans?

Drawbacks of MRI scans include their much higher cost, and patient discomfort with the procedure. The MRI scanner subjects the patient to such powerful electromagnets that the scan room must be shielded.

Does an MRI show cancer?

MRI creates pictures of soft tissue parts of the body that are sometimes hard to see using other imaging tests. MRI is very good at finding and pinpointing some cancers. An MRI with contrast dye is the best way to see brain and spinal cord tumors. Using MRI, doctors can sometimes tell if a tumor is or isn’t cancer.

Can an MRI give you cancer?

“MRI” actually stands for magnetic resonance imaging, which means that these scans use only magnetic power and radio waves to create images from the information captured in the scan. Radiation is never used under any circumstances and your MRI scan will not cause cancer.

What are the side effects of brain MRI?

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. If you have allergic symptoms, tell the technologist.

Are MRI scans dangerous to health?

Extensive research has been carried out into whether the magnetic fields and radio waves used during MRI scans could pose a risk to the human body. No evidence has been found to suggest there’s a risk, which means MRI scans are one of the safest medical procedures available.

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.

What can an MRI of the brain show?

MRI can detect a variety of conditions of the brain such as cysts, tumors, bleeding, swelling, developmental and structural abnormalities, infections, inflammatory conditions, or problems with the blood vessels. It can determine if a shunt is working and detect damage to the brain caused by an injury or a stroke.

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.
