FAQ

What is MRI?

Magnetic resonance scanning or imaging (MRI) is a revolutionary technique that is capable of getting accurate, detailed images of almost any organ in the body, without X-ray or the injection of a radioactive substance. The procedure can yield detailed images in three dimensions. MRI is generally regarded as the most significant diagnostic technique since the discovery of the X-ray in 1895.

What are the diagnostic advantages of MRI?

MRI images can result in an early, accurate diagnosis, sometimes eliminating the need for other diagnostic tests and exploratory surgery.

What can be seen with MRI?

MRI can image bones, tissues, and organs. For example, cancer, tendon damage and multiple sclerosis in its earliest stages can be detected and evaluated with MRI

Can everyone be imaged on an MRI system?

Almost everyone. However, there are some situations that might make a scan inadvisable. These include patients who have pacemakers or metal implants such as intracranial aneurysm clips. Other metal objects may cause problems as well. All of these situations should be discussed with the physician and/or technologist prior to a scan.

Can a pregnant woman be scanned?

Yes, if the physician feels that the situation warrants it. Scanning during the first trimester, however, is generally not advised.

What does the patient do during an MRI scan?

The patient simply lies quietly on the scanning bed.

What does an MRI exam feel like?

The test is painless and non-invasive. There is no pressure, no probing. An MRI scan is one of the most comfortable tests a patient can have.

Does MRI have any side effects?

There are no known biological, long-term side effects associated with an MRI exam.

How is MRI different from X-ray?

Unlike MRI, X-ray uses ionizing radiation and is less effective at imaging soft tissue and organs.

Does the patient have to do anything special before the exam?

No. The patient can eat and drink normally, and take any required medication. The patient can even drive to the test and in most cases can return to normal activity on the same day.

How long does an MRI exam take?

The average exam takes between 30 and 60 minutes.
