Tips Medical Devices - Differences Open and Closed MRI machine - Magnetic Resonance Imaging (MRI) is a radiological scanning methods to obtain images with a magnet and radio waves.

Unlike X-rays and CT scans, MRI does not use radiation. There are three types of MRI machines that is closed, open, and stood up.

Among the three, closed and open MRI machines are most commonly used.

Closed MRI machine

Enclosed MRI machine is the oldest type of MRI machine.

During the procedure, the patient lies on a table that can be driven and fed into a large tube.

Patients were asked to lie down and not move during the test. This procedure usually takes about 30-45 minutes.

Open MRI machines

Open MRI machines have shaped configuration "C". Patients can get in and out of the side and not fully enclosed in the machine.

Regardless of these differences, the same technique performed on a closed MRI machine.


Doctors usually use a closed MRI machine as the first choice.

However, if the patient is too large for the machine's closed, open MRI machine is the next option.

Patients whose phobia of enclosed spaces (claustrophobic) can also benefit from the use of open MRI machine.


Open MRI machines can not initially produce the same quality as a closed MRI scan on the machine.

Along with the development of technology, imaging produced by an open MRI machine imaging quality is comparable with that produced a closed MRI machine.


Patients who have pacemakers or aneurysm clips should not do an MRI.

If the patient has metal implants in the body, it is recommended to talk to your doctor or the staff radiologist before the MRI.
