A test that uses a magnetic field and pulses of radio wave energy to make pictures of organs and structures inside the body. In many cases, MRI gives different information about structures in the body than can be seen with an X-ray, ultrasound, or computed tomography (CT) scan. MRI also may show problems that cannot be seen with other imaging methods.
MRI is done for many reasons. It is used to find problems such as tumors, bleeding, injury, blood vessel diseases, or infection. MRI also may be done to provide more information about a problem seen on an X-ray, ultrasound scan, or CT scan. Contrast material may be used during MRI to show abnormal tissue more clearly. An MRI scan can be done for the:
Our clinic offers its clients MRI service of all organs possible. MRI in our medical centre has a big amount of advantages:
Many patients require sedation for MRI because of the need to minimize movement during potentially long scanning times and the noisy and claustrophobic environment of the scanner. Typically, sedation is made in the following cases:
The magnetic field created by the MRI machine may interfere with the functioning of electrical devices including heart pacemakers and neurostimulators. Persons with implanted electrical devices must not enter the scanner room. During the examination, there is also a risk of temperature elevation in the adjacent tissues in patients with implanted metal parts, including hip replacements, vascular clips or foreign bodies.
Metal hip replacements, sutures or foreign bodies in other sites are relative contraindications to the MRI. The first trimester of pregnancy is also a relative contraindication against the examination. The radiologist makes the final decision as to whether to proceed with the examination. In case of any doubts, please contact the Manager of the MRI Laboratory via telephone.
As a rule, MRI procedure does not require special preparation. The exception is contrast MRI. Contrast MRI of the abdomen can be performed in fasting state only or 2 hours after a meal.
The MRI machine looks like a long narrow tube that has both ends open. You lie down on a movable table that slides into the opening of the tube. A technologist monitors you from another room. You can talk with the person by microphone.
The MRI machine creates a strong magnetic field around you, and radio waves are directed at your body. The procedure is painless. You don't feel the magnetic field or radio waves, and there are no moving parts around you.
An MRI can last anywhere from 15 minutes to more than an hour.
