Magnetic Resonance Imaging
Magnetic Resonance Imaging (MRI) is a breakthrough in medical technology. This examination is not invasive or painful, and does not require surgical intervention or use of x-radiation. MRI generates a detailed image, which enables physicians to see, among other things, internal organs, blood vessels, muscles, joints, growths, and inflamed areas, and to diagnose physical changes in your body that cannot be detected by other means This examination enables the diagnosis of various diseases (including their early stages), and the formulation of a treatment plan for injuries and diseases. Mor Inside’s MRI apparatus (made by Phillips) is the most advanced in the field, enabling high-resolution images of superb quality to be generated.

Is it necessary to position the entire body inside the MRI scanner for examination purposes?
This depends on the region to be examined, because it has to be in the center of the tunnel. For example, for a knee examination, the knee must be placed in the center of the tunnel, while the upper part of the body would be outside the tunnel.

In some thoracic and abdominal examinations, patients are required to hold their breath for 10-25 seconds in order to avoid blurring the picture.
