MRI stands for Magnetic Resonance Imaging. The MRI scanning machine uses a strong magnetic field and radio waves to create accurate and detailed images of the body’s internal organs and structures utilizing a computer.
This advanced imaging technique can help detect injuries or abnormalities of the joints, such as back pain, abnormalities of the brain and spinal cord, tumors, cysts, and other abnormalities in various parts of the body, certain types of heart problems, diseases of the abdominal organs, causes of pelvic pain in women, and other gynecological issues.
Patients need little or no preparation. Unless otherwise instructed, you can eat normally and take your usual medications.
You will be asked to remove all metallic jewelry as metal interferes with the imaging. In the MRI room, the technologist will help you lie down on a cushioned table in a comfortable position. The table will slide into the magnet area. The technologist will give you instructions through an intercom from the adjoining room where the scanning process is monitored. You can also speak to the technologist.
The scanner may make loud noises when it operates. At some points, you may be asked to briefly hold your breath as the scan is taken. To enhance the appearance of the images, patients are sometimes injected with intravenous (IV) contrast liquid.
The average time taken for the scan ranges from 25 to 30 minutes. After the scan, you can go about your normal activities.
In contrast to closed MRI machines, open MRI machines such as the Hitachi Airis II do not enclose the patient. The open MRI system allows easy access from all sides and the patient can be positioned in a way that provides the best image quality. Open MRI prevents claustrophobia and is comfortable for patients of all ages and sizes.
