MRI (Magnetic resonance imaging) and MRA (Magnetic resonance angiography)
MRI (Magnetic resonance imaging) and MRA (Magnetic resonance angiography) are two of technology’s most advanced tools for today’s physician. MRI is an imaging test which looks inside your body without surgery to see the various organs and tissues. MRA is a similar imaging test that is used to see the arteries and veins in your body without the need for an invasive procedure. Neither test uses radiation that is used in both xrays and CT scans. There is no pain or known side effects. This test can give your doctor valuable information about you and your body that cannot be obtained any other way.
How should I prepare for the exam?
- No special preparation is needed prior to the MRI exam. You may continue your usual diet and medication unless your physician has instructed you otherwise.
- No physical side effects, you can drive yourself to and from the exam.
Radiology Associates offers scans on 1.5T systems. The New Port Richey location has a Siemens 1.5T Symphony and Trinity has a Siemens 1.5T shortbore/open system to help patients who suffer from claustrophobia.
What is the exam like?
- Scan times vary depending on physician order. The actual time will depend on the type of information your doctor is seeking. For your comfort, you will be asked to empty your bladder before the start of the exam.
- You will probably be asked to change into an examination gown. Your own clothing’s metal snaps or zippers might impair the exam.
- A technologist will lie you down on a contoured cushioned table which slides into the examination area.
- Relax and try to lie as still as possible. Any movement during this time will blur the image. Although the technologist does not remain in the room during the exam, they will be in constant contact with you both visually and through an intercom. When the exam is complete the technologist will help you off the table.
- The only thing you will experience during the exam is the natural rhythmic sounds of radio frequency pulses. These knocking sounds range from barely audible to quite noticeable. Headphones will be available for your comfort.
You will be extensively screened and asked about any mechanical devices: ie; pacemakers, defibrillators or other devices you may have. For a more extensive list download the following form:
