MRI Scan - Magnetic Resonance Imaging

What is MRI?

MRI is Magnetic Resonance Imaging, a powerful diagnostic imaging tool. MRI images are produced by using two natural and harmless forces- magnetic fields and radio waves, not ionizing radiation. With the use of computers, the data acquired from your scan is transformed into two dimensional images of your body. The procedure is painless and has no known side effects. With MRI, your radiologist can see the bone and soft tissues in your body, like muscles and internal organs. These images are very sensitive in showing differences between normal and abnormal tissues.

What should I expect?

Prior to your study, we will ask you to complete an MRI questionnaire to make sure that you do not have health conditions or metallic implants that would prevent you from having a scan.

This questionnaire will ask you if you have:

  • Pacemaker
  • Brain aneurysm clips
  • Implants such as metallic plates, pins, stimulator wires, etc.
  • History of working with metals
  • History of injury during military service

MRI generally takesbetween 20 minutes and 45 minutes. For your comfort, we recommend that you empty your bladder before your scan. Our technologists will ask you to lie on a cushioned table that moves into the scanner and they will communicate with you throughout the exam.

MRI is performd in a series of imaging sequences. Before each sequence, your technologist will tell you how long the next sequence will take. MRI scans produce a tapping or banging noise that changes in frequency and volume depending on the scan type.

Some MRI scans require an intravenous injection of contrast agent. This injection enhances vessels and certain organs and vessels during the exam and is helpful to the radiologist in making the diagnosis.

When your scan is complete, you may return to your normal daily activities.

How should I prepare?

There are no special preparations or dietary restrictions prior to MRI examinations. You may continue your prescribed medications. You may be asked to change into an exam gown and take off all removal metal, i.e. earrings, body jewelry, eyeglasses, hairpins. If you are pregnant or are possiby pregnant, please inform our technologist prior to your scan.

How do I get the results?

After your MRI procedure is complete, the TRG radiologists will review your study and report the findings to your ordering physician. Follow up with your physician for scan results and care plan.

Your MRI procedure can be performed at:

MRA - Angiography

What is Angiography?

The advancement of imaging techniques such as MRI (Magnetic Resonance Imaging) has granted access into viewing the body in ways that were once thought impossible Radiologists now can perform angiograms using these techniques without a hospital visit and down time typically necessary after a standard angiogram.

Angiograms visualize blood vessels. There are many reasons why your doctor may feel an angiogram is indicated. Typical indication include pain in the legs when walking, diseases of the brain (including stroke and stroke precursors), high blood pressure, tumors, congenital abnormalities of blood vessels, and many others.

What should I expect?

The MR angiogram usually takes about 20 minutes and involve an IV injection in the arm. You can go home immediately after the procedure. The risk associated with these procedures is a very rare risk of allergic reaction to the contrast or infection at the IV site. The technologist will discuss this with you prior to the exam. You may also have questions for the radiologist, which we will be happy to answer. The images acquired during your angiogram are processed with very high speed computers and three dimensional pictures of your vessels are then available for the radiologist to review.

Breast MRI

What is MRI Breast Imaging?

MRI technology produces very detailed images of breast tissue and surrounding anatomy. It is used to determine the extent of disease in the breast, whether there is disease in the other breast and as a surgical planning tool. Breast MRI is not recommended in lieu of mammography and ultrasound but as an additional diagnostic tool. Recently, screening Breast MRI was recommended for those women who are considered to have high risk factors.

When should breast MRI be ordered?

Breast MRI is recommended for:

  • An abnormal mammogram or ultrasound
  • A positive breast biopsy
  • A recent diagnosis of breast cancer
  • Patients who have a strong family history of breast cancer and have dense breast tissue
  • A follow up evaluation for patients having chemotherapy
  • Implant patient
  • Patients who have had radiation treatments to the chest

What should I expect during an MRI Breast Exam?

Breast MRI is a series of images that are performed while you are lying face down with your breast positioned in a breast coil. Breast MRI patients require an injection of contrast agent. MRI contrast is safe however there is always the remote possibility of allergic reaction. Contrast enhances the breast tissue and helps to identify cancerous areas.

Breast MRI normally takes 45minutes-1 hour to perform. Afterward you can return to your normal daily activities.

How should I prepare for my MRI Breast Exam?

If you are still having monthly menstrual cycles, Breast MRI should be scheduled on or as close to 7th day after your cycle begins. MRI is extremely sensitive to the hormonal changes of the breast. Scheduling as such lowers the likelihood of an inaccurate result. Women taking hormone replacement may be asked to stop them for a period of time. T

If is very important that you communicate with your technologist if the following conditions apply to you:

  • You have a pacemaker
  • You have clips in your brain from surgery
  • You have worked as a metal worker
  • You have metallic plates, pins, or metal implants
  • If you have any cause for concern of a possible pregnancy
