Overview

Magnetic Resonance Imaging (MRI) is one of the safest and most comfortable diagnostic imaging studies available. Using a strong magnetic field, radio frequency waves and an advanced image processing computer, MRI scans produce accurate images of organs, soft tissues, bone and virtually all internal body structures without exposing the patient to ionizing radiation (X-rays). Your images are stored on a specialized computer network dedicated to medical image storage called a Picture Archival and Communications System. Also known as PACS, this system allows our radiologists to interpret your images and collaborate with your physician.
Oregon Imaging Centers offers MRI scans for all parts of the anatomy. You can review information specific to your scan by selecting from the 'study type' menu in the left column.

During your visit, a patient advocate will show you to the changing area and can assist you if necessary. Our changing rooms offer secure lockers, but we encourage patients to leave valuables at home. Once changed, our patient advocate will guide you to the sub-waiting area where you will find a selection of magazines and newspapers. A staff member will notify you when it is time for your MRI Scan and introduce you to the MRI technologist.
The technologist is specially trained and certified by the American Registry of Radiological Technologists to take care of you during your MRI scan. A device called a coil may be placed around the area of your body we are scanning. Once you are comfortable, the technologist will move the table into the MRI. You will be able to speak to the MRI technologist over an intercom.
MRI scanners make a distinctive knocking and buzzing sound as it acquires images. These sounds are normal and may last a few minutes. Some patients request ear plugs or you may prefer to wear headphones. We have a variety of music choices you can select from or you may bring a CD and ask the technologist to play it for you. Some patients also find it comforting to wear goggles or prism glasses, which can help patients who might feel claustrophobic.
Most MRI studies require an IV injected contrast agent called gadolinium to help the radiologist visualize certain tissue or blood vessels. Some patients describe a metallic taste or tingling sensation after the injection. This is normal and usually subsides quickly.

- A small percentage of patients with tattooed eyeliner experience temporary skin irritation in association with the MRI.
- A sub-specialized radiologist will interpret your images and prepare a diagnostic report for your physician.
- Results are usually made available to your physician in two or three days. If outside comparison studies are required, it may take longer for your results to be made available.
- Your physician will determine how the radiologists' report can be used to develop a treatment plan and speak with you about your results.

A breast MRI is often performed for patients who have had an abnormal mammogram, a strong family history of breast cancer, discovered a palpable mass or have breast implants that interfere with receiving a standard mammogram. A bilateral MRI breast study is indicated for mastectomy patients to allow the radiologist to evaluate the lymph nodes, chest wall, residual tissue and post surgical changes.
