Magnetic resonance imaging (MRI) is a test that uses a magnetic field and pulses of radio wave energy, instead of radiation or x-rays, to make pictures of organs and structures inside the body. These images are then used by physicians to properly diagnose and treat you.
MRI services are available at our Main Campus and the Westford Health Center.
Because of the strong magnetic field used during the exam, certain conditions may prevent you from having an MRI.
When scheduling your appointment and prior to your exam, please alert our staff and technologist to the following conditions that may apply to you. The radiology staff will let you know whether you can have the MRI exam and whether the exam needs to be modified for your particular condition.
- History of kidney problems
- Skin tattoos
- Neurostimulators (TENS-unit)
- Implanted drug infusion device, such as an insulin pump
- Exposure of metal fragments to your eye
- Artificial heart valves
- Aneurysm clips
- Cochlear implants
- Metallic implants and prostheses
- Vascular stent or stent graft
- History as a metal worker
- Shrapnel or bullet wounds
- Dorsal column stimulators
- Allergy to iodine or gadolinium
- History of diabetes
- Other conditions you believe to be relevant

Preparing for an MRI
- You can take your daily medications as you normally would, unless instructed otherwise.
- Only some MRI exams have dietary restrictions. If necessary, you will be notified of those requirements prior to your exam.
- Please bring identification and arrive at least 15 minutes prior to your exam to complete the MRI screening form.
- For those patients who feel claustrophobic or have some anxiety about having an MRI: We now have “Cinema Vision” available in the Concord location.
- In the event you feel you may need a mild sedation to help get you through the exam, please contact your physician to discuss this option prior to your appointment. If your physician prescribes a mild sedative to be taken for the appointment, plan for someone to drive you home after your exam.
What to Expect During the Exam
- Upon arrival for your exam, please check in with the Radiology receptionist. You will need to complete the MRI screening form.
- A technologist will verify your identification and the requested exam. Your screening form will be reviewed by the technologist in consultation with the radiologist if indicated.
- You will be asked to change into a hospital gown. A locker will be supplied to secure your belongings. If MRI contrast is indicated for the exam, an IV catheter will be inserted in your arm by a nurse or technologist.
After the Exam
- If an IV is used during your exam, it will be removed before you go home.
- Allergic reaction from the contrast medium is extremely rare. However, if you experience any symptoms such as rash, hives or shortness of breath, you should notify the technologist immediately if you are still at the imaging facility or call your doctor or go to the nearest hospital if you have already left the imaging facility.
- In the event that sedation is needed during your exam, someone must drive you home. You can leave the facility once you are awake and alert.
Magnetic resonance imaging (MRI) is a painless, safe and radiation-free diagnostic test that uses radio waves, magnetic fields and computer software to create highly detailed cross-sectional images of the brain, nerves, spinal cord, bones, joints, breasts, abdominal and pelvic organs.
All the studies are read by board-certified radiologists. Plus, our Picture Archival and Communications System allows doctors connected to the Emerson Hospital network to view MRI images electronically—saving vital time in your diagnosis and treatment.
