MRIMagnetic resonance imaging (MRI) combines an advanced computer system, radio waves and a strong magnetic field rather than x-rays to provide remarkably clear and detailed pictures of internal organs and tissues. It is one of the safest, most comfortable imaging techniques available for the diagnosis of a broad range of conditions in all parts of the body.

Overlake Hospital Medical Center Outpatient Imaging offers two types of MRI exams: high-field MRI and large opening, short bore high-field open MRI. High-field MRI produces the highest quality images in the shortest time, making it the system of choice whenever possible. To accommodate larger individuals (up to 550 pounds), claustrophobic or special needs patients, the large opening, short-bore MRI system uses a wide and short tunnel magnet that greatly reduces or removes the “tunnel effect."

An MRI exam is safe, simple and painless. However, please notify us for further instructions if:

  • You are pregnant or could be pregnant.
  • You have a pacemaker, defibrillator, heart valve, cochlear implant or neurostimulator.
  • You have a history of metal in the eyes.

Pacemakers, defibrillators and cochlear implants are contraindications to MRI scanning due to the high magnetic field used.

Other implant devices such as hip or knee prosthesis, surgical clips or pins and cardiac stents that have been in place for more than six weeks pose no problem.

Some heart valves, aneurysm clips and neurostimulators are not safe. Bring the implant certificate with you so the technologists can refer to the manufacturer’s information about MRI compatibility.

Preparation for your procedure will depend on the type of MRI being done and the body area being scanned. Specific preparations are listed below with links to the MRI Exam Guidelines for general procedural information.

Abdomen/Liver/Pelvis MRI
Abdomen/Pelvis MRI
Chest MRI/MRA
Heart MRI
Head MRI
Lower Extremities MRI

Abdomen/Liver/Pelvis MRI
Evaluates the liver, spleen, kidneys, adrenal glands and pancreas.
Abdomen/Liver/Pelvis MRI
Abdomen/Pelvis MRI
Evaluates the uterus, cervix and ovaries in women; evaluates the prostate, bladder, penis and scrotum in men.
Abdomen/Pelvis MRI
Chest MRI/MRA
Assesses structures within the chest cavity, including the heart and lungs. Chest MRI detects and stages cancer of the lungs, breast and other tissues. It is also used to evaluate blood vessels and lymph nodes. A special form of MRI called magnetic resonance angiography (MRA) can demonstrate narrowing of the coronary arteries or an actual blockage by fatty deposits or a blood clot, which often precedes clinical heart disease.
Chest MRI/MRA
Heart MRI
Assesses heart function and structure.
Heart MRI
Head MRI
Evaluates brain function and abnormalities; used to diagnose stroke, tumor or other neurological conditions.
Head MRI
Lower Extremities MRI
Evaluates joints (such as knee, shoulder or ankle) and soft tissues to detect ruptured ligaments, damaged cartilage or small fractures that can't be seen on regular x-rays.
