Body Magnetic Resonance Imaging

Imaging

Using four high-field strength, state-of-the-art MRI scanners, the section of Body MRI performs and interprets MRI studies of the chest, abdomen and pelvis, such as liver mass evaluation imaging, MRCP (bile duct and pancreatic duct imaging), kidney mass evaluation, breast mass and breast implant evaluation. In addition, we perform MR angiography studies for noninvasive images of arteries of the chest, abdomen, pelvis, arms and legs.

Indications

Because MRI is highly sensitive for detection of tumors, it provides a great problem-solving tool. Lesions that have uncertain diagnoses on CT or Ultrasound exams can usually be better characterized with MRI.

The contrast materials used in MRI are also safer to use in patients with kidney disease than iodine-based contrast materials used for CT, or in patients allergic to iodine contrast.

Safety

MRI uses no X-rays and thus has no cancer risk from radiation. For the majority of patients MRI is perfectly safe. Because MRI uses very strong magnets, however, patients with implanted electronic devices or pumps, or certain metal implants like brain aneurysm clips, should not undergo an MRI. Other metal implants should be checked for safety before entering the scanning room. Speak with your doctor before scheduling an MRI exam if you have an implanted electronic or metal device.

Claustrophobia and "Open MRI"

Open MRI scanners do provide the patients with more headroom than our conventional, tube-shaped scanners, but they provide less optimal images. For this reasons, we do not use Open MRI scanners at Mayo Clinic Arizona.

Most patients who suffer from claustrophobia can undergo MRI comfortably if they first take a mild oral sedative, such as Valium. More severe claustrophobic patients can choose to be treated with stronger, intravenous sedation under the supervision of a Radiology nurse with while their vital signs are monitored.

Education

In our Body MRI fellowship program, we prepare radiologists for careers in either academic or subspecialized private practices with a balanced training program in MRI, CT, plain radiography, and procedures. Our members also participate in Mayo Foundation and national society-sponsored radiology CME courses.

Research

Our section is actively involved in clinical research, examining methods for improving imaging techniques and interpretation. We attend and present our findings at national subspecialty meetings and have published several recent articles in prominent radiology journals.
