MAGNETIC RESONANCE IMAGING

Magnetic resonance imaging (MRI) uses interactions between radio waves, a strong magnetic field and hydrogen protons rather than x-rays to provide remarkably clear and detailed pictures of internal organs and tissues. It requires specialized equipment and expertise and allows evaluation of some body structures that may not be as visible with other imaging methods. Particular strengths include exquisite depiction of the brain, spine, joints and soft tissues although massive technological strides are establishing MRI as the gold standard for stroke, vascular, cardiac and abdominopelvic imaging.

The scanner machine is usually a long tunnel which may be a problem for claustrophobic patients. Sedation is then employed. Loud knocking and pinging sounds during scanning are suppressed with ear plugs. Intravenous gadolinium contrast may be required and is very safe. Allergic reactions are rare.

Metallic objects may be affected causing heating or movement, including heart valves, orthopedic devices, foreign bodies, pacemakers and surgical vascular clips. Today however, the only absolute contraindications are brain aneurysm clips and cardiac pacemakers. No ionizing radiation is employed and MRI is considered safe in pregnancy, but nevertheless generally avoided in the first 12 weeks of development.

Cardiac MR:

Scholtz and Partners perform highly specialized imaging of the heart at our Montana Practice. Cardiac imaging via magnetic resonance is fast becoming the gold standard for evaluation of the consequences of coronary artery disease as well as infective and infiltrative diseases that may affect the heart.

Musculoskeletal MR:

Due to our large orthopedic referral base we also perform specialized musculoskeletal imaging at specific.
