MRI

MRI (magnetic resonance imaging) is a diagnostic procedure that combines a powerful magnet, radio waves and computer technology to provide detailed images of tissues, muscles, nerves and bones. Because MRI uses magnetic force and radio waves to create images, there is no radiation exposure during the procedure. MRI is often used instead of CT to study soft tissues or organs because bones do not obscure the organs and soft tissues as they do with CT imaging.

The GE 1.5 Tesla Echospeed MRI unit features a shorter tunnel and a wider bore design offering a more spacious, less claustrophobic feeling and easier access for patients with limited mobility. The scanner also has a higher weight capacity than the previous unit. The addition of this new MRI machine to Paul B. Hall Regional Medical Center’s radiology department expands access to diagnostic imaging that supports a complete range of clinical applications, including neurology, orthopedics, body imaging and angiography.

Advanced technology and imaging capability

MRI can be used to assess everything from ruptured discs in the spine to detecting brain tumors and vascular diseases through techniques such as:

• Angiography (MRA) evaluates blood flow, or detects brain aneurysms or blood vessel abnormalities. It is used to visualize renal, carotid and vertebral arteries, or examine the aorta for aneurysm.
• Perfusion and diffusion scanning examines blood flow through tissues to evaluate strokes.
