Magnetic resonance imaging, or MRI, produces incredibly detailed cross-sectional images of your body without the use of radiation. Instead, patients enter a tube-shaped machine that creates images through sound waves and a magnetic field. Now Bristol Regional Medical Center is the only hospital in the region to offer the most powerful MRI technology available today—a new scanner system with a magnet strength of 3.0 Tesla. This painless, non-invasive procedure allows us to see superior images with greater clarity than ever before, which means shorter scan time for patients and more accurate diagnosis of a variety of diseases and injuries.
MRI and breast cancer
The American Cancer Society’s new screening guidelines support what Wellmont’s already been doing for several years—offering breast MRI to women at high risk for breast cancer. Available at the Imaging Center at Holston Valley Medical Center, breast MRI is more sensitive than a mammogram and therefore allows for better early detection. The ACS recommends that higher risk women combine an annual mammogram with breast MRI.
