Magnetic resonance imaging is a powerful noninvasive means by which to study the integrity of silicone breast implants. Silicone has a unique MR frequency and long T1 and T2 relaxation times that allow for several MR sequences to provide excellent diagnostic images. This unit presents a basic protocol for imaging of silicon breast implants.
