Magnetic resonance imaging-guided percutaneous cryoablation of hepatocellular carcinoma in special regions.

Abstract

MR-guided percutaneous cryoablation using optical navigation is a safe and effective minimally invasive procedure for the treatment of hepatocellular carcinoma at certain special regions, which is difficult to treat with other imaging guidance approaches. With its unique and superb imaging functions, MRI plays an important role in the display, guidance, and monitoring of the cryoablation procedure in treating hepatocellular carcinoma at these special regions. Equipped with an MRI-compatible optical navigation system, MRI-guided therapy makes the cryoablation procedure more precise and safe.
