Medgadget reports that GE Healthcare has introduced a new MRI technique that improves imaging of soft tissue and bone in patients with metal joint implants. They say that MAVRIC SL helps to reduce artifacts caused by the presence of metal in both in-plane and through-plane dimensions in comparison to conventional MR techniques.
Apparently, MAVRIC SL allows for MRI to be used to monitor for adverse reactions in and around the implant area. MAVRIC SL consists of an acquisition technique and post-processing software. It is intended for use on GE 1.5 and 3.0T MRI systems and received FDA approval December 2012.
The results of a clinical study using the technique have been released in the Journal of Bone and Joint Surgery. The study concludes that potentially synovial volume on MRI could be used as a marker in the longitudinal assessment of asymptomatic patients with metal-on-metal hip resurfacing and in identifying patients with adverse local tissue reaction.
