There are several situations, such as some interventional applications or intracavitary placement, where it would be desirable to remotely tune and match a local RF coil. Although remote lumped element placement will result in decreased SNR, it is likely that net loss in SNR may be a function of the designs used. This study investigated the SNR trade-off of different methods of remote tuning by comparing the SNR that could be achieved with the placement of lumped elements at the coil. A large variation in SNR based on method was observed.
