Multitransmit for body MRI: Is it worth it?


October 18, 2013 -- At higher field strengths, the hope is for new technology to lead to more clinical applications benefiting from homogeneous MR images, but can it ever be cost-effective? That was the main question addressed during a round table discussion at the recent meeting of the European Society of MR in Medicine and Biology (ESMRMB) in Toulouse, France.

At the session, experts outlined the promise of parallel transmit (pTX) whole-body MRI and how it is already improving abdominal and prostate cancer detection and changing individual patient outcomes. The next couple of years will be a learning curve in understanding how independent pTX channels can improve image quality and change patient or even MR management, and future clinical systems could include eight, 16, or even 32 channels at field strengths of up to 7 tesla, they believe.
"We are only at the beginning of the journey," said Dr. Stefan Haneder, the section chief of vascular and abdominal imaging at the Institute of Clinical Radiology and Nuclear Medicine at University Medical Center Mannheim in Germany and a panel speaker during a discussion focusing primarily on the cost benefits of pTX whole-body MRI.
