The coil wasn't the only challenge, though. The scientists also had to create a triggering device designed to synchronize cardiac imaging with heart motion -- and one that was compatible with 7T MRI's strong magnetic fields. Previously, "the challenge of synchronization of data acquisition with the cardiac cycle" has been a major impediment for cardiovascular MRI, the scientists involved with the device wrote last fall in Journal of Cardiovascular Magnetic Resonance.
But, Prof. Thoralf Niendorf, the investigator of the study, said his team was able to correlate image exposure with the heartbeat.

It is, of course, an early step, and the scientists said there were many, many more to go before 7T MRI is ever used routinely on patients.
