Synchronous acquisition of 1H and HP gases in the lungs
provide complementary structure function information
from the lung with inherent spatial temporal
registration. To date 1H images have been acquired using
the systems body coil, which has low SNR compared to
dedicate receive coils. This study demonstrates the
design and application of a dedicated 1H receiver array
to improve the proton lung SNR in synchronous
acquisition with HP gas 3He and 129Xe at 1.5T.
Synchronous acquisition with two birdcage transmitter
receiver arrays has also been demonstrated. Both
represent novel developments in the field of multi
nuclear MRI RF engineering
