Here we present initial in vivo lung density
measurements at three different lung volumes using a
portable low field NMR system built in our lab. The
measurements are proportional to lung density. As one
predicts, the signal decreases with increasing lung
volume. The measurements were highly reproducible with
std < 12%. The SNR in a single 40s breath-hold at TLC
was measured to be over 110. We also report initial
hyperpolarized Xe measurements in a phantom using the
same system with high SNR observed in a single data
acquisition.
