A relaxation corrected fat fraction (ff) was measured in
the human pancreas in one breath-hold, avoiding
breathing motion artifacts. Volume and position of the
pancreas make the measurement within one breath-hold
challenging, but using short repetition rates a series
of TE could be recorded with signal averaging in one
breath hold. Estimates of water and fat T1s were
incorporated by recording fully relaxed scans and used
for saturation correction of the signals. Twenty
subjects were examined yielding T2 and T1 corrected ff
measurements the human pancreas and estimated of the T1
and T2 of pancreatic water and fat signals.
