A study to investigate the presence and repeatability of
IVIM in breast parenchyma of healthy volunteers. Two
optimised IVIM protocols were applied in 11 healthy
volunteers, and the data was fitted mono- and
bi-exponentially with a cut-off for D of 200s/mm2. RMSEs
indicated that the biexponential fit was better. The
repeatability of D for b-values10 and b-values20 was 9%
and 20% respectively, with the repeatability of f and D*
showing more variation at up to 0.12 and 0.039s/mm2.
The results indicated that there was an IVIM effect in
breast parenchyma.
