We present a novel method for measuring left-ventricular
end-diastolic volume (EDV) from highly under-sampled
k
-space,
without need for explicit image reconstruction. Using
retrospectively under-sampled
k
-space
data (8%), from 31 healthy volunteers, we show that the
method can accurately (r=0.91,
p
<
0.001) estimate EDV with a mean bias of just 11 ml. The
ability to parameterize features in the way we describe
allows for much faster, tailored quantitative imaging.
