18 prostate cancer patients underwent DCE-MRI scans on a
3T scanner) using a single channel RF transmit Q-body
and 32-channel phased-array surface coils, while 21
patients were imaged on the same scanner with a parallel
RF transmission upgrade. Comparison of baseline signal
and signal enhancement in the left and right femoral
arteries, indicates that baseline signals and signal
enhancement are significantly more symmetrical. High
field (3.0 T) MRI scanners equipped with
multiple-channel parallel RF transmission enhances the
symmetry of arterial input function in femoral arteries
resulting in more consistent and homogeneous
quantitative pharmacokinetic modeling in DCE-MRI of
prostate cancer.
