Several
different accelerated imaging methods exist that can improve the acquisition
of dynamic data. Clinical adoption of
many of these methods has been slow, partially due to the difficulty in
conclusively proving the extent to which a specific method provides
additional diagnostic information that would not otherwise have been
available. We have created a realistic
digital phantom from which k-space data for a DCE exam can be simulated and reconstructed
by both Cartesian and non Cartesian acceleration methods. We use the phantom to quantitatively
analyze and compare the performance of multiple accelerated imaging methods.
