An abdominal dynamic contrast enhanced (DCE) examination
typically consists of a series of images acquired with
the same imaging sequence. The resulting images
represent the same anatomy, but differ due to contrast
agent arrival and wash-out. The contrast agent injection
can make it more difficult for the patient to hold their
breath properly, resulting in severe artifacts after
contrast injection. Data are acquired with a modified
adaptive sampling pattern, which implies higher
undersampling for shorter breath-holds. The
post-contrast images should, therefore, benefit from a
joint reconstruction of pre- and post-contrast images,
which is evaluated in this work.
