Image quality in clinical dynamic contrast enhanced (DCE)
MRI of the abdomen is often degraded by respiratory
motion artifacts, making diagnosis difficult.
Breath-holding is an efficient strategy to minimize
respiration induced artifacts in the abdomen if the
patients capability is sufficient. In many cases,
patients have trouble holding their breath after
contrast injection, even if they were able to do so
earlier in the exam. To overcome this problem, DCE
imaging with flexible scan termination is proposed in
this work, to automatically adapt to the breath-hold
capabilities of the patient. Shorter breath-holds are
compromised with lower but adapted spatial resolution.
