Abstract

Purpose: Image quality in clinical dynamic contrast enhanced (DCE) MRIof the abdomen is often challenged by respiratory motion artifacts. DCEstudies are commonly acquired at the end of the MRI examination, after the patient has gone through several breath-holds and the average breath-holdcapability is known. However, patients may have trouble holding their breath after contrast injection and this is often unpredictable as many of themmay have been able to do so earlier in the exam. To overcome this problem, DCE imaging with flexible scan termination1is proposed in this work, toautomatically adapt to the breath-hold capabilities of the patient.Shorter breath-holds are compromised with lower but adaptedspatial resolution.
