A method for dual-contrast imaging of the abdomen within one breath-hold is proposed, that is able to cope with potential premature breathing-onset. Because of ultra-fast sequence switching the scans are performed quasi-simultaneously and without spatial misregistration. The first scan is sampled conventional one, while the second is adapted to the breath-hold capabilities of the patient. An adaptive sampling pattern was chosen that enables flexible scan termination. Shorter breath-hold duration comes as a compromise at the cost of lower resolution.
