Current free-breathing, respiratory-triggered, heavily T2-weighted 3D fast/turbo spin-echo acquisitions work well in many patients for MRCP, but non-diagnostic results are obtained in some patients, particularly those with irregular breathing patterns during the several-minute acquisition. Thus, there has been renewed interest in 3D MRCP techniques that can be completed within a single breath-hold period as an alternative for patients in whom free-breathing techniques are inadequate. This work demonstrates that breath-hold 3D MRCP based on a 3D stack-of-spirals turbo spin-echo acquisition, which uses in-plane acceleration to achieve a reasonable breath-hold time, can provide good image quality for evaluation of major ductal structures.
