The usefulness of breath-hold 3D MRCP at 3T MRI has recently been reported. Moreover, the denoising approach with deep learning-based reconstruction (dDLR) is a novel technique. We assessed the image quality of conventional respiratory-triggered 3D MRCP (Resp) and breath-hold 3D MRCP using Fast 3D mode without and with dDLR (BH, dDLR-BH) at 1.5T, by comparing the overall image quality and duct visibility scores. Breath-hold 3D MRCP compared favorably with respiratory-triggered MRCP at 1.5T. dDLR can improve the overall image quality and duct visibility of breath-hold 3D MRCP, and the visibility of the right and left hepatic ducts was improved statistically.
