In simultaneous whole-body PET/MR imaging, data is usually acquired in a multi-station (step-and-shoot) approach. In contrast, an acquisition paradigm with continuous table motion that was introduced recently allows for seamless whole-body coverage and greater flexibility in the planning workflow. To allow the use of continuous table motion acquisitions in clinical protocols, it must be evaluated which impact table motion speed has on MR and PET image quality. This was performed for the available MR protocols that support continuous table motion (FLASH 2D, FLASH 3D, TSE, HASTE, BLADE) and for PET imaging for several different table speeds.
