Do we need suspended breathing with real-time axial continuously moving table MR imaging?

For three different 2D axial SSFP moving table sequences, we compared quality and potential distortion in the z-direction of breathhold versus non breathhold acquisitions reformatted into sagittal and coronal planes in 5 healthy volunteers. Distances between anatomic structures were comparable. No qualitative distortion is seen without breathhold; only motion artifacts generated by the heart are present, which do not influence the depiction of other structures including the hilar vessels. Further studies have to show if this technique can replace conventional imaging in patients who can not hold their breath; and whether this technique allows reliable, fast whole-body examinations.
