To overcome the limited volumetric coverage of standard Time-of-Flight (TOF) techniques, the aim of this study was to investigate the combination of TOF and Continuously Moving Table (CMT) acquisitions for peripheral vein imaging based on image subtraction. Two acquisition strategies are presented: A 2-step method with two-fold CMT acquisition and an advanced 1-step method with an interleaved arrangement of imaging and saturation slices requiring only one continuous scan. Image quality was evaluated by semi-quantitative image grading and by SNR and CNR analysis for peripheral veins in healthy volunteers. Results were compared to a standard stationary 2D TOF multistation acquisition.
