Proper design of the arterial spin-labeled (ASL) readout trajectory can minimize signal loss, reduce artifacts, and consequently improve the quality of ASL-derived perfusion maps. High performance gradients can improve MR image quality in spiral acquisition to reduce susceptibility and off-resonance effect. However, the eddy current and the system delay can degrade image quality by causing image rotation and blurring effects. In this work, the image artifact was corrected with a truer trajectory measured by a dynamic field camera. The effects of the trajectory correction on ASL images are investigated on a low-cryogen, compact 3T MRI system.
