Zusammenfassung
Purpose: The feasibility of highly resolved arterial spin labeling (ASL) perfusion imaging of the kidneys was tested and proven at 3 Tesla using a flow-sensitive alternating inversion recovery (FAIR) true fast imaging in steady precession (TrueFISP) technique. Methods: Kidney perfusion maps of six healthy volunteers and two patients were acquired using a clinical 3 Tesla whole-body scanner. An ASL sequence with FAIR spin-preparation and a TrueFISP signal recording strategy was adapted for high-resolution perfusion imaging of the kidneys at 3 Tesla. To avoid banding artifacts in TrueFISP images, which are promine…
