The renal perfusion map from one of the patients (CKD stage 2, male, 58 years of age). Reduced global perfusion in the cortex was observed compared to a healthy volunteer (subject 6 in Table 2).

The navigator-gated sequence allowed sufficient signal averaging to provide a reasonable perfusion map in the patient.
