Diclofenac is a nonsteroidal
anti-inflammatory drug that is frequently prescribed to reduce inflammation and
pain. It reduces the prostaglandin-synthesis and may consequently have an
effect on renal perfusion. We investigated whether arterial spin labeling can detect
reduction of renal perfusion after oral and topical application of diclofenac
compared to baseline measurements. Ten healthy subjects underwent functional MRI
of the kidney. After oral application of diclofenac renal perfusion was reduced
compared to baseline measurements (321±13
vs. 345±16 ml/(min*100g), p<0.01). No significant changes were found after
topical application. In conclusion, ASL can detect discreet changes of renal
perfusion that occur after application of diclofenac.
