Should functional renal scans be obtained prior to upper abdominal IMRT for pancreatic cancer?

Conclusions In our series, approximately 11% of patients with pancreatic cancer have asymmetrical kidney function not identified by kidney size, serum BUN, Cr, GFR, or a significant past medical history. These data suggest that in cases where renal radiation doses exceed a V18 of 20–30%, or there is concern about baseline renal function, a functional renal scan should be considered.
