Angiography and scintigraphy of human pancreatic allografts.

Serial graft angiographies and scintigraphies were obtained in 4 human pancreatic allograft recipients. Important information was obtained both of graft morphology and function. Graft rejection was accompanied by characteristic abnormalities, including arterial irregularities and prolonged contrast medium passage time. On scintigraphy, rejection was associated with reduced isotope uptake.
