Isotope renography and transplant angiography were performed during 37 acute episodes of renal transplant rejection. Renography demonstrated rejection in 70% of the irreversible and 55% of the reversible processes. Angiography, though reliable in irrerversible rejection, was diagnostic in only 30% of the reversible cases. Renography is the method of choice for diagnosing rejection and its accuracy is improved by repitition. Angiography should be reserved for patients whose renal function is not restored by treatment for rejection.
