Incidence of contrast nephropathy from cerebral CT angiography and CT perfusion imaging.
The incidence of contrast-induced nephropathy was examined in 1,075 patients receiving routine CT angiography and CT perfusion brain imaging at a single institution. Fifty-two patients had a creatinine rise of > or =0.5 mg/dL. In four patients (0.37%), the administration of IV contrast medium possibly contributed to renal failure. Two patients (0.19%) received temporary hemodialysis during hospitalization. The incidence of contrast nephropathy in neurovascular patients is low.
