The effect of contrast media on patient motion during cerebral angiography

Conray, Renografin-60, and Reno-M-60 were compared in 40 patients undergoing cerebral angiography. Pain during injection, as evidenced by head motion, was documented using subtraction. Conray produced less had head motion and therefore a superior subtraction study than either Renografin-60 or Reno-M-60 and was also subjectively the least painful of the three.
