In the investigation of the arteriae coronariae by means of angiography, a comparative study has been done of two contrast media in the same patients, by injecting these media in a randomized order. The contrast media are sodium methylglucamine diatrizoate (10:66) and metrizamide, both used in a concentration of 370 mg I/ml. The reaction of the heart was registered in different ways with which also the influence on the blood pressure was measured. The quality of the films was judged by persons who were not acquainted with the sequence of the injections.
