Abstract
Roentgenograms, taken at the moment of opacification of the structures to be visualized following rapid intraven. inj. of 70% soln. of diodrast into a large vein of the arm, permitted the authors to visualize for the first time during life the nature and extent of pathological heart disease. Exact measurements were made possible by this procedure.
