ABSTRACT:
An X-ray contrast method containing as the essential radioopaque ingredient finely divided tantalum metal dispersed in a liquid vehicle having critical viscosity and flow properties. The metal has an average particle diameter in the range from about 0.5 to about 30 microns, and preferably in the range from about 1 to about 5 microns in a physiologically and pharmaceutically acceptable amount for use in obtaining X-ray films of sufficient clarity and detail for use in bronchography.
