Abstract
A method of imaging a corporeal situs by radiological techniques, comprising delivery to the corporeal situs of an imagingly effectively amount of a physiologically acceptable composition comprising a boron reagent. A variety of illustrative boron reagents is described, including iodinated boron salts, and boron-containing cyclophosphazene and polyphosphazene reagents having radiopaque character. The reagents and method of the present invention may be employed for a wide variety of radiological imaging applications, e.g., excretory urography, angiocardiography, and aortography.
