[Gammagraphy of the carotid glomus]

Using the colorant proteic complex labell with Tc-99 m. we visualize--by the first time--the carotideal glomus in the human in 6 volunteers and one patient with tumor. The results are very encorageous: the method was simple and safe (one single dose endovenously) and hardless (no radiotoxicity presents in 3 months of clinical and laboratory controls) and there is a good visualization by scan of carotideal bodies "in vivo", in human being. We think this new method and labell compound could be useful in research and medical diagnoses.
