A new process of organ scanning utilizing a rapid, self developing color camera has facilitated diagnosis by this technique, Henry L. Jaffe, MD, of Los Angeles, told The Journal. Jaffe presented this refined scanning technique at the annual meeting of the Thyrotoxicosis Therapy Follow-Up Study directors held at the Mayo Clinic during the meeting of the American Thyroid Association.
"This is a new clinical method of isotope diagnostic study that utilizes the Polaroid color film process. We can determine quantitatively the intensity of uptake of the tracers by the various colors which are actually indicators of the rate meter activity of the conventional scanner," Jaffe said. He emphasized that familiarity with the characteristics of tracer uptake of the particular organ being scanned is essential. In the liver, for example, a high uptake of the tracer is indicated by a red colored area and shows normal function. However, in other organs,
