201Thallium scintigraphy--a new method for radionuclide imaging of the uterus

A new radionuclide method for uterus imaging is described. After intravenous application of 201Tl chloride the myometrium can be displayed by means of a gamma camera and a small digital computer. Early results suggest that Tl accumulation by the uterus depends on its histopathologic structure. After intra-uterine injection of 133Xe in saline demarcation between myometrium and uterine cavity is possible.
