[Nuclear medicine demonstration of intraocular tumors using gamma-radiating radionuclides. 1st clinical results]. / Nuklearmedizinische Darstellung intraokularer Tumoren mittels gammastrahlender Radionuklide. Erste klinische Ergebnisse.

A non-invasive method of detecting intraocular mass lesions is described which uses 67gallium citrate and 99m-technetium pertechnetate. It was used in 33 cases. In 73.7% of the patients with malignant melanoma of the eye there was a significant increase in the storage of the tracer. There was no difference in the results obtained with 67gallium citrate and 99m-technetium pertechnetate. Small, flat and peripheral tumors may not be detected. In some cases old intraocular hemorrhages may also lead to false-positive results. In contrast to the 32P-test the method described can be used in cases with opaque media. The radiation dose is about one-tenth of that given with the 32P-test.
