EXTERNAL LOCALIZATION OF BRAIN-TUMORS EMPLOYING POSITRON-EMITTING ISOTOPES. Progress Report for July 1, 1959-July 1, 1960
Applications of positron-emitting isotopes and automatic scanning for the detection and localization of intracranial lesions are described. Problems of isotope production are reviewed. Emphasis is placed on the production of As/ sup 72/ with a half life of 26 hr. Results are reviewed on 385 scans performed over a 3.5-year period on a special group of 534 patients. Nearly all proved to have focal lesions established by gross anatomical and histological diagnosis after surgery and autopsy. In this group a correct diagnosis was made in 80% of 249 tumors scanned with As/sup 74/ and 70% of 84 tumors scanned with Cu/sup 64/. During 1959, 616 patients were scanned with As/sup 74/ and Cu/sup 64/. A study was made on applications of Ga/sup 68/ in scanning. Design modifications are reported in a positron camera. Preliminary applications are illustrated. (C.H.)
