Cerebral Scintigraphy with 111Indium Oxine-Labelled Leukocytes in the Differential Diagnosis of Intracerebral Cystic Lesions

CT scanning and scintigraphy with 111Indium-oxide-labelled whit blood cells were used to study 32 cases of intracerebral cystic lesions The results and the criteria of positivity used to lower the fais positive rate are discussed. A new criterion, designed to assess th time course of the scintiscan and so reduce still further the frequenc of false positives is put forward.
