title: [Gamma-topographic study of patients with pathological orbital processes].
abstract: A gamma-topographic study of the orbit was performed in 64 patients with unilateral exophthalmus using 99m Tc-pertechnetate. Some peculiarities in the RP distribution in the focus of lesion in malignant and benign neoplasms and inflammatory processes in the orbit were revealed. Correlation between RP accumulation intensity in the focus and the degree of RP vascularization and volume was shown. The method does not allow assessment of the morphological nature of a process however its use extends the diagnostic potentialities in specifying the genesis of unilateral exophthalmus and facilitates the choice of appropriate therapy.
