title: [Computerized tomography in planning radiation therapy of patients with nasopharyngeal squamous-cell cancer].
abstract: In 27 patients with squamous cell nasopharyngeal cancer, the results of a routine x-ray study were correlated with those of computerized tomography. It has been shown that the resolution of computerized tomography is about twice as high in specified diagnosis of a disseminated tumor process, particularly in cases when the tumor involves the orbit, retrobulbar space, pterygopalatine fossa, uncinate processes, nasal cavity, etc. Besides, computerized tomography can de effectively used to correct irradiation conditions during radiation therapy and to evaluate therapeutic results.
