Electroroentgenoscanning in clinical oncology

A combined method of electroroentgenoscanning was used for the recognition of tumors of different organs. Altogether 645 cancer patients were investigated. Special methods of investigation and tumorotropic radiopharmaceuticals 75Se-methionine, 67Ga-citrate, 85Sr, 113In, 99Tc, etc. were used. ERS was shown to be the most effective method for the detection of cancer of the lung, mediastinum (90%), head and neck (89%), and prostate (89 %). The method is particularly valuable for tumors developing in anatomical regions inaccessible for examination biopsy, and X-ray findings are not sufficiently clear. The use of ERS excludes possible errors in diagnosing disease on the edges of an organ, especially in liver and kidney investigation. The method also proved to be valuable for the assessment of therapeutic efficacy and correction of fields of irradiation
