Combined positron emission and computer tomography in diagnostics of primary metastases in the lymph nodes of the neck
The efficiency of combined positron emission and computer tomography in the diagnostics of primary metastatic lymph nodes of the neck was analyzed. We determined that f this method provided additional information about progression and localization of primary tumors in 80% of patients. At the same time, primary tumor was identified in 27% of the completely examined patients and metastatic lesions in other organs and lymph nodes were detected in 47% of these patients.
