Nasopharyngeal Carcinomas: What Radionuclide Imaging Can Do?
Authors: Ambreen Khawar
Abstract: The advent of both improved imaging systems and new radioactive agents has increased the effectiveness of nuclear medicine in diagnosing and treating various tumors. Assessment of treatment response and recurrence in the pharyngeal tumors specially the Nasopharyngeal carcinomas (NPC) has been given a considerable attention in the past decade. In this chapter, a review has been made keeping in focus, the utilization of nuclear medicine radiopharmaceutical agents like Thallium-201, Tc-99m MIBI, Tc-99m Tetrofosmin and F-18 FDG PET in the detection and evaluation of disease regression/ progression and recurrence of malignant nasopharyngeal disease. It is concluded that radionuclide imaging offers added value when compared with conventional morphological imaging techniques for the purpose of detection and evaluation of residual and recurrent Nasopharyngeal Carcinomas.
