Brief Summary

uEXPLORER total-body PET/CT in Nasopharyngeal Carcinoma

Detailed Description

A 194-cm-long total-body positron emission tomography/computed tomography (PET/CT) scanner (uEXPLORER), has been constructed to offer a transformative platform for human radiotracer imaging in clinical research and healthcare. The objective of this study is to determine its specific effect in newly diagnosed nasopharyngeal carcinoma compared with conventional PET/CT and the quantitative kinetic parameters including glucose metabolic rate (Ki), glucose transport rate of flow-in (k1) and flow-out (k2) between tissue and blood, and glucosamine-6-phosphatization rate in tissue (k3). All the neck lymph nodes suspected for metastatic in PET/CT were biopsied under the guidance of ultrasound for a pathological diagnosis.
