eighteen-FDG PET-CT is Among the most correct methods for diagnosing the key HNC lesion. The lesion cannot be assessed by way of visual inspection with or with no concurrent vision-guided biopsy. The sensitivity and specificity of PET-CT for figuring out inspection-occult oropharyngeal SCC are already measured as staying above ninety%.
Areas of bigger depth are termed “incredibly hot spots.” These may perhaps demonstrate big concentrations of your radiotracer and the place There exists a high volume of chemical or metabolic action. Much less powerful places, or “chilly spots,” point out a smaller sized focus of radiotracer and less action.

The photons strike scintillator crystals housed in a tool that encircles the affected individual. Crystals used in modern day imaging devices change by manufacturer, Each and every with its individual photon detection generate and backbone; a standard crystal type used for PET is lutetium oxyorthosilicate. The crystals transmit the photoelectric Vitality into circuits that change the electrical Electricity into computer information.
