Abstract
The pharynx is a part of the digestive tube, which is placed behind the nasal cavities, mouth, and larynx. It is a musculomembranous tube, somewhat conical in form, broad upward, and narrow downward. Its extent is from the inferior surface of the skull upto the cricoid cartilage (sixth cervical vertebra). Pharynx is about 12.5 cm in length and is subdivided into three parts: (a) Nasopharynx, (b) oropharynx, and (c) laryngopharynx from upward down.

Standardized uptake value, SUV, (also referred to as the dose uptake ratio, DUR) is a widely used, simple PET quantifier, calculated as a ratio of tissue radioactivity concentration (e.g., in units kBq/ml) at time T, CPET (T) and injected dose (e.g., in units MBq) at the time of injection divided by body weight (e.g., in units kg).
SUVbw = CPET (T)/(Injected dose/Patient’s weight)
