Actual (reported)Correlation of body weight with the variation coefficient (image noise).
The image noise will be measured by VOI (Volume Of Interest) in the images. The units of measure will be kilograms (kg) for body weight, and percentage for the variation coefficient.

A total of 85 18F-FDG-PET adult studies were gathered over a 3-month period and retrospectively evaluated.
To verify the application of methodology in clinical routine, we conducted a second phase of the study prospectively in 250 subjects (phase 2) using inclusion and exclusion criteria of the retrospective study (phase 1).
Will be observed all patients who perform PET / CT examinations, independent of clinical indication, in nuclear medicine at Hospital Sao Rafael. Those who show interest in participating in the study, will be provided free and informed consent form (ICF) for your appreciation. This evaluation will serve for analysis and quantification of PET-CT images.
