The scintillation (photon) detector is created to detect only photons that concurrently sign up when touring in opposing 180-diploma Instructions (this means they may have originated through the identical site). So, a computer algorithm may be used to straight pinpoint the source of The 2 photons inside numerous millimeters of error in three dimensions. The resolution of scanning employing eighteen-FDG PET is usually thought of as eight mm, meaning that a hypermetabolic tissue that's more compact than 8 mm might not be noticeable.
Based upon which spot is below examination, supplemental assessments involving other tracers or medication may be applied. This might lengthen the process time to 3 hrs.
