Yon eskanografi PET (tomografi avèk emisyon pozitwon) se yon kalite lamedsin nikleyè ki kreye yon imaj aktivite metabolik kò ou epi ki montre ritm selil kò ou dekonpoze ak itilize sik (glikoz). Nou fè sa lè nou enjekte yon ti kantite materyèl radyo-aktif (radyo-trasè) nan kouran sangen ou epi nou rete tann li pou epapiye nan zòn sib la. Emisyon radyo-aktif ki sòti nan radyo-trasè a detekte avèk yon kamera espesyal oswa yon aparèy imajri ki pwodui imaj ak enfòmasyon molekilè detaye.

A PET (positron emission tomography) scan is a type of nuclear medicine that creates an image of your body's metabolic activity and shows the rate at which your body's cells break down and use sugar (glucose). This is done by injecting a small amount of radioactive material (radiotracer) into your blood stream and waiting for it to disperse to the area of focus. Radioactive emissions from the radiotracer are detected by a special camera or imaging device that produces pictures and detailed molecular information.
