Abstract
Ushbu maqolada pozitron-emission tomografiya (PET) usulining fizik asoslari, ishlash prinsipi hamda tibbiyotdagi diagnostik ahamiyati yoritilgan. PET radioaktiv izotoplar yordamida organizmdagi metabolik jarayonlarni aniqlash imkonini beruvchi zamonaviy tasvirlash usuli hisoblanadi. Tadqiqotda pozitronlarning annihilatsiya jarayoni, gamma-nurlanishlarning qayd etilishi va tasvir hosil bo‘lish mexanizmlari ko‘rib chiqilgan.
Shuningdek, PET ning onkologiya, kardiologiya va neyrologiya sohalarida qo‘llanilishi tahlil qilingan. Ushbu usul kasalliklarni erta aniqlashda yuqori aniqlikka ega bo‘lib, zamonaviy tibbiy diagnostikaning muhim qismi hisoblanadi.
