Positron emission tomography–computed tomography (better known as PET-CT or PET/CT) is a nuclear medicine technique which combines, in a single gantry, a positron emission tomography (PET) scanner and an x-ray computed tomography (CT) scanner, to acquire sequential images from both devices in the same session, which are combined into a single superposed (co-registered) image.
Positron emission tomography (PET) [1] is a functional imaging technique that uses radioactive substances known as radiotracers to visualize and measure changes in metabolic processes, and in other physiological activities including blood flow, regional chemical composition, and absorption.
The game features over 1,000 pets to collect and allows players to trade pets from other people and hatch pets from loot boxes known as eggs.

Brain positron emission tomography is a form of positron emission tomography (PET) that is used to measure brain metabolism and the distribution of exogenous radiolabeled chemical agents throughout the brain. PET measures emissions from radioactively labeled metabolically active chemicals that have been injected into the bloodstream.

This is a list of positron emission tomography (PET) radiotracers. These are chemical compounds in which one or more atoms have been replaced by a short-lived, positron emitting radioisotope. Cardiology
PETSCII (PET Standard Code of Information Interchange), also known as CBM ASCII, is the character set used in Commodore Business Machines' 8-bit home computers. This character set was first used by the PET from 1977, and was subsequently used by the CBM-II , VIC-20 , Commodore 64 , Commodore 16 , Commodore 116 , Plus/4 , and Commodore 128 .
The code is also known as the "Contra Code" and "30 Lives Code", since the code provided the player 30 extra lives in Contra. The code has been used to help novice players progress through the game. [10] [12] The Konami Code was created by Kazuhisa Hashimoto, who was developing the home port of the 1985 arcade game Gradius for the NES.
