This isn't really a question, but here we go...
PET technology is used in PET scans in hospitals. It is the largest scale use of antimatter currently available, as the emitted positrons are in fact the anti-particles of electrons. Therefore used improperly it can be extremely dangerous as if a particle meets its antiparticle they will annihilate.
Positron emission tomography (PET) is a nuclear medicine imaging technique which produces a three-dimensional image or picture of functional processes in the body. The system detects pairs of gamma rays emitted indirectly by a positron-emitting radionuclide (tracer), which is introduced into the body on a biologically active molecule. Images of tracer concentration in 3-dimensional or 4-dimensional space (the 4th dimension being time) within the body are then reconstructed by computer analysis. In modern scanners, this reconstruction is often accomplished with the aid of a CT X-ray scan performed on the patient during the same session, in the same machine.
radioactive glucose, a sugar, is injected into the body. The glucose travels to metabolically active sites, including cancerous regions that require large amounts of glucose. The PET scan detects the radioactivity
Positron emission tomography (PET) is a scanning technique used in conjunction with small amounts of radiolabeled compounds to visualize brain anatomy and function.
A tracer courses through the bloodstream to the target organ, where it emits positrons. The positively charged positrons collide with negatively charged electrons, producing gamma rays.

If you are talking about beta+ decay, then the emission of a positron is accompanied with the emission of an electron neutrino.
Technically yes; but the amounts of anti-electrons (also called "positrons") is truly tiny. PET is an acronym for Positron Emission Tomography.

Work backwards. Positron emission means (essentially) a proton decayed into a neutron/positron pair. The mass number remains the same, but the atomic number goes down one to Bromine. Krypton has an isotope that fits this bill.

Arsenic 74 can be used as a positron emitter in PET - Positron Emission Tomography, the scope is to identify tumors.
Positron emission tomography
Functional magnetic resonance imaging (fMRI), positron emission tomography (PET), electroencephalography (EEG), magnetoencephalography (MEG), and single photon emission computed tomography (SPECT) are used to investigate brain activity.
The technique is called positron emission tomography (PET). It involves injecting a radioactive form of glucose into the bloodstream, which is then taken up by active brain regions. The scanner detects the emitted positrons to create a map of brain activity.
