Positrons
Subatomic particles with the same mass as electrons but a positive charge, involved in certain types of radioactive decay.
Diagnostic Procedure
A method of examination to identify the presence of a disease or condition in the body.
Radiation
The emission of energy as electromagnetic waves or as moving subatomic particles, especially high-energy particles that cause ionization.

Final Answer :
D
Explanation :
The diagnostic procedure that involves the development of biologic images based on the detection of radiation from the emission of positrons is called PET (positron emission tomography). PET uses a radioactive substance (tracer) that is injected into the body, which emits positively charged particles (positrons). These particles collide with electrons in the body, resulting in the release of photons (gamma rays), which are detected by a scanner and used to create images of the body's internal structures and metabolic activity. CT (computed tomography) and MRI (magnetic resonance imaging) are also imaging techniques used in medicine, but they do not involve the detection of radiation from the emission of positrons. BE is not a recognized imaging technique in medicine.
