Interpretation:
The detection of radiotracer needs to be explained.
Concept introduction:
A radiotracer is a radioisotope which emits radiations which are non-ionizing. It is used to detect the presence of an element.
Answer to Problem 75A
Radiotracer can be detected by placing body scanner and recording the
Explanation of Solution
Positron emission trans axial tomography (PET) is radiation-based medical diagnostic tool. In this procedure, a radiotracer which is decayed by positron emission is injected into the patient’s blood. Positrons emitted by the radiotracer cause gamma-ray emissions that are then detected by sensors surrounding the patient.
PET scans (positron emission tomography) are used for medical purposes like physiological activities like
