positron emission tomography scanner
A doctor uses a positron emission tomography scanner to examine a patient's brain.
Noun: A positron emission tomography scanner is a medical imaging device that uses a radioactive tracer to produce detailed, three-dimensional images of metabolic processes within the body. It is a type of tomograph that creates cross-sectional views to show how tissues and organs are functioning.
The term is used specifically in medical and scientific contexts to refer to the machine that performs PET scans. * The hospital acquired a new positron emission tomography scanner to improve its cancer diagnostics. * Researchers used the positron emission tomography scanner to study brain activity.
- The device is often referred to by its acronym, PET scanner.
- The patient was wheeled into the room containing the PET scanner.
- PET scanner (n): The common abbreviated form of "positron emission tomography scanner".
- Tomograph (n): A general term for any device that produces images of sections through an object.
- Positron emission tomography (PET) (n): The name of the imaging technique itself, not the machine.
- PET scanner
- PET imager
- To undergo a PET scan: To have the imaging procedure performed.
- The doctor recommended that the patient undergo a PET scan.
- PET scan results: The images and data produced by the scanner.
- The PET scan results revealed areas of high metabolic activity.
