Question 1

What is the Meaning of PET Scan?

Accepted Answer

Positron Emission Tomography, or PET Scan, is a sophisticated nuclear medicine imaging technique. This diagnostic procedure provides clinicians a view into metabolic activity of tissues and organs. It fundamentally differs from anatomical imaging, prioritizing physiological function over structural details.

Question 2

What is the Context of PET Scan?

Accepted Answer

A PET scan operates within the physiological landscape, invaluable across oncology, neurology, and cardiology. Its utility extends to hormonal health, aiding identification of metabolically active endocrine tumors or assessing metabolic impact. This imaging modality reveals functional changes at a cellular level, often preceding observable structural changes.

Question 3

What is the Significance of PET Scan?

Accepted Answer

This imaging tool holds substantial importance in clinical practice, guiding crucial diagnostic and treatment decisions. It assists in early disease detection, accurate malignancy staging, and precise monitoring of therapeutic responses. By providing insights into tissue viability and metabolic rates, a PET scan directly influences patient management and improves health outcomes.

Question 4

What is the Mechanism of PET Scan?

Accepted Answer

The procedure involves intravenous administration of a small, safe dose of a radioactive tracer, typically fluorodeoxyglucose (FDG), a glucose analog. Cells with elevated metabolic rates, characteristic of many disease processes, preferentially absorb this tracer. As the tracer decays, it emits positrons that interact with electrons, producing gamma rays. These are detected by the PET scanner, and collected data is reconstructed into detailed 3D images.

Question 5

What is the Application of PET Scan?

Accepted Answer

Clinically, a PET scan distinguishes between benign and malignant lesions, determines cancer spread, and evaluates chemotherapy or radiation therapy efficacy. It also assesses brain activity in neurodegenerative conditions and myocardial viability after a heart event. Patients typically undergo fasting before the scan to optimize tracer distribution and uptake.

Question 6

What is the Metric of PET Scan?

Accepted Answer

Metabolic activity is measured by analyzing tracer uptake intensity in specific regions of interest on PET images. This uptake is often quantified using the Standardized Uptake Value (SUV), providing a numerical representation. Clinical interpretation involves comparing SUV values, considering anatomical correlations from co-registered CT scans, and integrating findings with the patient's clinical history.

Question 7

What is the Risk of PET Scan?

Accepted Answer

The primary risk with a PET scan is exposure to a small, controlled dose of ionizing radiation. While generally low, this necessitates careful clinical consideration. Allergic reactions to the administered radiotracer are exceedingly rare. Pregnancy is a contraindication due to potential fetal radiation exposure; precautions are taken for diabetic patients to ensure optimal tracer uptake and accurate results.
