What is a common application of PET scans in oncology?

• A. Monitoring blood pressure
• B. Assessing tumor size and metabolic activity
• C. Evaluating heart rate variability
• D. Measuring blood sugar levels

Answer: (B)

The application of PET scans in oncology primarily revolves around assessing tumor size and metabolic activity. PET scans are particularly adept at identifying cancerous tissues because they utilize radiotracers that highlight areas of increased glucose metabolism, which is characteristic of many tumors. Cancer cells often have higher metabolic rates compared to normal cells, making them more active in consuming glucose. This metabolic activity can be visualized through a PET scan, allowing for the evaluation of how aggressive a tumor may be and its responsiveness to treatment over time. This capability makes PET scans invaluable in diagnosing cancer, monitoring the effectiveness of therapy, and detecting recurrences after treatment. By determining both the functional and metabolic characteristics of tumors, PET scans contribute significantly to personalized oncology treatment planning and management, enhancing outcomes for patients.
