How does the integration of PET/CT impact radiation dosage?

• A. It always increases radiation exposure
• B. It helps to minimize redundant imaging
• C. It has no effect on radiation dosage
• D. It requires more imaging sessions

Answer: (B)

The integration of PET/CT significantly impacts radiation dosage by helping to minimize redundant imaging. When these two imaging modalities are combined, they provide complementary information—metabolic activity from PET and anatomical detail from CT—within a single session. This means that patients can receive both types of imaging at once, rather than having to undergo separate procedures for each. By consolidating the imaging into one session, the overall radiation exposure to the patient is often reduced compared to having multiple imaging sessions. This efficiency not only enhances patient comfort and decreases operational costs but also reduces the cumulative radiation dose that a patient might face if multiple scans were performed separately. Therefore, the integration of PET and CT ultimately leads to a more judicious use of imaging resources and better management of radiation exposure.
