What is the primary purpose of using computed tomography (CT) in combination with PET?

• A. To decrease patient convenience
• B. To reduce the costs of imaging
• C. To provide detailed anatomical information
• D. To enhance the speed of the PET scan

Answer: (C)

The primary purpose of combining computed tomography (CT) with positron emission tomography (PET) is to provide detailed anatomical information. When these two imaging modalities are fused, the functional data from PET, which shows metabolic activity, is paired with the high-resolution anatomical images from CT. This fusion enhances the overall quality of the imaging study by giving clinicians a clearer and more precise view of where in the body the metabolic activity is taking place, allowing for better diagnosis, treatment planning, and monitoring of diseases, particularly cancers. The CT component helps to accurately locate the areas of interest identified on the PET scan, making it easier to interpret results and guide interventions.
