Question

How does a PET scan differ from a CT scan?

		A PET scan uses magnetic technology, while a CT scan relies on radioactive elements.
		A PET scan detects abnormal brain activity, while a CT scan monitors normal brain activity.
		A PET scan measures changes in activity, while a CT scan provides a snapshot.
		A PET scan generates images of brain structures, while a CT scan tracks neural activity.

Answer 1

The correct answer is: -A PET scan measures changes in activity, while a CT scan provides a snapshot.

The PET scan uses a radioactive element to present a 3D image of the organs inside the body and shows the major changes in their activity. While CT scan use X-Ray to provide a high-quality image of the internal organs.
