Low resolution: A ct has advantages and disadvantages: a ct is cheap, fast done and gives a great information about blood, bone and calfifications. However, it is done with x- ray, and has low resolution of tissue such as the brain. An MRI might be at time better, depending on the goal of the exam.

Radiation: Pt scan uses radioactive glucose that is injected. The glucose is taken up by organs for energy, and we measure how active the tissue is. Dead tissue, like a stroke takes up no glucose. Cancer takes up too much. Ct only takes a picture.
