Answer to Question 1

ANS: B
Positron emission tomography (PET) is a form of nuclear imaging that combines elements of CT scanning and nuclear scanning to create a picture that represents the brain or other organs. The radioisotopes used emit positrons that cause pairs of gamma rays to be discharged and converted into images.

Answer to Question 2

ANS: C
An incidental radiographic film would be taken if a sponge, needle, or instrument is unaccounted for at the end a procedure and is believed to be in the patient.
