A) Carbon-14, Nitrogen-13, Oxygen-18.
B) Technetium-99m, Iodine-123, Gallium-67.
C) Fluorine-18 FDG, Carbon-11 acetate, Oxygen-15 water.
D) Rubidium-82, Indium-111, Thallium-201.

Answer 1

The FDA-approved PET tracers are Fluorine-18 FDG, Carbon-11 acetate, and Oxygen-15 water.

Step-by-step explanation:

The FDA-approved PET tracers are:

• Fluorine-18 FDG - used to detect cancer
• Carbon-11 acetate - used for imaging cardiac metabolism
• Oxygen-15 water - used to measure blood flow

These tracers are commonly used in positron emission tomography (PET) to study various physiological processes in the body.
