Question

Quizplus · Accepted Answer

CT and PET are both imaging techniques used in medicine. CT (computed tomography) is primarily used to produce detailed images of internal structures of the body whereas PET (positron emission tomography) is used to detect biological activity within the body by measuring the uptake of radioactive glucose. Thus, CT primarily involves the visualization of structure, while PET primarily involves the visualization of function. Therefore, the correct answer is that CT is to PET as structure is to function (B).
