Quizplus · Accepted Answer

SPECT can be used to study subjects while they are performing neuropsychological tasks, which is one of its advantages over PET. A) SPECT is typically less expensive than PET, not more expensive. B) SPECT provides a three-dimensional representation, not a two-dimensional representation. C) The clearance time of the SPECT tracer can vary depending on the particular tracer used, with some tracers taking longer than 15 minutes to clear from the brain.
