Question
which one of these are not true about PET?a) mostly for humans.b) the patient drinks or injected with a radioactive substance (2-DG).c) it measures the metabolic activity in the brain.d) has neuromagnetomers that contains SQUIDs.e) 2-DG has short lifetime.
Solution
The statement that is not true about Positron Emission Tomography (PET) is:
d) It has neuromagnetometers that contain SQUIDs.
Explanation: PET does not use neuromagnetometers or SQUIDs (Superconducting Quantum Interference Devices). These are used in Magnetoencephalography (MEG), not PET. PET works by detecting gamma rays emitted indirectly by a positron-emitting radionuclide (tracer), which is introduced into the body on a biologically active molecule.
