In which brain imaging method is the patient drunk or injected with a substance called2-DG?a) FMRIb) MRIc) DTId) MEGe) PET

The correct answer is e) PET (Positron Emission Tomography).

In PET scans, a radioactive glucose analog known as 2-deoxyglucose (2-DG) can be injected into the patient. This substance helps to measure metabolic activity by tracking how glucose is used in the brain. When the brain is active, it consumes more glucose, and the injected 2-DG substance will accumulate in those active areas. Although the patient is not actually “drunk,” the term may refer to the fact that the patient is under the influence of the radioactive tracer.

PET scans are valuable for various medical applications, including research on brain disorders, cancer, and evaluating the effects of treatments.
