If one wanted to examine changes in the levels of various brain metabolites following a concussion,one could use:
A) Diffusion tensor imaging (DTI).
B) electrocardiogram (ECG).
C) Positron Emission Tomography (PET).
D) Magnetic resonance spectroscopy (MRS).

Question

Quizplus · Accepted Answer

Magnetic resonance spectroscopy (MRS) is the best choice for examining changes in the levels of various brain metabolites following a concussion. MRS can measure the concentrations of various metabolites in the brain, such as N-acetylaspartate (NAA), creatine, and choline. Changes in these metabolites can provide valuable insights into the extent and severity of a concussion and its effects on brain function. Other imaging techniques such as DTI and PET may provide useful information about structural and functional changes in the brain after a concussion, but they do not directly measure changes in brain metabolites. ECG is a test used to evaluate the electrical activity of the heart and is not relevant for examining changes in brain metabolites.
