Marika needs to have a neuroimaging test that will track the activity of her brain, but wants to use a radioactive tracer that is more easily obtained than those used for pet. which of the following offers the best alternative based on marika's needs? a) electroencephalography (eeg)b) computed tomography (ct)c) functional positron emission tomography (fpet)

SPECT Single-photon emission computed tomography

Explanation:

SPECT is a technique that is used for tomography of the brain to know how the tissue and blood working in the brain. It shows the activity in the brain. This technique helps in diagnoses brain stroke, head injury, ischemia attack, blockage and mental illness like schizophrenia, Alzheimer's, etc.

It is an unclear imaging technique that merges with computed tomography and finds out the problem through a combination of SPECT. Before doing SPECT, an injection is injected into the blood stream. This technique is used to know the blood is flowing in arteries and veins.

answer:

d. because dr. laguardia selected a widely used measure, his study generalizes to has strong external validity. external validity has limited external validity. other applications of this measure.

the widely used measure that he applied to his experiment was the benton facial recognition test. it employed on to football players and as result, only players who suffered brain concussions did not pas this test. and although it has an external validity, it is limited because it isn't general to apply to other population.

b) the bill goes to the president.

hope this
