Question

Quizplus · Accepted Answer

The test that Ricardo's neurologist will be using is a positron emission tomography (PET) scan, as it involves injecting radioactive chemicals into the bloodstream to produce images of the brain. A CT scan and MRI scan use different methods to produce images of the brain, without the use of radioactive chemicals. Electrical stimulation of the brain (ESB) is a different type of neurological test that involves directly stimulating the brain with electrical impulses.
