Question

question 46 2 pts magnetic resonance imaging (mri) is a technique that: measures the rate at which brain cells use glucose. constructs a three - dimensional image from x rays. transduces the electrical activity of individual neurons. constructs images of a persons tissues and biochemical activities.

Explanation:

1. Analyze each option:

• Option 1: Measuring brain cell glucose use is done by PET (Positron Emission Tomography), not MRI.
• Option 2: Constructing 3D images from X - rays is CT (Computed Tomography), not MRI.
• Option 3: Transducing electrical activity of individual neurons is done by techniques like EEG (Electroencephalogram) at a more macro level or invasive methods for single neurons, not MRI.
• Option 4: MRI uses magnetic fields and radio waves to construct images of a person's tissues and can also provide information about biochemical activities in some cases.

Answer:

D. constructs images of a person's tissues and biochemical activities.
