Question

The imaging technique that assesses metabolic and physiological activity of a structure is called a
A) PET scan.
B) ultrasound.
C) digital subtraction angiography.
D) MRI.
E) CT scan.

Accepted Answer

PET scans use radioactive tracers to measure metabolic and biochemical activity in the body, making it the imaging technique that assesses metabolic and physiological activity of a structure. Ultrasound, digital subtraction angiography, MRI, and CT scans do not measure metabolic activity.
