A PET scan is used to detect:

A)electrical activity
B)organ density
C)glucose metabolism
D)pulmonary congestion

C) glucose metabolism

C) glucose metabolism

A PET (positron emission tomography) scan is a medical imaging technique that uses a radioactive tracer to detect and measure the levels of glucose metabolism in the body. Glucose is the primary source of energy for cells, and different tissues have varying rates of glucose metabolism. By measuring the distribution and intensity of glucose metabolism, a PET scan can help detect various conditions such as cancer, heart disease, and neurological disorders. A PET scan is not used to detect electrical activity, organ density, or pulmonary congestion.
