Question

A brain imaging technique in which thousands of X-ray photographs of the brain are taken and then combined to construct a cross-sectional brain picture is known as a(n):

a) MRI (Magnetic Resonance Imaging)
b) CT scan (Computed Tomography)
c) PET scan (Positron Emission Tomography)
d) EEG (Electroencephalogram)

Answer 1

The brain imaging technique described is known as a CT scan (Computed Tomography). CT scans use X-ray photographs to construct a cross-sectional image of the brain. The patient lies on a motorized platform while a computerized axial tomography scanner takes X-ray images and combines them into a two-dimensional view of the scanned area.

Step-by-step explanation:

A brain imaging technique in which thousands of X-ray photographs of the brain are taken and then combined to construct a cross-sectional brain picture is known as a CT scan (Computed Tomography). CT scans use computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body. The patient lies on a motorized platform while a computerized axial tomography (CAT) scanner takes X-ray images and combines them into a two-dimensional view of the scanned area, or 'slice'.
