CT scans utilize X-rays to produce images of the inside of the body while MRI (magnetic resonance imaging) uses powerful magnetic fields and radio frequency pulses to produce detailed pictures of organs and other internal body structures.
A CT (computerized tomography) scan is a combination of a series of X-ray images taken at different angles; the CT uses a computer to create images from these X-rays.
An MRI (magnetic resonance imaging) is a scan that uses magnetic fields and radio waves to produce a detailed image of the body’s soft tissues and bones.
How does a CT scan (cat scan) work?
A CT scan works by taking multiple X-rays at various angles and then utilizes those X-rays to form a three-dimensional image of whatever organ system is being examined. A computer examines all of the various X-rays taken at different angles and synthesizes the images to form a three-dimensional computer model of internal organs.
