What's the difference between an MRI, a CAT scan, and a CT scan?
Answer:
Magnetic resonance imaging (MRI) uses radio frequency waves and a strong fascinating field a bit than x-rays to provide remarkably clear and detailed pictures of internal organs and tissues. A ct scan and cat scan are the same entity a CT scans of internal organs, bone, soft tissue and blood vessel provide greater clarity than conventional x-ray exams.
The CAT in CAT Scans comes from "Computerized Axial Tomography." 'Axial' money that it makes slices surrounded by the horizontal plane (like slicing the top half of someone away from their bottom half). While axial slices are still the most adjectives ones used, the cat scan machines today are able to breed slices in lots different planes, so it doesn't make sense to give the 'A' in CAT in this day and age.
CAT Scans make pictures base on DENSITY. More dense things look white (like bones) and less dense things look obscurity (like air surrounded by the lungs).
