What are the differences between Catscan and MRI?

Question

Websites to back you up, please.

Answer 1

what this is saying is that cat scan take pictures of your insides like your stomach,heart and other organs

CT or CAT scan
A computed tomography (CT) scan uses X-rays to make detailed pictures of structures inside of the body.

During the test, you will lie on a table that is hooked to the CT scanner, which is a large doughnut-shaped machine. The CT scanner sends X-ray pulses through the body. Each pulse lasts less than a second and takes a picture of a thin slice of the organ or area being studied. One part of the scanning machine can tilt to take pictures from different positions. The pictures are saved on a computer.

A CT scan can be used to study any body organ, such as the liver, pancreas, intestines, kidneys, adrenal glands, lungs, and heart. It also can study blood vessels, bones, and the spinal cord.

An iodine dye (contrast material) is often used to make structures and organs easier to see on the CT pictures. The dye may be used to check blood flow, find tumors, and look for other problems. Dye can be put in a vein (IV) in your arm, or you may drink the dye for some tests. CT pictures may be taken before and after the dye is used.

and a mri is a better way to look at things you cant see in a cat scan if they missed somethin or cant see

A magnetic resonance imaging (MRI) is a test that uses a magnetic field and pulses of radio wave energy to make pictures of organs and structures inside the body. In many cases, MRI gives information that cannot be seen on an X-ray, ultrasound, or computed tomography (CT) scan.

For an MRI test, the area of the body being studied is placed inside a special machine that is a strong magnet. Information from an MRI can be saved and stored on a computer for more study. Photographs or films of certain views can also be made. In some cases, a contrast material may be used during the MRI to show pictures of organs or structures more clearly.

Answer 2

cat-scan (CT) scan is in two dimensions and MRI ( magnetic resonant Imaging) is in three detentions. CT uses X ray radiation and MRI uses magnetic electron Imaging In conjunction with radio wave pulses of energy, the MRI scanner can pick out a very small point inside the patients body and ask it, essentially, "What type of tissue are you?" The point might be a cube that is half a millimeter on each side. The MRI system goes through the patients body point by point, building up a 2-D or 3-D map of tissue types. It then integrates all of this information together to create 2-D images or 3-D models.

MRI provides an unparalleled view inside of the body

Answer 3

CT uses X-rays. MRI uses a strong magnet and pulsed radio waves to excite certain electrons which leads to a measurable signal.

Answer 4

CAT scan expanded -computerised axial tomography uses X-rays to picturise organs in different planes.Bones are picturised. better than soft tissues . MRI is magnetic resonance imaging , uses sound waves and their resonance to picturise any part and more useful and has no X-ray irradiation effects..Soft tissues not bones picturised well .

Answer 5

CAT scan or CT scan is a type of x-ray. See http://en.wikipedia.org/wiki/CT_scan

MRI uses a strong external magnetic field to excite atomic resonances; no x-rays. See http://en.wikipedia.org/wiki/MRIhttp://en.wikipedia.org/wiki/MRI
