Question 1

how is a cat scan and an mri different?

Accepted Answer

Contrast difference: Ct uses a combination of xrays shot from multiple directions to look at differences in tissue density.  Mri uses strong magnetic fields instead of xrays to differentiate tissues and gives much better contrast than ct. Ct is typically used in the acute setting to see if there is blood or major abnormalities. Mri is a more specific exam to differentiate abnormalities such as stroke or tumor.

Question 2

how are an mri and a cat scan different?

Accepted Answer

Both show anatomy: Both ct and MRI show anatomy.  Ct does this be imaging differences in density, and MRI by looking at differences in the number hydrogen atoms in a region (proton density) and the local environment they are in.

Both are very good, but MRI is better for looking at soft tissues.

Question 3

what is the difference between mri and a cat scan?

Accepted Answer

Radiation vs magneti: Cat scan are base on analyzing pictures from passing radiation through your body

mri. Measure the effect of differents cells in a magnetic field.

Question 4

what are the differences between an mri and a cat scan?

Accepted Answer

MRI/CT: A CT scan uses x-ray radiation to generate an image.  An MRI uses magnetic fields "tuned" to the frequency of protons in the body.  Since each scan essentially measures a different property of tissues in the body, they are complementary tests.  That is why if one doesn't provide a definitive answer, often the other will be ordered.

Question 5

what's the difference , between a cat scan and an mri ?

Accepted Answer

CT vs MRI: Ct is for a hard tissue, MRI is for a soft tissue.

Question 6

what is the main difference between cat scan and mri?

Accepted Answer

CT scan uses xrays,: MRI uses magnetic resonance to render images.. Also, CT usually gives a cross sectional view while MRI gives a length like view. There is no radiation from MRI, but because it acts like a super strong magnet,metal must be removed before it is done.

Question 7

need advice on what is the the difference of an mri can a cat scan?

Accepted Answer

Big difference: Ct scans use radiation to make the images. Mri uses no radiation but instead uses magnetic fields to create images. Both use computers to reconstruct the information acquired  so that it can be useful.

Question 8

can ascities be seen on cat scan or mri?

Accepted Answer

Both: You can easily see it on both studies.  But all you need is an ultrasound.  If it's a lot, you don't need anything - just examine and feel the water in the abdomen.

Question 9

what is the difference between an mri and  a cat scan? except for the radiation factor.

Accepted Answer

Physics: The physical phenomena on which these imaging techniques are built are very different, each is best suited for different purposes. Cat scans are sophisticated x ray, they rely on the degree of absorption of gamma rays (bones, ca, other metals will contrast most). Mri is better for softer tissue imaging because it depends more on the behavior of hydrogen  atoms and h2o in the strong magnetic field.

Question 10

what is the difference in diagnostics between mri, cat scan and colonoscopy?  which one is best for identifying problems?

Accepted Answer

Depends: Mri and ct scans are noninvasive imaging techniques. They have their own inherent advantages and disadvantages, and to compare them would be too complicated here. Colonoscopy is invasive, where a camera is extended via the rectum into the colon to see what the inside of the colon looks like, usually for cancer screening.
