A CT scan is a computer-assembled set of X-rays taken from different vantage points. The computer can create 3D models of whatever it images, but the nature of X-ray imaging is that it is more effective for denser tissues (bone), than soft-tissues (organs or blood). There are new CT techniques that can help image organs (the heart is of particular interest), but MRI is generally capable of imaging soft tissues with greater detail. MRI is more frequently used for neurological imaging, and can be used to do chemical analysis of tissues (spectroscopy) inside your body non-invasively.
Because they use very different means to image, both CT and MRI can 'miss' things that would better show up on the other modality.

∙ 10y agoThis could be a huge answer....
Some patients can not enter an MRI scan due to being claustrophobic or having implanted devices not compatible with MRI.
There are also some things that either the CT or the MRI may see that the other machine might not. I have seen tumors that MRI could not detect that CT did and also some that CT didn't detect that MRI did. That is why your doctor may do multiple tests to find all anomalies.
There are also many differences to what parts of the anatomy and abnormalities that each machine can see best.

∙ 12y agoMRI (magnetic resonance imaging) uses extremely powerful magnets thus not using any ionizing radiation. CT (computed tomography) typically is faster (at least for me) and many times involves injections or swallowing of contrast material. I'm sure a person with medical background can answer this question better - hopefully they can do so without typing in this paragraph.

Is it better to get an mri or ct scan of your elbow?
It depends on what the problem with the elbow is. If it is a bone related injury then the CT scan will show more detail but if the problem is with the muscles or ligaments, then the MRI Scan will be more useful.
Is it possible to have a MRI body scan with a defibrillator fitted?
no it is not possible to have an MRI scan because the dfibrillator is dirupted by magnets and that is what an MRI is, a giant magnet.
Is a bone scan better than an MRI scan?
A bone scan, or x-ray is simply a different type of scan than an MRI. No kind of scan is better than another, it simply depends what the scan is trying to ascertain.
Which is the first imaging method to examine the heart?
A CT scan or an MRI
What is better ct scan or a mri?
Both and neither. They each have areas of the body they are better at. Many DR's think the MRI is better because they think it is newer, but both machines have been around since the late 60's.
Does a contraceptive implant show up on an mri scan?
Yes, contraceptive implants show up on MRI.

If someone has more than one MRI scan would you use MRIs or MRI's?
MRIs == ==
What is the average cost of a pet mri scan?
It was estimated that to do an MRI for my cat would cost approximately $1800.
How much does it cost for a checkup at MRI scan and CT scan center?
A CT scan is about $300 to $6750, while a MRI scan is $400 to $12,000.
Is it possible to have a MRI body scan with a defibrillator fitted?
no it is not possible to have an MRI scan because the dfibrillator is dirupted by magnets and that is what an MRI is, a giant magnet.
Which technology would be best in locating soft tissue injuries?
MRI SCAN
Is a bone scan better than an MRI scan?
A bone scan, or x-ray is simply a different type of scan than an MRI. No kind of scan is better than another, it simply depends what the scan is trying to ascertain.
What would happen if people over 40 had an MRI scan?
It shows what is inside of us.
What advantage does the MRI scan have over the Pet scan for the subject?
A PET scan shows what level / stage (if any) the cancer is at. An MRI scan doesn't do this, the reader, looks for abnormalities on the scan which shows up everything in the body.
Is a MRI a treatment?
No. It is not a treatment it is a scan. An MRI is a Magnetic Resonance Imaging. MRI are used for imaging tissues.
Does an EEG show brain tumor?
Only a MRI can tell for sure
