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.

∙ 9y agoBoth procedures are generally safe. A CT (computerized tomography) scan uses X-rays, but at a dose low enough to be generally harmless. An MRI (Magnetic Resonance Imaging) scan uses magnetic fields rather than X-rays, and we're not aware of any harmful effects of powerful magnetic fields.
However, an MRI can be incredibly NOISY, and continuous exposure can damage your hearing. This is a ridiculous example, but if two people were placed inside the machines for long periods of times, the guy in the MRI would go deaf before the guy in the CT scan was sickened by radiation.

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.
Can you have a ct scan when got a difibrillator?
Yes. It is safe in a CT. Ask about the policy if getting an MRI.
Which is the first imaging method to examine the heart?
A CT scan or an MRI
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.
Can an MRI scan miss what a CT scan would show?
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.

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 a cat scan or an mri more accurate at detecting brain aneurysms?
A CT Scan can image an aneurysm without a contrast injection even though it does better with a contrast agent. An MRI will require an contrast agent or an MRI/MRA.
Can you have a ct scan when got a difibrillator?
Yes. It is safe in a CT. Ask about the policy if getting an MRI.

How are neuronal migration disorders diagnosed?
Diagnosis is usually made by neuroimaging. CT scan or MRI of the brain will show the characteristic abnormality. MRI has better resolution and may detect polymicrogyria or small heterotopias more easily than CT.
Why is a MRI scan better then a ultra sound?
CT scanning uses radiation while MRI does not
How can adrenal tumors be imaged?
can be imaged very well with a CT scan or MRI, and benign tumors tend to look different on these tests than do cancerous tumors. Surgeons may order a CT scan, MRI, or scintigraphy
Why is an MRI better than a mammogram?
it produces better images of soft tissues - apex
What does low density mean in a CT scan?
I had a low density undetermed spot by my lower right ear shown on a ct scan of the sinus. What are they looking for to do a MRI of the head.
What MRI misses that CT scan shows?
The classic answer is acute sub-arachnoid hemorrhage.
