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.
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.
Yes. It is safe in a CT. Ask about the policy if getting an MRI.
A CT scan or an MRI
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.
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.

A CT scan is about $300 to $6750, while a MRI scan is $400 to $12,000.
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.

A CT scan or an MRI
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.
it produces better images of soft tissues - apex
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.
The classic answer is acute sub-arachnoid hemorrhage.

A CT scan, yes. An MRI scan- maybe. It will depend on information from the manufacturer of the device you have implanted. Most are not affected by an MRI, but that is up to medical staff to determine.
