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.
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.
A lumbar CT scan is particularly useful for visualizing bone structures, making it more effective for detecting fractures, bone spurs, and certain types of degenerative changes in the spine. It provides detailed images of the spinal canal and can also reveal calcifications that an MRI might not show as clearly. Additionally, a CT scan is often quicker and may be more accessible in emergency situations. However, MRI is better for visualizing soft tissues, such as muscles, nerves, and intervertebral discs.
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.
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 or an MRI
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.
A CT scan is generally better for visualizing bone structures and detecting fractures in the spine, while an MRI provides superior detail of soft tissues, including discs, nerves, and ligaments. For back problems that involve soft tissue issues, such as herniated discs or nerve compression, an MRI is usually preferred. Ultimately, the choice between a CT scan and an MRI depends on the specific condition being evaluated and the clinical context.

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.
An enchondroma is a cartilage cyst that can be found in the bone narrow. A way to detect an enchondroma is on an X-ray scan, by undergoing MRI, or PET scan.
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.
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.
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.
No. It is not a treatment it is a scan. An MRI is a Magnetic Resonance Imaging. MRI are used for imaging tissues.
An injury that affects a ligament rather than a bone is likely to be examined using imaging techniques such as an MRI (Magnetic Resonance Imaging) scan. MRI is particularly effective for visualizing soft tissue structures, including ligaments, and can help in diagnosing sprains or tears. Additionally, ultrasound may be used in some cases to assess ligament injuries.
