What is the difference between CT and MRI scan?

What is the difference between CT and MRI scan?

Mechanism: Mri is based on the spin-spin splitting of hydrogen atoms inherent to all bodily tissues, namely in the form of water. The raw data produced from an MRI scan must undergo extensive processing to be converted into a "readable" image. Ct scans are essentially fancy x-ray machines which can take "slices" of whatever is being examined (head, abdomen, chest, etc.) unlike mri, ct uses ionizing radiation. ...Read more

Computed Tomography (Definition)

Ct uses xrays taken an 360 degrees combined with a computer to see"inside" the body. The table moves as the xray tube and detectors spin around the patient 10 times a second or more! the image shows excellent soft tissue detail, enhanced with injection of intravenous contrast or oral contrast. This way the body is shown in slices, in any plane, usually axially, but ...Read more

What is the difference between an MRI scan and a CT scan?

MRI vs CT: MRI creates images from manipulation of strong magnetic fields, CT uses ionizing radiation just like xrays. CT is much faster and allows for a large survey of parts of the body. MRI is more suitable for evaluating more specific tissues (heart, brain, joints) Each has their own advantages & disadvantages and largely depend on what is being assessed. Always confer with a radiologist! ...Read more

What's the difference between the CT head the MRI brain scan?

What's the difference between the CT head the MRI brain scan?

CT vs MRI: Ct's and mris can focus on different things. Ct is typically used to view bone and look for bleeding while mris are used to view tissues. Also, cts use radiation similar to xrays while and MRI does not expose the patient to any radiation. However, anyone with a magnetic metal in their body can not get an mri, since MRI uses a large magnet. ...Read more

Wanted to know if discount ct/mri scan diagnostic centers give a poorer service quality?

Wanted to know if discount ct/mri scan diagnostic centers give a poorer service quality?

Sometimes: It is hard to answer. The imaging is dependent on many factors including the equipment, the tech performing the scan, and the interpreting physician. Any breakdown in that system leads to poor results. ...Read more

Docs, could a CT or MRI scan be done anonymously?

Anonymous: Your medical record is confidential, other than regulatory/legal requirements, can't be released without your consent.It would be a violation of ethics and federal law. At my hospital, it is grounds for immediate termination. A legit facility won't scan you anonymously. If your doctor wants you to have a scan, if you can, go one town over where you are not known, if you are not comfortable local. ...Read more

Could a CT scan show anything a MRI scan cannot ?

Yes: Some Doctors who interpret MRI exclusively in their practice will promote the idea that MRI is the best imaging technique for every condition. To a lesser extent, some Doctors will say CT. Some doctors swear by Ultrasound imaging. There are strength and weaknesses of each modality, with considerable overlap in information produced. And each modality has some advantage over others. ...Read more

Can MRI scan be used for chest rather than CT scan? Which one is better?

That depends : That would depend on what one was looking for. For most instances, ct is better, inspire of the radiation. Just keep the number of these tests to what is really needed. ...Read more

Mri (Definition)

Mri or magnetic resonance imaging is one of the more recently developed imaging modalities available to physicians. It uses powerful magnets to generate images. There is no ionizing radiation which is a major advantage over many other modalities. Mri is the best imaging exam that we have for most soft tissue and joint related problems. There are radiologists ...Read more
