Grade: 1User Responses: b.provides much more detail. Feedback: a.Correct.
CT scans are generally quieter and more comfortable for the patient, and faster than MRI scans. MRI Scans MRI scans utilize a combination radio frequency pulses and strong magnetic fields to capture images of the body. While MRI scanners can also be used to make images of the head, abdomen, and chest just like a CT scanner, they do not scan bone. They are particularly …
Due to the use of a magnet and radio waves, instead of radiation or the use of any form of contrast medium, MRI has a great advantage over other imaging technologies that rely on radiation and contrast mediums.

MRI gives higher detail in soft tissues. One of the greatest advantages of MRI is the ability to change the contrast of the images. Small changes in radio waves and magnetic fields can completely change the contrast of the image. Different contrast settings will highlight different types of tissue.
Advantages of CT Scan over MRI 1 CT is very good for imaging bone structures. 2 Some patients who have received certain types of surgical clips, metallic fragments, cardiac monitors or pacemakers cannot receive an MRI. 3 The time taken for total testing is shorter than taken by MRI. 4 MRI cannot be done on patients who are claustrophobic as the patient has to remain inside the noisy machine for about 20-45 minutes. 5 CT scan is cheaper than an MRI. A CT scan costs $1,200 to $3,200 while an MRI can cost up to $4,000.
CT scans are widely used in emergency rooms because the scan takes fewer than 5 minutes. An MRI, on the other hand, can take up to 30 minutes. An MRI typically costs more than a CT scan.
Cost. CT Scan costs range from $1,200 to $3,200; they usually cost less than MRIs (about half the price of MRI). MRI costs range from $1,200 to $4,000 (with contrast), which is usually more expensive than CT scans and X-rays, and most examining methods. Time taken for complete scan. Usually completed within 5 minutes.
MRI costs range from $1,200 to $4,000 (with contrast), which is usually more expensive than CT scans and X-rays, and most examining methods. Time taken for complete scan. Usually completed within 5 minutes. Actual scan time usually less than 30 seconds. Therefore, CT is less sensitive to patient movement than MRI.
Usually completed within 5 minutes. Actual scan time usually less than 30 seconds. Therefore, CT is less sensitive to patient movement than MRI. Depending on what the MRI is looking for, and where it is needing to look, the scan may be quick (finished in 10-15 minutes) or may take a long time (2 hours). Effects on the body.
The first commercially viable CT scanner was invented by Sir Godfrey Hounsfield in Hayes, United Kingdom. First patient's brain-scan was done on 1 October 1971. First commercial MRI was available in 1981, with significant increase in MRI resolution and choice of imaging sequences over time. Image specifics.
