CT scan & MRI scan are two different methods that help create a detailed image of internal body parts such as bones, joints & organs. Doctors order CT & MRI scans to diagnose various medical conditions. Both types of scans have similar use as they produce images differently. CT scan uses X-rays, whereas MRI scan uses strong magnetic fields & radio waves. CT scans are more common & less expensive, but MRI scans produce more detailed images as we look at the differences between Ct & MRI scans and their uses, procedure & safety. Vital Radiology provides Teleradiology UK & is one of the best second opinions on CT & MRI scans. 


What are they?

CT scans & MRI scans are two ways of creating detailed images of internal body parts. Doctors then analyze the images to detect abnormalities such as bone fractures, tumours on organs or joint damage. So people refer to CT scan, also known as CAT scan, which refers to a computerized axial tomography. During a CT scan, a person lies down & large X-ray machine known as a CT scanner

sends images to the computer. Whereas MRI stands for magnetic resonance imagery, these scans use radio waves & magnets to create images. During an MRI scan, a person lies down in an MRI scanner. This machine makes constant magnetic fields & uses radio waves to bounce off water molecules & fat cells in the body. The scanner also sends images to the computer. CT scans are more common & less expensive than MRI.
