Medicine today is using a series of tests to make the right diagnosis. There are a lot of tests that are applied on a patient to make sure the doctors do not miss out a single thing which can lead to a compromise on patient’s health. In this article we are going to discuss what is a CT and MRI scan.
What is a CT scan?
A CT scan uses combinations of many x-ray images of a patient to see the inside of the body without cutting into anything. It eliminates superimposition of the images outside the area of interest. It is regarded as a radiation diagnostic technique. The use of CT scan has brought a lot of benefits to the world of medicine. Using radiations through a CT scan machine provides doctors with the detail of all the internal injuries of a patient. This way a lot of time is saved which was earlier used to detect the damage to the body in case of an accident. Now doctors can reach the exact point of injury and start the treatment as soon as the diagnosis is made.
What is an MRI scan?
Some people confuse an MRI and CT scan. They think it is one and the same thing, but no there is a huge difference between the two. In an MRI, the medical imaging technique is used to create pictures of the anatomy of a human being. It also shows the physiological processes going on in the body. Strong magnetic fields, field gradient and radio waves are used in MRI scanners to generate images of the body.
So, when it comes to what is a CT and MRI scan, there is a huge difference. CT scan is done in 5 minutes and is usually available in emergency centers of the hospital while MRI needs a longer time and you need to go to a lab or an MRI center to get it done.
