CT and MRI (what is the difference) In order to be healthy, you need not only to lead a healthy lifestyle. It is very important to undergo a medical examination in a timely manner, which involves, first of all, the use of various diagnostic techniques. The ability to prevent the development of the disease depends on the accuracy of the diagnosis, and if it is available, the success of treatment. CT and MRI – modern diagnostic methods. One of the most popular diagnostic methods in the modern world for doctors around the world are: MRI (magnetic resonance imaging) and CT (computed tomography). A person turns to these painless (non-invasive) methods for the timely detection of various pathologies in his body, disorders in his state of health. A little about the studies themselves, about their similarities and differences. Both tomographies, as procedures, are identical: the patient is placed on a mobile table and his body is scanned in layers (viewed). The results in the form of images are displayed on a computer monitor. Then experts “decipher” them, make a preliminary diagnosis. Or, if you want, a verdict is issued. That’s all the similarities between studies. But the differences should be discussed in more detail so that a person consciously approaches the choice of tomography method. So what is the difference and what should be preferred MRI research is based on the use of a magnetic field that does not irradiate a person, and therefore is considered not dangerous to his health. CT is based on the use of x-rays. And it is universally considered harmful to human health. In general, CT is the same X-ray. That is, MRI and CT differ in research methods. That’s all. There are still nuances in the time of the study, in the indications, contraindications and in price.
- 1. The MRI procedure takes more than an hour, the CT scan is performed in a matter of minutes.
- 2. MRI is not accessible to a person who has in his body any objects made of metal (fragments of warheads, for example, or a plate in the skull). CT is prohibited for women “in an interesting position”, “nursing” mothers, children (only in rare cases), and the rest of the categories should not undergo the procedure too often;
