Know now what is the difference between tomography and mri

Confusion between the exams is common, as both use modern technologies to non-invasively obtain internal images. That is, they show organs and other tissues without the need for any surgery or cutting, in a very safe way. But that doesn’t mean that computed tomography (CT) and magnetic. Resonance imaging (MRI) employ the same technology , as I show in the next few lines. Read until the end and check out the contribution of telemedicine to the quick issuance of the results of these exams. What is the difference between tomography and MRI? As I mentioned in the introduction to this text, it is natural to confuse CT and MRI . Mainly for those who do not know details of the equipment used in these radiological examinations . Basically, the tomography device or CT scanner combines a rotating tube with X-ray beams to produce a type of internal photograph of the observed area.

What is the difference between tomography and MRI?

While the resonance equipment uses a magnetic field and radio waves to provoke reactions in the hydrogen atoms, capturing the images. Another difference is in the contrast adopted for each procedure. Contrast is a compound that highlights a certain part of the body , such as blood vessels and organs. I talk more about the differences – and similarities – between MRI and CT below. What is tomography? Tomography is an imaging test that uses ionizing radiationand Macedonia Mobile Number List a rotating tube to collect cross-sections of a region of the body. The tomograph is an evolution of the X-ray equipment , with the advantage of obtaining several radiographs in a single procedure. These images can be superimposed, forming 3D structures . The procedure works like this: the patient lies down on the stretcher of the tomography device, which is turned on, emitting X-ray beams. This radiation is directed to the studied area.

What is tomography?

Dense tissues absorb most of the rays. While softer ones let a lot of radiation through. Then, the remaining rays hit a photosensitive plate, generating images in black. White and grayscale. Bones and other hard parts are seen in white , while organs. Cartilage and muscles appear in shades of gray. Air, on the other hand, appears black Mobile Numbers in tomographic images. If it is necessary to demonstrate soft tissue, computed tomography can be performed using iodine-based contrast. Magnetic resonance imaging is a diagnostic method that uses radio wavesand a magnetic field to produce high-resolution images. At the time of the exam, the patient must also lie down on a stretcher that slides into the MRI tube. The equipment has a large magnet, responsible for the formation of the magnetic field as soon as it is turned on. Thus, the field exerts influence on materials with a magnetic.
