Where can folks get more details about CT? What’s computed tomography? Computed tomography (CT) is a noninvasive imaging procedure that uses special x-ray gear to create detailed photos, BloodVitals SPO2 or scans, BloodVitals SPO2 of areas inside the body. Each picture created throughout a CT process shows the organs, bones, and other tissues in a thin “slice” of the body. Your complete series of photos produced in CT is sort of a loaf of sliced bread-you possibly can take a look at every slice individually (2-dimensional pictures), or you can have a look at the whole loaf (a 3-dimensional image).

Computer packages are used to create both types of photos. Modern CT machines take continuous photos in a helical (or spiral) fashion somewhat than taking a collection of pictures of particular person slices of the physique, BloodVitals SPO2 as the unique CT machines did. Helical CT (additionally called spiral CT) has several advantages over older CT techniques: it is quicker and produces better high quality 3-D pictures of areas contained in the physique, which may improve detection of small abnormalities. As well as, CT is broadly used to assist diagnose circulatory (blood) system diseases and situations, similar to coronary artery disease (atherosclerosis), blood vessel aneurysms, and blood clots
