The discovery of X-ray has opened a new horizon in the field of medical science. It was X-ray which had given way to a new category by the name of radiology in the field of medicine. With changing times the subject of radiology has already branched out into several other diagnostic categories including Digital X-ray, Ultrasonography, Colonography, MRI, Mammography and so on and so forth. This article would be taking up one of the processes name CAT or CT scan and it would be discussing about the process through the following lines.
An Intro to CT
The computed axial tomography is one process in the sphere radiology through it multifaceted application has affected a variety of fields. The main purpose of this particular method is to diagnose factors like illness, internal injuries and any kind of anomaly which is present within the body. Involving quite a moderate level of radiation, this process helps in generation of multiple images within the body and it is being combined into a cross sectional 3D images. Structures of bone, blood vessels as well as soft tissues.
There are several benefits of CT scans over that of the traditional X-rays. These scans can go reach those places where traditional X-ray cannot. This type of scan as a diagnostic process has revolutionised the ways medical practitioners used to practice.
History of the CAT
CT scan has been the brainchild of two British engineers, namely Dr. Alan Cormack and Godfrey Hounsfield. Way back in the 70s, these engineers were able to photograph images of the internal portion where general X-rays wouldn’t have reached. With changing times the process has improved and it is able to generate reports much faster along with giving much accurate reports which will help people to diagnose.
Areas which are covered under CT scan
It has been already stated in the aforementioned lines of this article that the subject of CT scan has been extensively in medical science. Doctors without resorting to invasive surgery can take a quick scan to reveal their disease. The main areas which can be covered by CT scan includes diagnosis of cancer, detection of bone injury and spine injury, chest and abdomen examination as well as cardiovascular disease diagnosis for detecting obstacles within the blood vessels.
CT scan encompasses the area of neck, brain, chest, spine, abdomen, sinuses and other crucial areas of the human anatomy. The CT scan is the perfect tool which helps in finding every intricate details of the body without any kind of invasion.
CT Scans Similarities
CT scans have got several similarities with another process namely MRI or magnetic resonance imaging. The biggest difference between the two processes is that, in case of MRI, the process involves the use of magnets and radio wave to acquire the image, where as CT or Computer Tomography mainly uses radiation. This process of scanning is a much preferred options for doctors for the diagnosis of cancer, internal hemorrhage, or abdominal contraction, the process of MRI is much focuses on the density of the body. The whole process focuses on the ligaments and the muscles, the density of the spinal column or any anomaly within the brain.
The Results of the Scan
The scans are achieved in 64 or 128 slices, which are accumulated to make one 3d image of the section of the body having its CT scan. The newer avatar of the scanners comprises 8 times more the slices of the previous versions.
Risk of CT scan
Due to an excess percentage of radiation emitted due to the radiation there is possibility of children developing cancer at a very early age. A research conducted by seven healthcare systems in the US came up with the fact there has been a tendency of developing solid cancer in younger female patient especially those patients who have received CT scan in the pelvic and the abdomen regions.
