CT scans include all the advantages, medical advantages and dangers they might bring. CT scan is an abbreviation of Computed Tomography scan. It uses X-rays and a computer to get a set of images that show the body’s inside structures, organs, bones and tissues. By using radiation at different angles, the CT machine collects the information to make a 3D structure out of it and these 3D images are called slices. Parts of the brain are examined and cut to understand three-dimensional images for better detection of different issues.
The CT scan device is made up of a large gantry which is shaped like a donut. In this gantry is an X-ray source that spins around inside to deliver radiation to create images of your body. CT scan machines use a flat bed; you must lie on it as it enters the gantry, while the X-ray source spins in the gantry above you and fires several narrow beams of radiation throughout your body. There is a set of radiation detectors in the CT scanner that is located opposite the X-ray source, collecting the rays above your body. During each rotation, there is a process that makes a single 2D slice and the thickness can differ depending on the type of machine and Ganesh Diagnostics provides the best 128-slice scanners which cover larger regions even faster than 16-slice and 64-slice scanners.
It can clearly show any issues that occur in your body’s organs such as lesions or injuries. Being used for screening, a CT scanner plays a significant role when trying to diagnose cancers and possible tumours. Due to its prompt and accurate action, computed tomography is most often applied when any emergency occurs. It is used to assess the organs if a person has an injury, stroke due to clots, bleeding or chronic conditions like cancer.
The term CT scan can mean something else, depending on what it is testing for.

- Image of bones with a CT scan
- CT scan of the Brain/ CT Head
- CT Scan of the Chest/Chest CT/Lung CT

- Scan of the neck and spine
- Cardiac CT
- Scan of the kidneys using computed tomography
At times, when better pictures are essential to diagnose and check up on already known lesions and diseases, the use of a Contrast agent is beneficial. Usually, the contrast is injected through your arm or hand which distributes it among the cells throughout your body so abnormal areas can be seen more clearly,
Mentioning the dangers linked to a CT scan, especially compared to the benefits it has in medical diagnosis, is never unnecessary. The risks present from any scan are lowered more by always carrying out the scan under safety measures. The principle guiding radiation-based scans is called ALARA which is short for “As Low As Reasonably Achievable” and its main elements include time, distance and shielding. All the recommended safety measures are in place at the top diagnostic centre for CT scans to avoid high radiation levels. Radiations can change your genes which might eventually result in cancer, however, since the probability of developing cancer after a single scan is so low and with proper use of CT, these chances can be decreased. At first, allergic reactions appear as itching, redness and swelling and in the worst cases, it may progress to headache, dizziness, nausea, vomiting and anaphylactic shock. This is the reason you should directly call your doctor immediately when you have your first signs of an allergy.
