CT scan is the abbreviation for computerized tomography scan. This scan uses images taken by a computer and an X-ray machine. A final cross sectional image is generated with the help of the pictures taken in these two ways. Thus the image generated gives a pinpointed result for any problem. Thus CT scan helps to get an exact idea and location of the actual problem in the body. This scan is helpful to detect problems with almost all types of body parts, including soft tissue, blood vessels, and bones. This test doesn’t require any type of blood sample or an oral swap like the antigen fit to fly test. A patient just needs to lie on a platform and the machine does the rest of the work automatically.
What is the need for a CT scan?
Through this scan, we can detect an injury, damage, or deformity at any place in the body. Your doctor may recommend your CT scan when –
- When a bone in your body breaks or there is a tumour in the muscle etc.
- To find the precise location of tumour, infection, or blood clot.
- Determine the progress of the severe diseases, such as cancer, heart disease, lung and liver disease.
- To detect any internal bleeding.
This type of scan is useful for patients suffering from brain trauma or tumours. The results can determine if a person is capable of flying or not. Any person that has symptoms of the above-mentioned ailments should opt for a CT scan for a quick and precise result. Especially if they are planning to fly to someplace in the near future. This is equally important as taking an antigen fit to fly test to check for corona infection.
Precautions and Dangers
What is essential to know before getting a CT scan?
CT scan is not considered safe during pregnancy. Only an expert doctor can decide based on the emergency if a pregnant woman should have a CT scan or not. Although the CT scan radiation does not affect the baby. To be on the safer side the doctor might recommend tests like ultrasound and MRI instead of CT scan. CT scan is safe and there are reports that show that there are no side effects of CT scan with low radiation on humans. Some patients might feel a burning sensation due to high-intensity radiation. Some patients might witness a metallic taste in the mouth, and a feeling of heat, which goes away on its own after some time. If the symptoms persist for long then more tests can help determine the exact cause.
There are also some dangers of CT scans. Prolonged radiation exposure from a CT scan can cause cancer. It is a known fact that frequent CT scans and X-rays can increase the risk of cancer. Children who have multiple chests and abdominal X-rays and scans are especially at high risk.
How to prepare for a CT Scan?
For contract and clear imagery, a specific type of dye is used. The use of this dye is to highlight the areas during a scan or x-ray. Some patients might be allergic to the dyes. In such a condition, the doctor may give some medicines to avoid the reaction. But CT scan is not possible without the dye. Dye or contrast is given in the body in two ways. It can be injected into the veins through injection or the patient can orally inject the dye. The dye might taste like chalk. The dye is safe and it passes out of the body with the stool on day 2. It is important that the patient drinking the contrast should not eat or drink anything for the next 4 hours.
For patients suffering from diabetes, it is important to inform the doctor beforehand. Diabetes patients usually take drugs like metformin which might interact with the dye. Apart from these few precautions, there are no other preparations that a patient needs to do before the scan. It is safe and yields flawless results. There are many patients from third-world countries who come on sponsored visits to the UK for good quality CT scans and treatment of chronic and unique diseases. Such patients will now have to undergo a 10-day mandatory quarantine. Day 2 & 8 PCR testing is required to check for any coronavirus infection. Therefore, the doctors and labs with the CT scan facilitates will now have to keep the days’ gap in consideration before fixing an appointment for such patients.
What happens during a CT scan?
There is no pain in a CT scan. Through new technology, it takes only a few minutes to complete the scanning process. The patient has to wear a hospital gown and remove all types of ornaments. The patient has to lie on a platform that moves in and out of the machine via a slider. The slider moves up a bit during scanning. After this, the X-ray machine moves around your body. In each rotation, the machine captures dozens of images. The radiologist then studies the CT scan images and updates the physician. The physician can then move ahead with the treatment. You can get back to your routine life immediately after the scan. You can also board a flight immediately after a CT scan if you have cleared the antigen fit to fly test.
CT scan has proved to be one of the best medical technologies that have saved millions of lives by detecting the problem. CT scan also proved to be helpful to detect corona infection in asymptomatic patients.
