The computerized tomography scan works to create cross-sectional images of the body. The image that is created provides a piece of deeper knowledge about the body which otherwise is not possible. There are many cases in which X-rays do not work sufficiently, and so there is a need for a CT scan. Doctors perform a CT scan on the patient to clearly identify the problematic area. The images allow them to check the intensity of injury from a different perspective. The radiologist makes a complete and detailed report of ct scan results if serious or even in normal cases. CT scans provide a normal and clear report of the disease.
Reason For Doing The Test
In some serious situations, such as road accidents or identifying the problematic area of the body, X-rays do not work. To effectively know the cause of the disease and the area which is affected, CT scans are performed. The CT scan machine not only helps in providing the right diagnosis but also works in the prevention and management of the disease. In most emergency cases, it is wise to perform a CT scan on the person.
CT scan can work effectively to look for tumors and brain hemorrhage conditions. Likewise, a CT scan will let you know if any artery of the body has any blockage. The injuries related to the skeletal system are mainly diagnosed with the help of a CT scan. The problems in the abdomen are perfectly diagnosed with the help of a CT scan.
Benefits And Contraindications Involved
The most significant advantage of a CT scan is that you can get the image of the body in much less time. The images are created in a relatively shorter time that enables the doctor to start immediate treatment on patients. This also helps them to decide whether a patient needs to have surgery or not. CT scan can show you much better results than other diagnosing tools.
However, in such situations, it becomes difficult to perform a CT scan on the person. Magnetic resonance imaging (MRI) can work to give more effective results on soft tissues and bones of the body. The radiation dose in children should also be limited to a minimum so that the risk of cancer can be avoided. However, the CT scan cost is relatively lower than other diagnosing tools.
What Factors To Consider?
You need to properly prepare yourself before a CT scan. The type of the condition a patient has and the number of radiations are all important factors to consider. The timing of the test often ranges from a few minutes to several hours, depending on the condition of the patient. The type of clothing that you are wearing is also important during a CT scan. The doctor may need to expose certain areas of your body.
The patient needs to consent to the requirements of the test, and the doctor should not breach the patient’s confidentiality. In some of the CT scan procedures, you will need to limit your fluid and food intake. The usual time of fasting ranges from six to eight hours. Certain medications also need to be stopped before a CT scan due to the contrast agent in the body.
The Procedure Of CT Scan
After following certain rules and instructions, the CT scan will be performed. If a person is wearing any sort of jewelry or metal instruments, then they need to take them off. The reason is that they can affect the images which will be created by the scan. The doctor will also ask for the complete medical history of the patient to identify the risk factors involved. The person usually lies on a bed that then moves to the scanning machine.
The scanning machine then directs the radiation beams to the person’s body. The patient may receive an IV line in case of a contrast agent. The radiologists performing the scan inform the patient when they start the procedure. They also make sure that they get clear and sharp images that do not have any blurriness. The time of the scan depends on the condition of the patient entirely.
Result Of CT Scan
To interpret the results of the scan, doctors and radiologists work in close coordination. They ensure that all risks are eliminated so that they can diagnose disease in the best way. Radiologists will write the complete report of your scan to the doctor. The scans give a clear idea of the intensity of disease and damage caused to the body. Even if a scan shows some serious results, doctors think of it as good as they know the type of treatment to give.
If the scan does not show accurate results, it will be much difficult to identify the severity of the disease. The scan helps them to interpret the disease's progressive rate. In many cases, patients receive treatment after receiving the results of scans. Diseases like cancer and tumor cannot be treated if the doctor does not know the problematic area.
Risk Factors For CT Scan
Before performing a CT scan, your doctor will ask some important questions related to your health. It is the safest tool to diagnose a disease, but at the same time, it poses certain risks. During a scan, the body of the patient is exposed to certain damaging and radioactive factors. In the long run, the patient may be subjected to the risk of cancer. Similarly, if a patient is pregnant or planning for pregnancy, then they should make an informed consent. Nursing mothers can also undergo a scan as the elements do not mix with the bloodstream.
Some patients might have to face some side effects such as runny nose, constipation, vomiting, or diarrhea. The risk of cancer associated with CT scan is there, but there is very little evidence that supports it. As harmless as they can be, CT scans still have certain limitations involved. The chances of getting clear images with a scan are probably higher than a normal X-ray. The result of the scan will help a doctor to diagnose the disease and then perform the treatment accordingly. In certain situations such as accidents or tumors, the ct scan results, if serious, will help to adopt a timely treatment. This minimizes the risk of further development of disease.
