The Advantages and Disadvantages of Computed Tomography

1. Introduction

Computed Tomography, also known as CT scanning, is a medical imaging procedure that uses x-rays to create cross-sectional images (often called “slices”) of the body. It is often used to diagnose diseases of the chest, abdomen, and pelvis, as well as to image the bones and joints. CT scanning is also used to guide biopsies and other procedures.

2. Computed tomography – advantages

CT scanning has many benefits. It is very accurate, and can detect even small abnormalities. It can be used to image both soft tissues and bones. CT scans are often less invasive than other types of imaging procedures, such as surgery. They can be performed on an outpatient basis, and do not require sedation or anesthesia.

3. Computed tomography – disadvantages

There are also some risks associated with CT scanning. The most significant risk is from exposure to ionizing radiation, which can increase the risk of cancer. CT scans also carry a small risk of causing allergic reactions or other side effects. In rare cases, they can also cause organ damage.

4. Conclusion

Overall, CT scanning is a safe and effective way to diagnose and treat many medical conditions. However, it is important to understand the risks involved before undergoing any medical procedure.


Computed tomography (CT) is a medical imaging procedure that uses special x-ray equipment to create detailed images, or scans, of the inside of the body. CT scanning is often used to diagnose problems with the bones, muscles, fat, and organs.

The main advantage of CT over other imaging methods is its ability to image structures in multiple planes (slices), which allows for more accurate diagnosis. CT also has a shorter exam time than many other imaging modalities.

One disadvantage of CT is that it uses ionizing radiation, which can be harmful if not used properly. Another disadvantage is that CT scans can be expensive.

CT scans are generally very accurate in detecting abnormalities or diseases; however, they are not perfect and sometimes may miss small lesions or misinterpret normal tissues as abnormal.

There is a small risk associated with exposure to radiation from CT scans; however, this risk is usually outweighed by the benefits of the scan
