What Is Lung Ct Scan & How Does It Work?

 A lung CT scan is a medical imaging test that uses advanced technology to create detailed images of the lungs. This test is commonly used to diagnose and monitor lung diseases, such as lung cancer, emphysema, and pneumonia. In this blog, we will explain what a lung CT scan is, how it works, and what to expect during the procedure.

What is a Lung CT Scan?

A lung CT scan, also known as a chest CT scan, is a non-invasive medical imaging test that uses X-rays and computer technology to create detailed images of the lungs. The test involves lying down on a table that moves through a large, doughnut-shaped machine called a CT scanner. As the table moves through the scanner, X-rays are emitted and detected by sensors on the other side of the scanner. These sensors produce multiple images of the lungs, which are then combined by a computer to create a detailed 3D image.

How Does a Lung CT Scan Work?                      

A lung CT scan works by using X-rays to create images of the lungs from different angles. The X-rays are produced by a machine called a CT scanner, which consists of a large ring-shaped machine with a table that moves through it. As the table moves through the scanner, X-rays are emitted from the machine and detected by sensors on the other side of the scanner. The sensors produce multiple images of the lungs, which are then combined by a computer to create a detailed 3D image.

Before the procedure, you may be asked to change into a hospital gown and remove any metal objects, such as jewelry or belts. You may also be given a contrast dye, which is a liquid that helps highlight certain areas of the lungs. The contrast dye is usually injected into a vein in your arm before the scan.

During the procedure, you will lie down on the table and the technician will give you instructions on how to breathe and when to hold your breath. The table will then move slowly through the CT scanner while the X-rays are being emitted. You may hear whirring and clicking noises during the procedure, but you should not feel any pain.

After the procedure, you can usually return to your normal activities immediately. The images will be sent to a radiologist, who will analyze them and send a report to your DiagnosticCentre In Byculla.

What are the Risks of a Lung CT Scan?

A lung CT scan is a relatively safe procedure, but there are some risks involved. The most common risk is exposure to radiation, which can increase your risk of cancer over time. However, the amount of radiation exposure from a lung CT scan is typically low and not a cause for concern. If you are pregnant or think you may be pregnant, you should inform your doctor before undergoing a lung CT scan, as radiation can harm a developing fetus.

Conclusion

A lung CT scan is a useful medical imaging test that can help diagnose and monitor lung diseases. The procedure involves lying down on a table that moves through a CT scanner, which produces detailed images of the lungs using X-rays and computer technology. While there are some risks involved, the benefits of a lung CT scan often outweigh the risks, especially for people with suspected lung diseases.
