Computed tomography, also known as CT (from Computed Tomography), is an advanced medical imaging technique that allows doctors to visualize the internal structures of the body. Computed tomography of the chest is a specific type of this examination, focusing on structures within the chest, such as the lungs, heart, blood vessels and mediastinum. In this article, we will discuss what a chest CT scan is and how it is used in medicine.
What is a CT scan?
CT is an imaging technique that uses X-rays to create detailed cross-sectional images of the body. A CT consists of a series of X-ray images taken from different angles, which are then processed by computer to create three-dimensional images of body structures.
How does the examination work?
During a chest CT scan, the patient lies on a special table that slides through a large ring-shaped device. The patient must lie still, and may sometimes be asked to hold his or her breath for a few seconds. The examination is usually brief and lasts from a few to several minutes, depending on the specific type of scan.
For what purpose is a chest CT scan performed?
Chest CT is used for a variety of diagnostic and therapeutic purposes:
Diagnosis of lung diseases: chest CT is often used to diagnose various lung diseases, such as tumors, pneumonia, tuberculosis, COPD and fibrosis.
Monitoring disease and assessing response to treatment: CT can be used to monitor the progression of a disease, such as lung cancer, and to assess the body's response to treatment.
Surgery planning: Before surgery on the lungs, heart, or any other organ in the chest, CT can help doctors plan the procedure by providing detailed images of the patient's anatomy.
