Computed tomography (CT)

Definition

Computed tomography (CT) is an imaging procedure that uses X-rays to create detailed cross-sectional images of the body. It helps in diagnosing and monitoring various medical conditions, including those affecting the pulmonary system.

5 Must Know Facts For Your Next Test

1. CT scans can detect abnormalities in the lungs such as tumors, infections, and chronic lung diseases.
2. The high-resolution images from CT scans provide more detail than standard X-rays, making them valuable for assessing complex pulmonary conditions.
3. Contrast agents are sometimes used during a CT scan to enhance the visibility of blood vessels and tissues in the lungs.
4. CT scans are non-invasive but expose patients to a higher level of radiation compared to regular X-rays; thus, their use is carefully considered based on clinical necessity.
5. Nutritional status can impact recovery outcomes post-CT scan procedures, especially in patients with compromised pulmonary function.
