What is computed axial tomography?

Definition of computed tomography : radiography in which a three-dimensional image of a body structure is constructed by computer from a series of plane cross-sectional images made along an axis. — called also computed axial tomography, computerized axial tomography, computerized tomography.

Why are CT scans used?

CT scans can detect bone and joint problems, like complex bone fractures and tumors. If you have a condition like cancer, heart disease, emphysema, or liver masses, CT scans can spot it or help doctors see any changes. They show internal injuries and bleeding, such as those caused by a car accident.

What is the medical term for computerized tomography?

A CT scan may be used to help diagnose disease, plan treatment, or find out how well treatment is working. Also called CAT scan, computed tomography scan, computerized axial tomography scan, and computerized tomography.

What is CT scan for Covid?

Chest computed tomography (CT) scan is an important method for the diagnosis of COVID-19 pneumonia [5]. Being more time-saving and having a comparable sensitivity versus RT-PCR assay make CT scan a powerful tool for rapid screening of the suspected cases [6, 7].

What is a CT scan used for brain?

Computed tomography (CT) of the head uses special x-ray equipment to help assess head injuries, severe headaches, dizziness, and other symptoms of aneurysm, bleeding, stroke, and brain tumors. It also helps your doctor to evaluate your face, sinuses, and skull or to plan radiation therapy for brain cancer.

Whats a CT on a girl?

A computed tomography (CT) scan of the pelvis is an imaging method that uses x-rays to create cross-sectional pictures of the area between the hip bones. This part of the body is called the pelvic area.

Why do I need an MRI after a CT scan?

After a physician initially spots a tumor, cancer patients may undergo further testing to help their oncologist stage and monitor their cancer. Both MRI and CT are used to produce images of the area of the body where the tumor is located, which can aid an oncologist may use in determining the best treatment options.

What is a chest CAT scan?

What is a CT scan of the chest? CT scan is a type of imaging test. It uses X-ray and computer technology to make detailed pictures of the organs and structures inside your chest. These images are more detailed than regular X-rays. They can give more information about injuries or diseases of the chest organs.

What is CAT (computerized axial tomography)?

Computerized Axial Tomography (CAT) is the medical imaging method employing tomography created by computer processing. It is also known as computed tomography. In CT imaging X-rays are used in conjunction with computing algorithms to image the body. In computed tomography a volume of data is produced.

What is a computed tomography scan?

What is a computed tomography (CT) scan? The term “ computed tomography ”, or CT, refers to a computerized x-ray imaging procedure in which a narrow beam of x-rays is aimed at a patient and quickly rotated around the body, producing signals that are processed by the machine’s computer to generate cross-sectional images—or “slices”—of the body.

What is another name for tomography other than X-ray?

For means of tomography other than X-ray, see Tomography. A CT scan or computed tomography scan (formerly known as computed axial tomography or CAT scan) is a medical imaging technique used in radiology to get detailed images of the body noninvasively for diagnostic purposes.

What is a CAT scan used to diagnose?

A computed axial tomography (tuh-mah-gruh-fee) scan is also called a “CT” or “CAT” scan. It is a painless test that takes pictures of the inside of the body. CT scans are especially good for showing bone, soft tissue, and blood vessels.
