Computed Tomography (CT) 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.

Medical imaging A chest computed tomography (to-MOG-ra-fee) scan, or chest CT scan, is a painless, noninvasive test. It creates precise pictures of the structures in your chest, such as your lungs. Noninvasive means that no surgery is done and no instruments are inserted into your body. A chest CT scan is a type of x ray.However, a CT scan's pictures show more detail than pictures from a standard chest x ray. Like other x-ray tests, chest CT scans use a form of energy called ionizing radiation. This energy helps create pictures of the inside of your chest.octors use chest CT scans to: 1  Show the size, shape, and position of your lungs and other structures in your chest. 2  Follow up on abnormal findings from standard chest x rays. 3  Find the cause of lung symptoms, such as shortness of breath or chest pain.

Abdominal CT Scan Overview. A CT scan is a type of X-ray that can show cross-sectional images of a specific area of the body. The machine circles the body and sends the images to a computer, where they are viewed by a technician. Each picture is viewed as a cross-section of the body to provide doctors with alternate views of your body.

- A CT scan is a computerized axial tomographic scan. A CT scan uses special X-ray equipment to produce an image that is a cross section or a slice of your body.When you are looking at or “reading” a CT scan film, think of the patient like a loaf of bread and the image like one slice from that loaf.his link offers a good overview of CT scans, including information on how this scan is done. Pay special attention to the images presented by this link. The CT scan image of the abdomen offers a great comparison of a traditional X-ray and a CT scan.

CT scan A CT scan, also known as computed tomography scan, makes use of computer-processed combinations of many X-ray measurements taken from different angles to produce cross-sectional images of specific areas of a scanned object, allowing the user to see inside the object without cutting. Other terms include computed axial tomography and computer aided tomography. Digital geometry processing is used to further generate a three-dimensional volume of the inside of the object from a large series of two-d

Contents: CT Scan vs MRI CT Scan vs. MRI Diffen › Health › Diagnostics A CT Scan (or CAT Scan) is best suited for viewing bone injuries, diagnosing lung and chest problems, and detecting cancers. An MRI is suited for examining soft tissue in ligament and tendon injuries, spinal cord injuries, brain tumors, etc. CT scans are widely used in emergency rooms because the scan takes fewer than 5 minutes.

Frequently Asked Questions What is a CT scan? CT, which stands for Computed Tomography (sometimes referred to as a “CAT” scan), is a fast, painless diagnostic tool doctors can use to see inside the body. Physicians use the information they get from a CT scan to rule out or confirm the presence of certain abnormalities or diseases.

Computed tomography (CT) and CT angiography Computed tomography (CT) and CT angiography. Overview. A computed tomography (CT) scan is a noninvasive diagnostic test that uses x-rays and a computer to create images of the body. It allows your doctor to view your spine or brain in slices, as if it were sliced layer-by-layer and a picture taken of each slice.

Cardiac CT Scan Also known as computed tomography; computed axial tomography scan (CAT scan). A cardiac CT scan is a painless imaging test that uses x rays to take many detailed pictures of your heart and its blood vessels. Computers can combine these pictures to create a three-dimensional (3D) model of the whole heart.

Overview A computerized tomography (CT) scan combines a series of X-ray images taken from different angles and uses computer processing to create cross-sectional images, or slices, of the bones, blood vessels and soft tissues inside your body. CT scan images provide more detailed information than plain X-rays do. A CT scan has many uses, but is particularly well-suited to quickly examine people who may have internal injuries from car accidents or other types of trauma.

Basic principles of computed axial tomography Today, the term computed (axial) tomography (CT) most often refers to a new diagnostic radiological pro- cedure which provides images of transverse sec- tions of the body. As in other radiographic procedures, the CT image reflects variations in the attenuation of x-rays in the object imaged.
