Computed Tomography (CT or CAT) Scan of the Chest 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. In a CT scan, an X-ray beam moves in a circle around your body. It takes many images, called slices, of the lungs and inside the chest. A computer processes these images and displays it on a monitor. During the test, you may receive a contrast dye.

- 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.

Diagnosing neck or back pain with a CT scan Sections. A computed tomography scan (also known as a CT scan or CAT scan) uses X-rays and computer processing to create three-dimensional views of the inside of the body. Unlike regular X-ray images, CT scans use X-rays taken from various angles to create a “cross-section” view of the spine and other bony structures.

What to Expect During a CT Scan The medical term, Computed Tomography scan, is the long version for a CT scan, a special type of x-ray which is also sometimes referred to as a CAT scan. The images produced by a CT scan are very detailed cross-sectional pictures of the body that allow for a look at tissues and organs inside the body. It can help diagnose conditions such as: 1  broken bones.  tumors.

Contents: CT Scan vs MRI CT Scan vs. MRI. 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. An MRI, on the other hand, can take up to 30 minutes. An MRI typically costs more than a CT scan.

Lyme Disease Neuropathy Lyme disease is an inflammatory disease that rapidly progresses. Transmitted by the bite of an infected deer tick, Lyme disease is most common in the Northeast section of the United States. However, the disease has also appeared in the upper East coast, in the upper Midwest, and along the coasts of northern California and Oregon.

MetLife agrees to multistate settlement over death benefit claims April 24, 2012 | By Tiffany Hsu, Los Angeles Times. Life insurance giant MetLife Inc. will shell out roughly $500 million in a multistate settlement of its alleged failure to pay death benefits to heirs, regulators said.he funds will either be sent on to beneficiaries of deceased MetLife policyholders or stored in state coffers as unclaimed property. More than 30,000 California-based MetLife policies are affected, each with an average cash value of $1,200, Chiang said in a statement.

About This Procedure CTA is a type of exam that uses CT technology to look at blood vessels. A CT scanner rotates to take X-ray images from different angles all around your body. A computer puts these images together to form detailed, two-dimensional pictures. CT provides clearer, more detailed pictures than traditional X-rays.

Diagnosing Heart Disease With Cardiac Computed Tomography (CT) Computed tomography, commonly known as a CT scan, combines multiple X-ray images with the aid of a computer to produce cross-sectional views of the body. Cardiac CT is a heart-imaging test that uses CT technology with or without intravenous (IV) contrast (dye) to visualize the heart anatomy, coronary circulation, and great vessels (which includes the aorta, pulmonary veins, and arteries).

Medical Imaging CT stands for Computed Tomography. It is a computerized X-ray machine that examines the body. The scanner is comprised of a table and a gantry. The gantry is the donut shape part that houses the X-ray source. The X-ray source rotates inside the gantry as the patient moves through. Data is obtained and processed by a computer to produce a two dimensional image.

What Is Diagnostic Imaging? A CT scan is a method of diagnostic imaging that produces an image of anatomy at different levels within the body. The ASRT notes that this procedure is also referred to as cross-sectional imaging. CT scans are used in particular situations, such as checking for internal bleeding, stroke, blood clots and tumors.iagnostic imaging is a process by which a magnetic image is taken of the human body to diagnose a particular problem the patient may be having.

CT Scan CT Scan. A CT or CAT scan is a diagnostic imaging procedure that uses a combination of x-rays and computer technology to produce cross-sectional images (often called slices), both horizontally and vertically, of the body. A CT scan shows detailed images of any part of the body, including the bones, muscles, fat, organs, and blood vessels.

Medical Dictionary A computed tomography (CT) scan uses X-rays to make pictures of the head and face. During the test, you will lie on a table that is attached to the CT scanner, which is a large doughnut-shaped machine. Your head will be positioned inside the scanner. The CT scanner sends X-rays through the head. Each rotation of the scanner provides a picture of a thin slice of the head and face.

Computed Tomography (CT) Scans and Cancer Computed tomography is an imaging procedure that uses special x-ray equipment to create detailed pictures, or scans, of areas inside the body. It is also called computerized tomography and computerized axial tomography (CAT). The term tomography comes from the Greek words tomos (a cut, a slice, or a section) and graphein (to write or record).

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.
