What is a CT scan?

A CT scan uses x-rays to take pictures of your skull and brain. The patient lies in a tunnel-like machine. The inside of the machine rotates and takes x-rays of the head from different angles, which are later used by computers to make an image of a slice (or cross-section) of the brain. Why do doctors use CT scans? CT scans use computers and rotating x-ray machines to create images of slices, or cross-sections, of the brain. Unlike other techniques, CT scans (and MRI scans) can show the inside of the head, including soft tissue, bones, brains and blood vessels. CT scans can often show the size and locations of brain abnormalities caused by tumors, blood vessel defects, blood clots, and other problems. CT scans are a primary method of determining whether a stroke is ischemic or hemorrhagic (see the About Stroke section). Does a CT scan always diagnose a stroke? No. Even if you are having a stroke, it might not be seen on CT scan for several reasons. In many cases, the involved area of ...  more

(A)A CT Scan, sometimes called a CAT scan, is performed using special x-ray equipment to obtain image data from different angles around the body and then uses computer processing of the information to show a cross-section of body tissues and organs. CT imaging is particularly useful because it can show, with great clarity, several types of tissues including lung, bone, soft tissue, and blood vessels. Using specialized equipment and expertise to create and interpret CT scans of the body, radiologists can more easily diagnose problems such as cancers, cardiovascular disease, infectious disease, trauma and musculoskeletal disorders.  more

A CAT scan or a CT scan is a form of x-ray imaging that produces cross-sectional images of the body. The scanner itself is a short, open chamber with no enclosed tunnel. It does NOT interfere with metal stents or electronic devices such as pacemakers. CT scanners use computers to record the amount of x-ray beams passing through the body. By creating a series of CT images (slices) down the body, the radiologist can look at each image and get an accurate indication of position, size, and density of objects within the body. Virtual colonoscopy takes all of the slices and recreates them into a 3D image of your colon that can be rotated and looked at from various directions.

CT scan is short for Computed Tomography. It is an X–ray based equipment. The ‘CT scan’ is a technique that uses X–rays to take many multiple “Cross–section” images of the body, which are then assembled into a three–dimensional image by a computer. It is a painless non–invasive radiological investigation.  more

Dental CT Scans use advanced computer programs to analyse an X-ray study. By providing detailed two-dimensional and three-dimensional images, Dental CT Scans enable your dentist to select the best location for your implants and plan the details of your surgery with pinpoint accuracy, well before the operation.  more

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.  more

CT scanning — sometimes called CAT scanning — is a noninvasive, painless medical test that helps physicians diagnose and treat various medical conditions. It provides greater clarity than a regular x-ray exam. CT uses special x-ray equipment to produce multiple cross-sectional images or pictures of the inside of your body. The images can be seen on a computer or printed on film or paper.  more

A CT Scan (aka Cat Scan, CT imaging and Computed Tomography) is a procedure in which a 3 dimensional image is constructed from a series of radiologic "slices" of a particular region of the body. Images from a CT Scan are 1,000 times sharper than a regular x-ray and can pin-point lesions measuring less than 2mm.

CT is an abbreviation for computed tomography, an advanced type of x-ray study which uses x-rays to show cross-sections of body tissues and organs. This type of study is also referred to as a CAT scan (computed axial tomography). CT of the body is a patient-friendly exam that involves little radiation exposure. CT imaging is particularly useful because it allows visualization inside the body with amazing clarity. Using specialized equipment and expertise to create and interpret CT scans of the body, radiologists can more easily diagnose problems such as infectious disease, trauma, tumors, and musculo-skeletal disorders).  more

A CT scanner is a special x-ray machine combined with a computer that produces cross-sectional images or "slices" of any part of your head or body. Unlike a standard "flat" x-ray image where some structures block others, a CT scan shows structures within each slice on a three-dimensional plane. As a result, the doctor who views a CT scan can see your entire anatomy. The CT scan machine is open around you, does not touch you and is not confining. It should not be confused with an MRI scanner that is more of a tunnel-type structure. Even patients who suffer with claustrophobia find CT scans to be fairly simple, fast and easy.
