CT (CAT) scanning—is a noninvasive medical test that helps physicians diagnose and treat medical conditions.- combines special x-ray equipment with sophisticated computers to produce multiple images or pictures of the inside of the body.-. These cross-sectional images of the area being studied can then be examined on a. Ct scan 1. 2D imaging was used - X-rays there was super imposition of structures. less clarity of images 2. Computed : use of computer Tomography: Greek word tomos means slice, graphy means write. Computed Tomography is the process of generating a two-dimensional image of a slice or section through a 3-dimensional object (a tomogram. MedCross Imaging - CT OR CAT SCAN - Computed tomography - more commonly referred to as CT, CT scan or CAT scan - uses x-rays and advanced computer technology to generate detailed cross-sectional, and if needed, three-dimensional views of the body's internal organs and body structures. CT scans are used to identify normal and abnormal body. Computed Tomography (CT) was introduced into clinical. practice in 1972 and revolutionized X Ray imaging by. providing high quality images which reproduced transverse. cross sections of the body. Tissues are not superimposed on the image as they are in. conventional projections

CT SCAN vs MRI SCAN A CT 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 Radiology PowerPoint Tip • Xray of the Week • Week #49 Have you ever wondered how to get a scrollable image stack of CT or MR images on a single PowerPoint slide.

This helps highlight certain areas, like the stomach, bowels. Splenic injury. The spleen is the most frequently injured abdominal organ during blunt abdominal trauma and accounts for up to 45% of all visceral injuries ().A CT scan following the power injection of intravenous contrast is highly accurate (98%) in diagnosing acute splenic injuries ().CT scans can detect a variety of splenic injuries, including laceration, a non-perfused region, intra. Several imaging modalities have been used in the evaluation of suspected osteomyelitis, but no one can definitively confirm the presence or absence of infection. 13 Cross-sectional imaging modalities such as computed tomography (CT) scanning and magnetic resonance imaging (MRI) are now considered standard in the diagnosis of osteomyelitis. Numerous imaging modalities may be used for the staging of women with advanced breast cancer. Although bone scintigraphy and multiplanar-CT are the most frequently used tests, others including PET, MRI and hybrid scans are also utilised, with no specific recommendations of which test should be preferentially used. We review the evidence behind the imaging modalities that characterise.

Computed tomography (CT scan or CAT scan) is a noninvasive diagnostic imaging procedure that uses a combination of X-rays and computer technology to produce horizontal, or axial, images (often called slices) of the body. A CT scan shows detailed images of any part of the body, including the bones, muscles, fat, organs, and blood vessels All computed tomography (CT) scans use x-rays to quickly create cross-sectional pictures of your body. A dual-source CT scan uses two x-ray sources at right angles to each other. This doubles the speed of the test so you receive less radiation, and it also creates sharper images. A dual-source CT scan can be used to guide a surgeon to the right.

Positron emission tomography, also called PET imaging or a PET scan, is a diagnostic examination that involves getting images of the body based on the detection of radiation from the emission of positrons. Positrons are tiny particles emitted from a radioactive substance administered to the patient. Patient Safety Tips Prior to the Exam Please let us know if you have any allergies or adverse. Computed tomography, more commonly known as a CT or CAT scan, is a diagnostic medical imaging test. Like traditional x-rays, it produces multiple images or pictures of the inside of the body. The cross-sectional images generated during a CT scan can be reformatted in multiple planes Computed tomography (CT) is readily accessible and images can be acquired quickly, reducing the need for sedation that may be required for MRI. However, CT should be used judiciously in children because it has the disadvantage of exposing patients to ionizing radiation. When performing CT scans in children, the ALARA principle should always apply The increasing use of imaging in the population will inevitably result in an increase in requests for imaging in women who are pregnant or lactating.
