Cat full form in medical

any method that produces images of single tissue planes. In conventional radiology, tomographic images (body section radiographs) are produced by motion of the x-ray tube and film or by motion of the patient that blurs the image except in a single plane. In reconstruction tomography (CT and PET) the image is produced by a computer program. computed tomography (CT) ( computerized axial tomography (CAT)) a radiologic imaging modality that uses computer processing to generate an image ( scan) of the tissue density in a “slice” as thin as 1 to 10 mm in thickness through the patient's body. These images are spaced at intervals of 0.5 to 1 cm. Cross-sectional anatomy can be reconstructed in several planes without exposing the patient to additional radiation. Since its introduction in 1972, the use of this modality has grown rapidly. Because it is noninvasive and has high contrast resolution, it has replaced some radiographic procedures using contrast media. It also has a better spatial resolution than scintillation imaging (about 1 mm for CAT compared to 15 mm for a scintillation camera). A CAT scan is divided into a square matrix of pixels (picture elements). The newer CAT scanners use a high resolution matrix with 256 × 256 or 512 × 512 pixels. The region of the tissue slice corresponding to a pixel has a cross-sectional area of 1 × 1 mm to 2 × 2 mm; because of the thickness of the slice, it has a finite height and is therefore referred to as a voxel (volume element). The actu...

Acronym What does CAT mean? Computerized Axial Tomography ( CAT) or CT scan, is an x-ray procedure that combines x-ray images taken from different angles with the aid of a computer to generate cross-sectional (tomographic) images of specific areas of a scanned object and, if needed, three-dimensional images of the internal organs and structures of the body.

Positron emission tomography During a positron emission tomography (PET) scan, you lie on a narrow table that slides into a doughnut-shaped hole. The scanner takes about 30 minutes to produce detailed images of metabolic activity in your tissues and organs. A positron emission tomography (PET) scan is an imaging test that can help reveal the metabolic or biochemical function of your tissues and organs. The PET scan uses a radioactive drug called a tracer to show both typical and atypical metabolic activity. A PET scan can often detect the atypical metabolism of the tracer in diseases before the disease shows up on other imaging tests, such as computerized tomography (CT) and magnetic resonance imaging (MRI). The tracer is most often injected into a vein within your hand or arm. The tracer will then collect into areas of your body that have higher levels of metabolic or biochemical activity. This often pinpoints the location of the disease. The PET images are typically combined with CT or MRI and are called PET-CT or PET-MRI scans. PET plus CT Combining a PET scan with an MRI or CT scan can help make the images easier to interpret. At left is a CT scan, while the center image is a PET scan. The image on the right is a combined PET-CT scan. The bright spot in the chest, seen best on the PET and PET-CT scans, is lung cancer. Cancer cells show up as bright spots on PET scans because they have a higher metabolic rate than do typical cells. PET scans may be useful in: • Detectin...
