CT, or computerized axial tomography (CAT) scans, are medical imaging tests that are used to take pictures of parts of the body at different angles to create detailed images of internal organs, blood vessels, and bones. The information gained by CT and MRI scans has been directly linked to greater life expectancy and declining cancer death rates. Computed tomography (CT) scanning is an extremely common imaging modality in modern medicine.With advancements in technology, it is rapidly replacing many diagnostic radiographic procedures. The data produced can be manipulated to demonstrate the different structures depending on their ability to absorb the beams. An X-ray is one of the fastest types of medical scans that can be performed. CT scans are typically more expensive than x-rays and aren’t always readily available at rural or small hospitals. A CT scan, also called a CAT scan, is a high powered type of X-ray technology that looks for internal bleeding, broken bones, blood clots, tumors, musculoskeletal diseases, arterial blockages, and heart disease.During this examination, the patient lies on a table and moved through a donut hole-like opening in the X-ray machine. CT scans can be used for diagnostic and therapeutic purposes. A CT scan is a diagnostic imaging exam that uses X-ray technology to produce images of the inside of the body. Types of PET Scans. Procedures. A Computed Tomography (CT) Scan uses X-rays and a sophisticated computer to view specific parts of the anatomy in great detail. CT scans are sometimes referred to as CAT scans or computed tomography scans. Like traditional x-rays, it produces multiple images or pictures of the inside of the body. Computer Tomography (CT) CT or ‘CAT’ scans are a form of X-ray that creates a 3D picture for diagnosis. This radioactive tracer is chosen based on which area of the body is under investigation. Contrast dye is usually injected into the body before the scan … Those who perform CT scans are either radiologic technologists or radiographers. This type of radiology study is an important part of diagnosing medical diseases like strokes, cancers, and infections in the abdomen like appendicitis.

The CT scanner has … Computed Tomography (CT), also known as Computerized Axial Tomography (CAT) scans, and Magnetic Resonance Imaging (MRI) scans are two of the most common types of diagnostic imaging. A CT scan is typically used for: bone fractures Computed tomography is an imaging procedure that uses special x-ray equipment to create detailed pictures, or scans, of areas inside the body. A CT scan or CAT scan is a type of medical imaging procedure that doctors may use to view bones, organs, and soft tissues inside a person’s body.. Certain types of brain scans use a special dye, called contrast, to help areas of interest show up better. Positron Emission Tomography (PET) CT Scan. Medical imaging is the technique and process of creating visual representations of the interior of a body for clinical analysis and medical intervention, as well as visual representation of the function of some organs or tissues ().Medical imaging seeks to reveal internal structures hidden by the skin and bones, as well as to diagnose and treat disease. The most common scans for diagnosis and follow-up are magnetic resonance imaging (MRI) and computerized tomography (CT). The term tomography comes from the Greek words tomos (a cut, a slice, or a section) and graphein (to write or record). CT scans are sometimes referred to as CAT scans or computed tomography scans. DICOM stands for Digital Imaging and Communications in Medicine. A CT/CAT scan can be performed on every area of the body and provides greater clarity than traditional X-rays.
