CT SCANNING Meaning and
Definition
-
CT scanning, also known as computed tomography scanning, is a medical diagnostic imaging technique that combines a series of X-ray images taken from different angles around the body to create detailed cross-sectional images. This noninvasive procedure provides highly detailed and accurate images of the body's internal structures, including bones, tissues, and organs.
During a CT scan, the patient lies on a movable examination table that slides into a large, donut-shaped machine called a CT scanner. The scanner emits a narrow beam of X-ray radiation that rotates around the body. Detectors in the scanner measure the amount of X-rays that penetrate through the body and create digital images. These images are reconstructed by a computer into cross-sectional slices, or "slices," which can be viewed from different angles.
CT scanning is widely used in various medical specialties to diagnose and monitor a wide range of conditions, including tumors, fractures, internal bleeding, infections, and vascular diseases. It is particularly useful in emergency departments due to its quick image acquisition and ability to identify injuries or internal bleeding rapidly.
Advancements in CT technology have enabled the development of more specialized scans, such as contrast-enhanced CT scans that involve the injection of a contrast dye to enhance the visibility of certain structures or organs. Additionally, CT angiography uses CT scanning to examine blood vessels, providing detailed images of the cardiovascular system.
Overall, CT scanning is a vital imaging technique that aids healthcare professionals in diagnosing and managing a broad spectrum of medical conditions through its ability to generate highly accurate and detailed images of the body.

Etymology of CT SCANNING
The word "CT scanning" is derived from "computed tomography scanning".
The term "computed" refers to the use of computers to process and analyze data, while "tomography" comes from the Greek words "tomos", meaning "slice", and "graphē", meaning "drawing" or "description".
When combined, "computed tomography" refers to the technology that uses computer processing to produce detailed cross-sectional images of the body. The term "scanning" is added to denote the action of obtaining these images by passing X-rays through the body.
