What is the primary purpose of a computed tomography (CT) scan?

The primary purpose of a computed tomography (CT) scan is to produce detailed images of internal structures in the body for diagnostic purposes. CT scans utilize X-rays to capture multiple cross-sectional images or slices of the body, which are then processed by a computer to create comprehensive two-dimensional and three-dimensional representations of organs, tissues, and other structures. This high level of detail allows healthcare providers to better visualize problems such as tumors, internal injuries, infections, and other abnormalities that might not be as clearly defined on standard X-rays.

While generating 3D models of bones for surgical planning and analyzing blood flow can be aspects of CT technology or related imaging studies, these are not the primary objectives of a typical CT scan. Additionally, CT scans do not entirely replace the need for traditional X-rays; rather, they complement other imaging modalities by providing more specific information in certain cases. Thus, the primary focus remains on diagnostic imaging to aid in patient assessment and treatment decisions.
