This study gives a comprehensive overview of the subject, covering its background, modalities, number of CT scans, Hounsfield units, and scale in relation to specific applications. Currently, computed tomography (CT) has emerged as a groundbreaking technique in the field of medical imaging. In addition to being referred to as the Hounsfield unit, the numerical picture of a pixel is also known as the CT number. The viewpoint that lies behind the quality of the image and the reconstruction of the image in the form of grayscale. The abbreviation for this scale is the HU level. In recognition of Sir Godfrey Newbold Hounsfield, the scale was given the name "Hounsfield Unit." The value of the gray shade is represented by this scale according to the attenuation. Because it assists in determining the degree of radiation intensity decrease and, as a result, provides a specific numerical value in each pixel, attenuation plays a significant part in the process. Information on the HU value may be obtained by establishing a region of interest (ROI) on a specific slice or segment of an image. This information is helpful in determining the relevance of the HU value in terms of detection, assessment, therapy, and diagnosis. The return on investment (ROI), which is taken into consideration and utilized in post-processing approach, provides HU value immediately following its placement, which is not less than Artificial Intelligence (AI).
