CT patient positioning plays key role in radiation dose reduction
Technologists play a vital role in the reduction of radiation dose and image noise during CT scanning. One of the most effective techniques for reducing dose is patient positioning. Representatives of dose monitoring firm Qaelum provide an overview.

CT reveals changes in lung holes in emphysema patients
By Will Morton
CT imaging of lung holes could offer a new way to visualize and quantify the natural course of emphysema.
July 15, 2025
Emphysema progression with hole changes, with holes colored according to their diameter in 2-mm increments. (A) Baseline inspiratory nonenhanced axial CT scans in a 48-year-old man with chronic obstructive pulmonary disease show emphysema holes with hyperexpansion of secondary pulmonary lobules (white arrows) and thin alveolar walls visible in the right upper lobe. This emphysematous lesion is filled with holes of varying sizes. A single large air cyst was observed in the left upper lobe (black arrows), classified as a single emphysema hole of 20 mm or greater (bright green). (B) At six-year follow-up inspiratory nonenhanced axial CT, the holes in the right upper lobe have merged (white arrows), with no visible alveolar septa remaining, resulting in the formation of a large new hole of 20 mm or greater (bright green). Meanwhile, the hole in the left upper lobe also enlarged, merging with adjacent holes (black arrows). The size of other holes in the paramedian left upper lobe decreased.
