Lev-Cohain N, Sosna J, Meir Y, et al. - This study was undertaken to investigate the potential role of low monoenergetic images in the evaluation of acute appendicitis. Researchers conducted a retrospective study including a total of 42 patients with pathology-proven acute appendicitis who had undergone contrast-enhanced-CT conducted on a single-source-dual-energy CT before surgery. They computed attenuation, SNR (signal-to-noise-ratio), and CNR (contrast-to-noise-ratio) on both monoenergetic and conventional images and compared to 24 abdominal CT-scans with a normal appendix. The data indicate that when assessing acutelly inflamed appendixes, elevated bowel wall conspicuity from enhanced attenuation, SNR, and CNR on low monenergetic CT images results in a significant preference by radiologists for these images. It has been considered that close inspection of low monoenergetic images may improve the visualization of acute inflammatory bowel processes.
