Takayanagi T, et al. - In this investigation, researchers ascertained if, in the evaluation of unconscious patients in the emergency department, a new-generation CT scanner that acquires images in ultrafast scan mode (large coverage, fast rotation, high helical pitch) would decrease motion artifacts on whole-body CT images in comparison with those on images obtained with a conventional CT scanner. They retrospectively evaluated images of a total of 60 unconscious patients presenting to the emergency department. In the assessment of unconscious patients, CT images acquired in the ultrafast scan mode had a significant reduction in motion artifacts. The ultrafast technique in the emergency department is anticipated to be helpful for diagnosing CT.
