Objectives: Photon-counting detector CT (PCD-CT) is expected to substantially improve and expand CT-imaging applicability due to its intrinsic spectral capabilities, increased spatial resolution, reduced electronic noise, and improved image contrast. The current study aim is to evaluate PCD-CT efficacy in characterizing bullets based on their dimensions, shape, and material composition.

Materials And Methods: This is an observational phantom study examining 11 unfired, intact bullets of various common calibers, placed in ballistic gelatin.

Article Synopsis
  • Social cognition is crucial for interpreting social information, and this study examined its impairment in individuals with Korsakoff's syndrome (KS) and alcohol-related dementia (ARD) compared to healthy controls.
  • The study included 30 KS patients, 10 ARD patients, and 74 matched controls, using the Social Norms Questionnaire to measure social cognition.
  • Results indicated that both KS and ARD patients struggled more with judging social norms than controls, with KS patients making significantly more judgment errors, highlighting the social behavior challenges faced by these patients.

Background: Both CT angiography and CT perfusion involve the administration and tracking of a contrast medium bolus for different purposes. In this study, we aim to compare the diagnostic accuracy and subjective image quality of CTP-angiographic reconstructions with conventional CTA for occlusion detection in ischemic stroke patients.

Methods: In this retrospective study, patients with a final diagnosis of ischemic stroke and who underwent both CTA and CTP from September 2020 up to and including September 2021 were included.
