AI Article Synopsis
- The study focuses on evaluating the performance of display systems in a large hospital, using criteria set by the American Association of Physicists in Medicine (AAPM) for primary and secondary displays.
- A telescopic photometer was utilized to measure luminance and contrast ratios under different lighting conditions, revealing that only about half of the displays met the AAPM's minimum standards in low light, while none met the criteria in ambient light.
- The article also addresses the challenges faced in enhancing display performance and calibration.
Article Abstract
This work describes our experience in reviewing the performance criteria for display systems and how we have implemented a practical approach to the assessment of the workstation environment in a large tertiary care hospital. The acceptance criteria contained in the draft report of Topic Group 18 of the American Association of Physicists in Medicine (AAPM) were used as a basis for assessment of primary and secondary displays. A telescopic photometer was used to measure the maximum luminance and the contrast ratio of the image for the displays used in our radiology department and in the operating and emergency rooms using the standard Society of Motion Picture and Television Engineers (SMPTE) pattern, in ambient light and with light decreased as much as possible. About half of the displays met the AAPM criteria for minimum luminance and contrast ratio in low light. None of the systems met the contrast ratio criteria in ambient light. The challenges in improving the performance and calibrating displays are discussed.

Department of Radiology, Yongchuan Hospital of Chongqing Medical University, Chongqing, China.
Objectives: To develop and validate the performance of CT-based radiomics models for predicting the prognosis of acute pancreatitis.
Methods: All 344 patients (51 ± 15 years, 171 men) in a first episode of acute pancreatitis (AP) were retrospectively enrolled and randomly divided into training (n = 206), validation (n = 69), and test (n = 69) sets with the ratio of 6:2:2. The patients were dichotomized into good and poor prognosis subgroups based on follow-up CT and clinical data.

Cognitive Neuroscience Centre, University of San Andres, Victoria, Buenos Aires, Argentina.
Background: Dementia impacts the way individuals perceive and describe everyday events. Alzheimer's disease (AD) notably affects processing of entities manifested by nouns, while behavioral variant frontotemporal dementia (bvFTD) often presents a detached, third-person perspective. Yet, the potential of natural language processing tools (NLP) to detect these variations in spontaneous speech remains explored.

Washington University School of Medicine in St. Louis, St. Louis, MO, USA.
Background: The 18F-AV-1451 radioligand enables in-vivo identification of tau neurofibrillary tangles that are considered as biomarkers of neurodegeneration in Alzheimer Disease (AD). However, off-target radioligand binding is also observed in basal ganglia, known as an iron-rich region. Hence, it is important to distinguish between radioligand-identified tissue neurodegeneration and iron-related radioligand binding effects.
