Sex differences in inappropriate imaging requests: insights from the Medical Imaging Decision And Support (MIDAS) study

Stijntje Willemijn Dijk, Claudia Wollny, Thomas J. Kröncke, M. G. Myriam Hunink

OBJECTIVE: Inappropriate diagnostic imaging can lead to unnecessary radiation exposure, delayed diagnoses, and increased healthcare costs. While multiple factors contribute to inappropriate imaging, sex-based disparities remain understudied. This study investigates whether inappropriate imaging requests differ among women and men. MATERIALS AND METHODS: …

Challenges and insights from implementing clinical decision support systems for radiologic imaging: experience from the MIDAS trial

Thomas J. Kröncke, Stijntje Willemijn Dijk, Moritz C. Halfmann, Claudia Wollny et autres

Clinical decision support systems (CDSSs) have been developed to give guidance for referring physicians to make appropriate decisions at the point of care. The MIDAS study, a multicenter cluster randomized trial at four German university hospitals, was designed to evaluate the effectiveness …

Prognostic value of CT-defined coronary sclerosis in COVID-19: results of a multicenter study based on the Weston score

Andreas Michael Bucher, Eric Frodl, Constantin Ehrengut, Lukáš Müller et autres

Coronary calcification, as defined by computed tomography (CT), can be quantified with a score (CAC score). It is an established prognostic and predictive imaging marker of the cardiovascular risk profile. The prognostic relevance of the CAC score has been demonstrated for acute …
