Digital panoramic radiographs may be viewed with computer monitors or archived as thermal or laser prints. To compare the available diagnostic information from thermal print images to that of corresponding computer monitor images, four calibrated evaluators performed a qualitative analysis of 13 specified anatomic features in 60 pairs of digital panoramic images presented in random order on a computer monitor and as thermal printed images. Each anatomic site was rated both for subjective diagnostic quality and diagnostic utility using a nominal scale. Computer monitor images more often were subjectively judged to have better quality. Within the parameters of this study, both formats had acceptable diagnostic utility for the majority of the anatomic features evaluated.

CardiacField: computational echocardiography for automated heart function estimation using two-dimensional echocardiography probes.
Eur Heart J Digit Health
January 2025
Department of Cardiovascular Surgery of Zhongshan Hospital, Fudan University, Shanghai 200032, China.
Aims: Accurate heart function estimation is vital for detecting and monitoring cardiovascular diseases. While two-dimensional echocardiography (2DE) is widely accessible and used, it requires specialized training, is prone to inter-observer variability, and lacks comprehensive three-dimensional (3D) information. We introduce CardiacField, a computational echocardiography system using a 2DE probe for precise, automated left ventricular (LV) and right ventricular (RV) ejection fraction (EF) estimations, which is especially easy to use for non-cardiovascular healthcare practitioners.

Introduction: Severe or complicated atheromatosis of the aortic arch represents an important and often underdiagnosed embolic source in patients with ischemic stroke. The presence of a floating thrombus has significant clinical relevance, as it is associated with a high risk of early recurrence. The aim of this study was to analyze the potential of echocardiographic examination through the suprasternal window in both the detection of embolic sources and the monitoring of the response to anticoagulant treatment in patients with mobile thrombi.

Department of Community Nutrition, School of Nutritional Sciences and Dietetics, Tehran University of Medical Sciences, P. O. Box: 1416643931, Tehran, Iran.
Objectives: An efficient approach to monitor the risks associated with chronic diseases is to use a dietary diversity score (DDS). To our knowledge, there has been no study conducted on the correlation between DDS and cardiovascular risk factors in individuals with diabetes. Hence, the objective of this study is to ascertain the correlation between these traits.

Multiple sclerosis (MS) is an autoimmune disease of the brain and spinal cord with both inflammatory and neurodegenerative features. Although advances in imaging techniques, particularly magnetic resonance imaging (MRI), have improved the process of diagnosis, its cause is unknown, a cure remains elusive and the evidence base to guide treatment is lacking. Computational techniques like machine learning (ML) have started to be used to understand MS.
