Feasibility and perceptions among hemophilia patients and doctors towards ultrasound for the assessment of subclinical abnormalities in hemophilic joints

This study explores the feasibility and perceptions of using ultrasound (US) for identifying subclinical abnormalities in hemophilic joints from the perspectives of both patients and medical practitioners. This was a single-center pilot follow-up study that included multidiscipli...

Establishing CT-number-to-electron/density curves for hypersight CBCT with a standard cirs 062 M phantom: a methodological comparison of three practical approaches

HyperSight cone-beam computed tomography (CBCT) with Acuros reconstruction is reported to enable direct dose calculation in adaptive radiotherapy, but its accuracy depends on a reliable CT-number-to-electron/material-density (CT-ED/MD) calibration curve.The CT-number-to-material-...

Apparent Intramyocellular Lipid Index Using Spiral Magnetic Resonance Spectroscopic Imaging at 3 T

Abstract Purpose: This work introduces a rapid, high-resolution method based on spiral Magnetic Resonance Spectroscopy Imaging (MRSI) to map the apparent content of intramyocellular (IMCL) and extramyocellular (EMCL) lipids in human skeletal muscle. Methods: Unsuppressed water sp...

Evaluation of clinical performance of artificial intelligence-assisted measurement of thoracic aortic diameter on non-contrast CT

This study aimed to evaluate the clinical performance of artificial intelligence (AI)-assisted measurement of thoracic aortic diameter on non-contrast computed tomography (NCCT). This single-center prospective study included 79 patients (mean age = 70 ± 13 standard deviation; 46...

Mobile cone-beam computed tomography combined with electromagnetic navigation bronchoscopy for the diagnosis of peripheral pulmonary nodules

BACKGROUND: Electromagnetic navigation bronchoscopy (ENB) is widely used for diagnosing peripheral pulmonary nodules (PPNs), but its diagnostic yield remains variable. Mobile cone-beam computed tomography (mCBCT) enables intraprocedural assessment of the tool-lesion relationship...

Design for Human Variability: Reflections from the HFES Council of Affinity Groups (COAG)

The Human Factors and Ergonomics Society (HFES) is dedicated to recognizing human variability and understanding how it shapes interactions between people and systems. Building on previous panels, this discussion panel examines human variability through the lens of HFES Affinity G...

Flame Structures and Emissions of Premixed Partially Cracked Ammonia/Air Swirl Flames

Waste-heat-assisted catalytic cracking offers a practical route to improve the reactivity of ammonia for gas turbine applications. This study experimentally examines the effects of cracking ratio on flame structure, stability, and nitrogen oxide emissions in a model gas turbine c...

Repetitive transcranial magnetic stimulation normalizes cerebrocerebellar loop functional connectivity in spinocerebellar ataxia type 3

Abstract Background Spinocerebellar ataxia type 3 (SCA3) is a rare neurodegenerative disorder characterized by ataxia; structural and functional damage to the cerebrocerebellar loop play key roles in its pathology. However, effective treatments for SCA3 remain limited. Repetitive...
