Study of Risk Factors and Image Findings of Isolated Abdominal Incidentally Detected Aortic Dissection

open access: yesJournal of Clinical Ultrasound, Volume 53, Issue 3, Page 429-435, March/April 2025.
We detect the risk factors and image characteristics of incidentally detected IAAD. Independent risk factors of IAAD included fatty liver and smoking. In the ultrasound findings of IAAD, an intimal flap was frequently observed. In the CT scan, displacement of intimal calcifications was frequently observed. For suspected IAAD, the abdominal aorta should

Contrast Kinetics in CT Coronary Angiography

open access: yesIndian Journal of Radiology and Imaging
Computed tomography coronary angiography (CTCA) is a technically demanding radiological investigation that requires adequate opacification of coronary arteries at peak aortic enhancement phase, with minimal or no contrast in the superior vena cava and ...

Old disease, new twist

open access: yesJournal of Hospital Medicine, EarlyView.
Abstract An 81‐year‐old man with a history of high‐grade urothelial carcinoma of the bladder and ureter on treatment with atezolizumab and tiragolumab presented to the emergency department with 5 months of malaise, generalized weakness, and fatigue and 2 weeks of subjective fevers. One month prior to presentation, he received an empiric 9‐day course of

Agentic Artificial Intelligence in Medical Imaging Education: Architectural Autonomy and the Risk of Cognitive Surrender

open access: yesJournal of Medical Radiation Sciences, EarlyView.
Agentic AI systems embedded within imaging workflows may alter reflective reasoning by reshaping when and how verification occurs. This Perspective proposes a Tri‐System framework and argues for educational recalibration to preserve diagnostic complementarity, calibrated trust, and accountable human supervision within architecturally integrated ...

Mapping the Landscape of Over‐Scanning in CT Imaging: A Scoping Review

open access: yesJournal of Medical Radiation Sciences, EarlyView.
Over‐scanning in CT is highly prevalent and contributes to unnecessary radiation exposure, with notable impact on radiosensitive organs. Standardised protocols and AI‐assisted planning show strong potential to optimise scan range and reduce excess dose.
