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

Journal 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

Dynamic Ultrasound Imaging of Extensor Pollicis Brevis Hypertrophy in Proximal Intersection Syndrome: A Case Report and Literature Review

Journal of Clinical Ultrasound, EarlyView.
Dynamic ultrasound revealed extensor pollicis brevis hypertrophy displacing second compartment tendons, suggesting a novel friction‐based mechanism for proximal intersection syndrome. This case highlights the role of dynamic sonography in identifying motion‐dependent tendon interactions underlying overuse‐related wrist pain.

Ultrasound‐Based Z Score and Pulmonary Valve/Aortic Valve Diameter Ratio Improving the Predictive Value of Fetal Aortic Stenosis

Journal of Clinical Ultrasound, EarlyView.
A total of 24 singleton fetuses with suspected AS who underwent two or more fetal echocardiograms were enrolled in this study. Using electronic spatiotemporal image correlation (eSTIC) technology, the AV and PV Z scores, along with the PV/AV ratio, were measured and compared between two echocardiographic examinations to assess diagnostic efficacy ...
