Transcranial Color‐Coded Duplex Sonography in Large‐Vessel Vasculitis Compatible With Takayasu Arteritis Presenting Intracranial Involvement and Vertebrobasilar Dolichoectasia: A Case Report

open access: yesJournal of Clinical Ultrasound, EarlyView.
This case illustrates sequential intracranial occlusions in large‐vessel vasculitis compatible with Takayasu arteritis preserving perfusion through robust collateral pathways. Transcranial color‐coded duplex sonography identified characteristic blunted flow patterns and focal turbulence, underscoring its value in detecting hemodynamic compromise beyond

Active Control of Liner Impedance by Varying Perforate Orifice Geometry

open access: yes, 2000
The present work explored the feasibility of controlling the acoustic impedance of a resonant type acoustic liner. This was accomplished by translating one perforate over another of the same porosity creating a totally new perforate that had an ...

Percutaneous Closure of Patent Foramen Ovale in a Patient With Incomplete Cor Triatriatum Sinister: A Case Report

open access: yesJournal of Clinical Ultrasound, EarlyView.
We present the case of a 55‐year‐old male who experienced a cryptogenic ischemic stroke, likely due to a patent foramen ovale (PFO) in the setting of an incomplete cor triatriatum sinister (CTS) and a 30 mm GORE Cardioform Septal Occluder was successfully implanted.

Complicated Acute Appendicitis Conservatively Treated in Two Patients With Crohn's Disease: The Role of Intestinal Ultrasound and Contrast‐Enhanced Ultrasound

open access: yesJournal of Clinical Ultrasound, EarlyView.
Intestinal ultrasound and contrast‐enhanced ultrasound were used to diagnose, monitor, and guide conservative treatment of complicated acute appendicitis in two patients with Crohn's disease. Serial imaging enabled early identification of treatment response, allowing long‐term surgery‐free outcomes.

Effect of Visualized Respiratory Training on Patient Cooperation and Image Quality in Gadoxetic Acid Disodium‐Enhanced Liver MRI: A Randomized Controlled Trial

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Respiratory motion artifacts impair diagnostic accuracy in gadoxetic acid disodium (Gd‐EOB‐DTPA)‐enhanced liver MRI. Conventional verbal pre‐scan breathing training often yields inconsistent patient cooperation and image quality, creating an urgent clinical need for optimized training methods.
