High‐Frequency Ultrasonographic Characterization of Subcutaneous Glomus Tumors

Journal of Clinical Ultrasound, EarlyView.
Color Doppler image reveals intralesional hypervascularity. ABSTRACT Objective To evaluate the clinical manifestations and ultrasonographic characteristics of glomus tumors under the nails and other subcutaneous soft tissues. Methods A retrospective analysis was performed on 45 patients with pathologically confirmed glomus tumors who underwent ...

The Application Value of Transvaginal Three‐Dimensional Ultrasonography in the Diagnosis of Adenomyosis of the Uterus

Journal of Clinical Ultrasound, EarlyView.
In this study, 3D‐TVS measurements of the uterine junction zone (JZ) in 120 patients showed that a JZmax threshold of ≥ 0.45 cm yielded 77% sensitivity and 89% specificity for adenomyosis diagnosis. Notably, JZ thickness varies minimally with age, demonstrating its stability and excellent diagnostic performance.

Motion Mitigation Techniques for Abdominal and Cardiac MR Imaging

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT MRI of the heart and abdominal organs provides unparalleled soft tissue contrast and quantitative biomarkers, yet remains highly susceptible to physiological motion. Contractions of the myocardium, respiratory excursions, peristalsis, vascular pulsatility, and unpredictable bulk patient movement generate artifacts that impair image quality ...

Pre‐operative transcranial Doppler ultrasound assessment of cerebral collateral circulation in children undergoing veno‐arterial extracorporeal membrane oxygenation or cardiac surgery

Journal of Medical Radiation Sciences, EarlyView.
A pre‐cannulation survey of the circle of Willis (CoW) using transcranial Doppler (TCD) ultrasound was implemented to assess cerebral collateral circulation in children undergoing VA ECMO or cardiac surgery with cervical cannulation. The technique, in use since 2019, employs high‐end ultrasound platforms to assess brain morphology, haemorrhage and ...

Surrogate measure of gut blood flow via superior mesenteric circulation on ultrasound in adults who underwent esophagectomy: A descriptive cohort study

Journal of Parenteral and Enteral Nutrition, EarlyView.
Abstract Background Early enteral nutrition is recommended for critically ill patients. However, feeding an ischemic gastrointestinal tract with enteral nutrition may lead to gut necrosis. Although gut tolerance of enteral nutrition is assessed by various symptoms, none of them provide conclusive evidence of gut ischemia. We investigated the blood flow

Reshaping study design for faster extrapolation‐based drug approval in pediatric inflammatory bowel diseases: An ESPGHAN–NASPGHAN position paper

Journal of Pediatric Gastroenterology and Nutrition, EarlyView.
Abstract Children with inflammatory bowel diseases (IBD) have limited access to the available advanced therapies, given the lengthy gap between adult and pediatric approval. We aimed to review key hurdles for pediatric trials and recommend practical solutions.

Temperature‐Dependent Investigation of the S‐Branch Raman Linewidth in CO2 via Time‐Resolved Rotational CARS

Journal of Raman Spectroscopy, EarlyView.
We studied the temporal evolution of the rotational coherent anti‐Stokes Raman scattering (RCARS) signal of CO2 to determine the S‐branch Raman linewidth, which is an essential parameter for accurate spectral modeling in RCARS gas‐phase diagnostics. We found a non‐monotonic J‐dependence of the S‐branch Raman linewidth not accounted for in previously ...
