Trans‐Fistula Contrast‐Enhanced Ultrasound in Diagnosing a Complex Anal‐Bartholin‐Perineal Fistula of Crohn's Disease: A Case Report

open access: yesJournal of Clinical Ultrasound, EarlyView.
This case illustrates the potential utility of TF‐CEUS as a valuable adjunct in diagnosing complex fistulae. When MRI demonstrates limited sensitivity in detecting complex fistulae, TF‐CEUS can be chosen as a complementary imaging modality. It allows for real‐time, dynamic monitoring of the fistula branches, providing favorable conditions for early ...

Evaluating the Diagnostic Utility of Spinal Ultrasound in Neonates With a Simple Sacral Dimple: An Eight‐Year Retrospective Study

open access: yesJournal of Medical Radiation Sciences, EarlyView.
This study retrospectively analysed eight years of neonatal spinal ultrasound data from a major Australian children's hospital to assess the value of imaging for simple sacral dimples. Out of 448 scans, 195 were for an isolated simple dimple, and only two infants (1%) were found to have spinal dysraphism, both with other congenital anomalies.

A Multimodal Ultrasound Approach Combining Transperineal and Transrectal Shear Wave Elastography for Early Prediction of Stress Urinary Incontinence in Women

open access: yesJournal of Ultrasound in Medicine, EarlyView.
Objectives This study aims to evaluate the diagnostic value of a novel multimodal approach combining transperineal ultrasound (TPUS), transrectal dual‐plane ultrasound, and shear wave elastography (SWE) in predicting stress urinary incontinence (SUI). Methods A total of 70 women diagnosed with SUI and 110 healthy controls were included.
