How to perform Contrast-Enhanced Ultrasound (CEUS)

"How to perform contrast-enhanced ultrasound (CEUS)" provides general advice on the use of ultrasound contrast agents (UCAs) for clinical decision-making and reviews technical parameters for optimal CEUS performance. CEUS techniques vary between centers, therefore, experts from EFSUMB, WFUMB and from the CEUS LI-RADS working group created a discussion forum to standardize the CEUS examination t...

Routine preoperative vascular ultrasound improves patency and use of arteriovenous fistulas for hemodialysis: a randomized trial.

BACKGROUND AND OBJECTIVES Arteriovenous fistulas (AVFs) are the preferred vascular access for hemodialysis but have a considerable failure rate. This study investigated whether routine preoperative vascular ultrasound results in better AVF outcome than physical examination. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS Patients with end-stage kidney disease referred for permanent access forma...

How to Perform the Complete Abdominal Ultrasound Examination

At our institution, an abdominal ultrasound is typically the first imaging test performed when perforation of the lower urinary tract is suspected. However, the location of the perforation is almost impossible to determine with ultrasound. As a result, some sort of positive contrast study is usually performed when a uroabdomen or uroretroperitoneum is present. For the urinary bladder or urethra...
