Fujifilm Sonosite has launched PIV Assist, a new artificial intelligence (AI)-powered feature engineered to help clinicians plan peripheral intravenous (PIV) access procedures. The feature will be available on the company’s Sonosite LX, Sonosite PX, and Sonosite ST ultrasound systems.

PIV Assist aids in identifying candidate veins and assessing vein size to offer feedback on the maximum cannula size based on the catheter-to-vein ratio (CVR). It delivers real-time differentiation between veins and arteries during the pre-scan, supporting clinical workflow during vascular access planning.

Veins are color-coded to the maximum recommended catheter gauge, with arteries marked in red to help plan procedures. The CVR visualization feature calculates and displays the catheter-to-vein ratio in real-time, showing the depth to the vein’s center.

PIV Assist’s AI model was developed using tens of thousands of scan images in order to provide reliable vessel support.

“Peripheral IV procedures are among the most common performed on patients, and growing evidence supports ultrasound-guided insertion as a helpful technique, especially for those with difficult IV access,” said Richard Fabian, president and CEO of Fujifilm Sonosite. “At Sonosite, we have a long history of innovation in both education and product development. PIV Assist is an AI-powered tool we developed in close collaboration with our customers. It’s designed to reduce cognitive load and enhance clinician confidence during vascular access planning—both of which are critical to delivering effective patient care.”

Earlier this month, the company launched Sonosite MT, the latest evolution in its line of portable ultrasound systems.
