Philips has introduced the Philips Abdominal Aortic Aneurysm (AAA) Model. Based on 3D ultrasound, Philips AAA Model provides accurate diagnostic information without exposing patients to high radiation doses and nephrotoxic contrast agents.
AAAs are usually identified incidentally during abdominal imaging exams but sometimes go unnoticed until rupture. A ruptured AAA has an 80 percent mortality rate1. Philips AAA Model integrates software and the firm’s proprietary 3D ultrasound technologies into a single solution to help increase diagnostic confidence and improve patient experience. The software automatically segments and quantifies the size of the aneurysm sac for surveillance of known native and post-EVAR AAAs.
A recent clinical study showed 3D ultrasound examination for native AAA surveillance has excellent inter-operator reproducibility, superior to 2D ultrasound, supporting the broader use of 3D ultrasound in standard AAA surveillance programs2. 3D ultrasound has been shown to estimate the diameter and volume of an AAA with acceptable reproducibility and an improved agreement (over 2D ultrasound) with CT3. 3D ultrasound has also been proven to correlate significantly better to 3D CT than 2D ultrasound for assessing the residual sac’s maximum diameter post-EVAR, with clinically acceptable reproducibility4.
“Regular surveillance of abdominal aortic aneurysm patients is essential, but today’s standard of care has downsides,” Bich Le, senior VP and GM, Ultrasound at Philips. “Philips Abdominal Aortic Aneurysm (AAA) Model seamlessly integrates leading Philips technologies including Philips Premium Ultrasound System (EPIQ Elite), Philips Array Transducer (X6-1 xMATRIX) and innovative software into a single solution, to help improve the experience and outcomes for clinicians and patients alike.”
The Philips AAA Model is CE marked and is FDA cleared.
