In this episode, Dr. David Guez discusses the advancements in contrast enhanced ultrasound, its application in detecting endoleaks, and his journey of learning and applying this modality from residency to his current practice.

Dr. Guez emphasizes ultrasound’s utility in lesion characterization, endoleak monitoring, and sparing patients from more invasive diagnostic procedures. The doctors delve into the specifics of using ultrasound contrast agents, particularly LUMASON and its intravascular utility for real-time monitoring of disease states with superior resolution compared to CT or MRI. Dr. Guez also discusses the potential for contrast enhanced ultrasound in interventional radiology, including diagnosing vascular lesions and augmenting tumor treatments. The conversation highlights the technique’s advantages, its high sensitivity for endoleaks, and potential areas for future research and application. The episode underscores the underutilized potential of contrast enhanced ultrasound in both diagnostic and interventional radiology settings.
