Retroperitoneal Biopsy Using eTRAX™ Needle Tip Tracking

Case: Retroperitoneal Biopsy
Featured Product: eTRAX Needle Tip Tracking System
CONSIDERATION FOR USE
Using Volume Navigation on the LOGIQ E9, image fusion of 2D ultrasound and CT made it possible to visualize a difficult target. Using eTRAX Needle Tip Tracking was beneficial to obtain proper access to the obscurred target and continuously visualize the needle tip as it was advanced.
EQUIPMENT FOR EXAMINATION
GE Healthcare LOGIQ E9 with Volume Navigation
CIVCO eTRAX Needle Tip Tracking
APPROACH TO EXAMINATION
Electromagnetic sensor technology and graphical software guidelines representing the real-time trajectory of the needle path allowed for continuous needle tip visualization throughout this challenging procedure. In this patient, the ultrasonic window was difficult and the target area of interest was nearly obscured. Additionally, the location was in a critical region near the aorta. The eTRAX Needle Tip Tracking system provided an anatomical roadmap and when combined with the CT dataset, allowed access to the previously inaccessible target.
Aided by the on-screen guidelines of eTRAX Needle Tip Tracking, continuous visualization of the needle tip was obtained despite a difficult ultrasonic window.
