The authors describe an artifact noted on ultrasound-guided FNA specimens and the artifact was proven to be associated with certain types of ultrasound gel media.
Fine needle aspiration (FNA) procedures often use ultrasound gel, which can create artefacts in the specimens and lead to misdiagnosis of the patient or a non-diagnostic sample.
Ultrasound gel presents a risk of infection when contaminated gel is used in ultrasound-guided needle procedures. Remove the use of gel from ultrasound procedures with Envision.
In this publication, the authors from the Keck School of Medicine of USC report the process and outcome of a clinical study comparing the use of an in-plane fixed-angle needle guide, Ultra-Pro II™ (CIVCO, Kalona, IA), electromagnetic needle tracking, eTRAX™ (CIVCO, Kalona, IA) and freehand technique to preform simulated liver lesion punctures on a humanoid phantom. “Traditionally, radiology residents gain this experience by performing supervised freehand ultrasound-guided procedures on patients who are subjected to potentially longer procedural times and higher complication rates. Emerging guidance technologies, which include in-plane, fixed-angle guidance (IPFA) and electromagnetic needle tracking (ENT), offer the potential to reduce procedure times and complications and therefore improve patient comfort and safety.” The purpose of this study was to quantitatively measure the time from puncture of the skin to successful placement in the lesion and the number of needle passes required to reach the four lesions using each technique.
