The Role of Dead Space Length in Biopsy Needles: Image-Guided Percutaneous Core Needle Biopsy: Engineering, Physics, and Clinical Implications

Abstract

Image-guided biopsy serves as a pivotal diagnostic modality in the realm of pathologic evaluation. Although considerable scrutiny is often devoted to the needle’s cutting length and throw length, the segment known as the "Dead Space Length" frequently remains under- investigated or defined. This manuscript endeavors to elucidate the engineering principles,biomechanical attributes, and clinical ramifications associated with Dead Space Length in biopsy needles. Specifically, we focus on its consequential impact on procedural safety metrics and the integrity of acquired tissue samples.
