Optimizing Fine Needle Design to Minimize Needle Tract Seeding in Cancer Diagnosis: A Computational Fluid Dynamics Study

Abstract

This study investigates the optimization of boundary layer flow around fine needles to minimize the potential for needle tract seeding in cancer diagnosis procedures. Needle tract seeding, a common complication in biopsy procedures, occurs when cancer cells spread along the needle tract and can lead to disease recurrence or metastasis. By studying the flow dynamics around fine needles, researchers propose a strategy to minimize the risk of needle tract seeding. The findings of this study may have important implications for improving the safety and efficacy of cancer diagnosis procedures.
