Percutaneous Ultrasound-Guided Core Needle Biopsy: Comparison of 16-Gauge versus 14-Gauge Needle and the Effect of Coaxial Guidance in 1065 Breast Biopsies – A Prospective Randomized Clinical Noninferiority Trial

Abstract

The diagnostic accuracy and quality of ultrasound-guided 16-gauge core needle biopsy were inferior to the 14-gauge needle size, regardless of the use of a coaxial technique.
