Yet there remains much debate as to which particular method of ultrasound-guided diagnostic breast biopsy provides the most accurate and optimal diagnostic information. The aim of the current study was to compare and contrast the 8-gauge vacuum-assisted biopsy approach and the spring-loaded 14-gauge core biopsy approach. Methods A retrospective analysis was done of all ultrasound-guided diagnostic breast biopsy procedures performed by either the 8-gauge vacuum-assisted biopsy approach or the spring-loaded 14-gauge core biopsy approach by a single surgeon from July 2001 through June 2009. Results Among 1443 ultrasound-guided diagnostic breast biopsy procedures performed 724 were by the 8-gauge vacuum-assisted biopsy technique and 719 were by the spring-loaded 14-gauge core biopsy technique. The total number of false negative cases . benign findings instead of invasive breast carcinoma was significantly greater P in the spring-loaded 14-gauge core biopsy group 8 681 as compared to in the 8-gauge vacuum-assisted biopsy group 0 652 0 with an overall false negative rate of 8 386 for the spring-loaded 14-gauge core biopsy group as compared to 0 0 148 for the 8-gauge vacuum-assisted biopsy group. Significantly more P patients in the spring-loaded 14-gauge core biopsy group 81 719 than in the 8-gauge vacuum-assisted biopsy group 18 724 were
