Abstract Open hepatic and renal biopsies were performed in 15 healthy pygmy pigs by each of 15 different commonly used needles/automated biopsy devices (guns). These biopsies were performed by three radiologists, each with widely varying prior experience in the use of each device. These 15 biopsy needles/biopsy guns were divided into six categories and compared in a multivariate model to assess differences in radiologist performance based upon their prior experience. The performance of individual radiologists varied the most with the group of aspiration needles. Even an experienced radiologist who had previously performed 55 such biopsies performed statistically worse than another radiologist who had performed in excess of 200. The biopsy guns, as a group, also demonstrated significant variability between radiologists and their experience level. However, when considered alone, experience appeared less a factor with the Bard 18-gauge (1.20 mm) long-throw biopsy gun. Considerable experience-related variability was also encountered in the liver with the Vim Silverman needle and in the kidney with the vacuum needles. The 14 gauge (2.00 mm) Tru-Cut needle provided a high-quality specimen seemingly independent of operator experience. Regardless of the needle or device used, prior experience in their use appears most important in biopsies of softer, less fibrous, and more vascular tissue.
