A study comparing the adequacy rates of the BioPince (Argon Medical, Frisco, TX; n = 53) 16-gauge and Achieve (Becton Dickinson, Franklin Lakes, NJ; n = 141) 18-gauge biopsy needles for percutaneous liver biopsy in patients with parenchymal liver disease found that the BioPince needle acquired a significantly greater total core length and a great number of portal tracts, with significantly improved adequacy rates and no major complications.
