Acuity of biopsy needles.
The acuities of the conventional biopsy device and of a new design of biopsy needle holder were determined in an in vitro study using fresh pork kidney. A second study, using fresh beef kidney, evaluated the effect of different surface treatments on the acuity of biopsy needles. Only minor clinical differences were found in the acuities of the two types of biopsy needle. It was established, however, that silicone surface treatment and cryogenic treatment of biopsy needles significantly increases their acuity.
