Comparison of Bone Marrow Biopsy Specimens Obtained Using a Motorized Device and Manual Biopsy Systems.

Objective: Bone marrow biopsy is an essential component in the diagnosis of hematopoietic disorders. Researchers evaluated the quality of bone marrow biopsy tissue acquired with a motorized bone marrow biopsy device versus a standard manual device based on the following criteria: biopsy length, percentage of aspiration artifact/intrastromal hemorrhage, length of nonhematopoietic bone, and overall quality of the sample.

Methods: Bone marrow biopsies (motorized, = 30; manual, = 120) from two academic medical centers were evaluated by two board-certified hematopathologists.
