Abstract:
A modified coaxial technique for the biopsy of small or deeply situated lesions using computed tomographic (CT) guidance is described. A 22-gauge needle was passed coaxially through an outer 18-gauge introducing needle and aspiration biopsy was performed. This modified coaxial technique allows for multiple biopsies to be obtained safely, expeditiously, and repeatedly.
