Image-guided percutaneous needle biopsy plays a crucial role in the diagnosis of malignancy. It is more accurate than fine needle aspiration due to its ability to preserve tissue architecture and is less invasive than open surgical biopsy. Percutaneous biopsy permits tissue sampling of almost any body part. As such, an array of available devices exists, each with specific functionality based on the anatomic area to be biopsied. Most common biopsy device categories include aspiration needles, cutting needles, trephine needles, drill-powered devices, and vacuum-assisted devices. Radiologists should be familiar with the components of various biopsy devices. This improves efficiency, increases likelihood of a diagnostic sample and avoids device failure or patient harm.
