Naviscan readies PET biopsy

PET niche developer Naviscan arrived at the RSNA meeting with permission from the FDA to launch its Stereo Navigator, a biopsy guidance feature for its breast-specific PET scanner. Stereo Navigator can localize lesions as small as 2 mm. It uses a stereotactic frame fixed between the scanner’s paddles to guide a biopsy needle into the breast. Localization is verified using a PET-visible line source inserted into the needle track. This allows the user to confirm trajectory and position. The PET-guidance accessory is compatible with biopsy devices from Ethicon Endo-Surgery, Hologic, and SenoRx.
