Positron emission mammography (PEM) is an imaging technique designed to provide metabolic visualization of lesions in the breast tissue. The Naviscan high-resolution PEM system is a dual-detector system consisting of two flat, high-resolution detector heads using lutetium yttrium oxyorthosilicate in a 2 x 2 x 13 mm size. The detectors are mounted inside mammogram compression paddles with a 17 x 24 cm field of view. The paddles can be rotated to optimize imaging to match images acquired in standard mammograms. This allows for direct comparison with mammogram images.
