Clinical Imaging Characteristics of the Positron Emission Mammography Camera: PEM Flex Solo II
The Journal of Nuclear Medicine, 09/24/09

MacDonald L et al. – A reconstructed spatial resolution of 2.4 mm represented a significant improvement over conventional whole–body PET scanners and should reduce the lower threshold on lesion size and tracer uptake for detection in the breast. Limited–angle tomography and a lack of data corrections result in spatially variable quantitative results. PEM acquisition geometry limits sampling statistics at the chest–wall edge of the camera, resulting in high variance in that portion of the image. Example patient images demonstrate that lesions can be detected at the chest–wall edge despite variance artifacts, and fine structure is visualized routinely throughout the FOV in the focal plane.
