Imaging options There are several imaging options capable of identifying and defining breast cancer. These include X-ray mammography, ultrasound, computer tomography (CT), magnetic resonance imaging (MRI) and positron emission tomography (PET). Newer modalities such as positron emission mammography (PEM) or near infrared spectroscopy (NIRS), recently or soon to be available in clinical practice...

Positron emission mammography (PEM) is a form of positron emission tomography (PET) that uses a high-resolution, mini-camera detection technology for imaging the breast. As with PET, PEM provides functional rather than anatomic information on the breast. This policy will address the use of PEM for presurgical planning and staging, monitoring response to therapy, and monitoring for recurrence of...

Several imaging modalities have been introduced over recent years to better screen for and stage breast cancer. Positron emission mammography (PEM) has been approved by the US Food and Drug Administration and introduced into clinical use as a diagnostic adjunct to mammography and breast ultrasonography. PEM has higher resolution and a more localized field of view than positron emission tomograp...

UNLABELLED We evaluated a commercial positron emission mammography (PEM) camera, the PEM Flex Solo II. This system comprises two 6 x 16.4 cm detectors that scan together covering up to a 24 x 16.4 cm field of view (FOV). There are no specific standards for testing this detector configuration. We performed several tests important to breast imaging, and we propose tests that should be included in...

In this paper we present a scatter correction method for a regularized list mode maximum likelihood reconstruction algorithm for the positron emission mammograph (PEM) that is being developed at our laboratory. The scatter events inside the object are modelled as additive Poisson random variables in the forward model of the reconstruction algorithm. The mean scatter sinogram is estimated using ...
