OBJECTIVE The study objective was to assess the correlation between (18)F-FDG uptake values on positron emission mammography (PEM), expressed as maximum uptake value and lesion-to-background ratio, and receptor status (i.e., estrogen receptor [ER], progesterone receptor [PR], and human epidermal growth factor receptor 2 [HER2]), tumor histology, and tumor(More)
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(More)
OBJECTIVE The aim of this article is to evaluate gastric motility and emptying in the ictal and interictal period in migraine. BACKGROUND Nausea is a predominant symptom of migraine and the basis of it is thought to be gastric stasis. Objective methods to establish this are however lacking. We utilized gastric scintigraphy studies to determine gastric(More)
The skeleton is one of the most common sites for metastatic disease, particularly from breast and prostate cancer. Bone metastases are associated with considerable morbidity, and accurate imaging of the skeleton is important in determining the appropriate therapeutic plan. Sodium fluoride labeled with fluorine 18 (sodium fluoride F 18 [(18)F-NaF]) is a(More)
To the Editor: F-18 fluorodeoxyglucose positron emission tomography with fused computerized tomography (PET–CT) has become a mainstay of staging in a wide array of malignancies (1,2). However, for those patients with breast cancer, the role of PET–CT for systemic staging is less clear (3–5). Recent investigations of the utility of PET and PET–CT imaging in(More)
PURPOSE To characterize the relationship between lesion detection sensitivity and injected activity as a function of lesion size and contrast on the PEM (positron emission mammography) Flex Solo II scanner using phantom experiments. METHODS Phantom lesions (spheres 4, 8, 12, 16, and 20 mm diameter) were randomly located in uniform background. Sphere(More)
UNLABELLED We studied the effects of reduced (18)F-FDG injection activity on interpretation of positron emission mammography (PEM) images and compared image interpretation between 2 postinjection imaging times. METHODS We performed a receiver-operating-characteristic (ROC) study using PEM images reconstructed with different count levels expected from(More)
