Study Recommends Reduction In Dose For Breast PEM With Preservation Of Image Quality

In a new study presented at the American Association of Physicists in Medicine (AAPM) 52nd Annual Meeting, researchers at the University of Washington reported that 18FDG dose for Positron Emission Mammography (PEM) could be reduced by as much as 70% without affecting image quality. PEM scanners are high-resolution breast PET systems that show the site as well as the metabolic phase of a lesion. The metabolic view enables doctors to take the optimal decision for patient care by providing an unequalled ability to discriminate between benign and malignant lesions, what is called "specificity".

A New Approach For Reducing Radiation Exposure During Cone Beam CT

According to a new study, using a new approach in processing X-ray data would reduce, by nearly 10%, the radiation delivered to patients while undergoing cone beam CT scans. The study was carried out by researchers from the University of California in San Diego. The study will be highlighted at the 52nd Annual Meeting of the American Association of Physicists in Medicine (AAPM) in Philadelphia.

Different Methods Recently Tested For Measuring Breast Density

Three different methods for measuring breast density accurately - through the relative portion of tissue to fat in a woman's breasts and a strong indicator of breast cancer risk- have been tested this week according to two new studies. The two studies were conducted by a group of medical physicists at the University of California, Irvine, led by Sabee Molloi, and both will be presented today and tomorrow at the 52nd Annual Meeting of the American Association of Physicists in Medicine (AAPM) in Philadelphia, PA.
