full textPositron tomography of breast cancer in a community hospital: A case study of advanced disease using a coincidence gamma camera
Until recently PET scanning has been available only at major universities or teaching hospitals possessing the necessary resources and expertise to operate a research PET facility. Most dedicated PET centers cost several millions of dollars, and include a cyclotron, a radiochemistry laboratory to synthesize PET radiopharmaceuticals, a multicrystal dedicated PET camera, advanced computer f...

full textAttenuation Correction Strategies for Positron Emission Tomography/Computed Tomography and 4-Dimensional Positron Emission Tomography/Computed Tomography.
This article discusses attenuation correction strategies in positron emission tomography/computed tomography (PET/CT) and 4-dimensional PET/CT imaging. Average CT scan derived from averaging the high temporal resolution CT images is effective in improving the registration of the CT and the PET images and quantification of the PET data. It underscores list-mode data acquisition in 4-dimensional ...
full text[Performance evaluation of dual-head coincidence gamma camera for positron imaging].
AIM AND METHODS We assessed the performance evaluation of a dual-head coincidence gamma camera (Millennium VG, General Electric, Milwaukee, USA) as a positron emission tomography (PET) scanner based on the measurement indicator for performance evaluation of PET device. RESULTS The axial spatial resolution was 4.98 mm FWHM at the center of the field of view. The true high count-rate characteri...
