An 82-year-old woman presented for routine follow-up PET/CT after undergoing local melanoma resection in the left lower leg, isolated limb infusion chemotherapy, and immunomodulation therapy with Bacillus Calmette-Guérin (BCG) vaccine. Symmetric, bilateral, moderately intense FDG avid axillary and inguinal cutaneous nodules were observed that were new from(More)
A 28-year-old man with a history of Hodgkin lymphoma that was intensely [F-18]fluoro-2-deoxy-D-glucose-avid at diagnosis had achieved complete remission following appropriate therapy. On surveillance positron emission tomography/computed tomography (CT), new, intensely [F-18]fluoro-2-deoxy-D-glucose-avid lesions (lytic on CT) were seen within the vertebral(More)
OBJECTIVE We present the results of the 2015 quality metrics (QUALMET) survey, which was designed to assess the commonalities and variability of selected quality and productivity metrics currently employed by a large sample of academic radiology departments representing all regions in the USA. METHODS The survey of key radiology metrics was distributed in(More)
OBJECTIVES Intermittent unavailability of sincalide for determination of gallbladder ejection fraction (GBEF) prompted increased usage of fatty meal cholecystagogues (FMCs). The aim of this systematic review was to identify the state of current FMC options in cholescintigraphy, focusing on the quality of corresponding normal GBEF values. METHODS We(More)
Ventilation-perfusion scintigraphy (VPS) depicts the two main physiological processes that are fundamental to oxygen-dependent life. The test has affirmed its critical place in the evaluation of patients with lung cancer preparing for lung resection. The results of the study can differentiate patients who are very likely to survive surgery and the(More)
Ventilation-perfusion scintigraphy is routinely performed in patients with suspected pulmonary thromboembolism. Pleural effusions in such patients are common and can cause matched ventilation-perfusion defects. This is especially true of the posterior projections in the supine patient. Prone positioning has been described as a useful technique to(More)
