BACKGROUND CT has evolved as the gold standard for evaluation of head injury, but early CT is not always possible. Bedside ultrasonography is available in most trauma units and optic nerve ultrasound (ONUS) examination should be feasible. OBJECTIVE To evaluate the role of ONUS for people with head injury. SETTING Tertiary care trauma service in a(More)
Aromatase, cytochrome P450 19, is a key enzyme in the biosynthesis of estrogens by the human placenta. It is also the major placental enzyme that metabolizes the opiates L-acetylmethadol (LAAM), methadone, and buprenorphine (BUP). Methadone and BUP are used in treatment of the opiate addict and are competitive inhibitors of testosterone conversion to(More)
OBJECTIVES Primary primitive neuroectodermal tumor (PNET) of the kidney is an extremely rare entity and the case is presented to highlight the histological diagnostic problems. METHODS AND RESULTS A 23-year-old female presented with a lump in the left hypochondrium that had appeared 3 months, earlier, which suggested a malignancy on radiological(More)
Purpose To evaluate the normal biodistribution and kinetics of (S)-4-(3-[18F]fluoropropyl)-l-glutamic acid ((18)F FSPG) in healthy volunteers and to compare (18)F FSPG mean and maximum standardized uptake values (SUVmean and SUVmax, respectively) with those of (18)F fluorodeoxyglucose (FDG) across a variety of organs. Materials and Methods This protocol was(More)
PURPOSE (S)-4-(3-[18F]Fluoropropyl)-L-glutamic acid (18F-FSPG) is a novel radiopharmaceutical for Positron Emission Tomography (PET) imaging. It is a glutamate analogue that can be used to measure xC- transporter activity. This study was performed to assess the feasibility of 18F-FSPG for imaging orthotopic brain tumors in small animals and the translation(More)
Surveillance FDG PET/CT was performed in a 75-year-old woman with history of melanoma and colon cancer. She had rash and erythematous papules on the forearms, elbows, knees, and thighs and then developed right-leg weakness, difficulty with fine motor movement, and ptosis. Chest CT identified a right-lung spiculated nodule. Skin and pulmonary nodule biopsies(More)
