Cardiovascular positron emission tomography (PET) imaging provides high-quality visual and quantitative myocardial perfusion and function images. In addition, cardiovascular PET can assess myocardial viability, myocardial inflammatory disorders such as cardiac sarcoid, and infections of implanted devices including pacemakers, ventricular assist devices, and prosthetic heart valves. As with all ...

OBJECTIVE The use of PET in Australia has grown rapidly. We conducted a prospective study of the radiation exposure of technologists working in PET and evaluated the occupational radiation dose after implementation of strategies to lower exposure. METHODS Radiation doses measured by thermoluminescent dosimeters over a 2-y period were reviewed both for technologists working in PET and for tech...

Introduction Combining PET with MRI in a hybrid system offers several advantages over PET/CT, namely significantly better soft tissue contrast & resolution and radiation dose reduction for longitudinal studies. Combining conventional PET and superconducting MRI faces many technical challenges, especially the incompatibilities between photomultiplier tube-based (PMT) PET detectors and high magne...

Introduction: Prostate-specific membrane antigen (PSMA) has been demonstrated as a promising tool for specific imaging of prostate cancer (PCa) via positron emission tomography-computed tomography (PET/CT) scanning. Radiation treatment planning (RTP) based on 68Ga-PSMA PET/CT scanning can also lead to some decision modifications.  The specific goal o...

Epidemiologic research shows that pets influence human health, demonstrating both protective and deleterious health risks; therefore, valid definitions of pet exposure would enhance research. The authors determined how well young adults aged 18 years report their early childhood pets. Subjects in an established birth cohort from Detroit, Michigan, born in 1987-1989 (n = 820) were asked a series...

BACKGROUND The relationship between exposure to animals and allergic respiratory diseases in childhood is controversial, and there is little information about how exposure to pets affects the respiratory health of Chinese children, who have lower rates of asthma. OBJECTIVE To study the association between exposure to pets and doctor-diagnosed asthma and asthma-related symptoms in Chinese chil...

Pesticide handlers and pet owners who use products such as shampoos and dips and insecticide-impregnated collars to treat and control fleas on companion animals are exposed to a variety of active ingredients. Chlorpyrifos exposures of adults and children were measured using urine biomonitoring following use of over-the-counter products on dogs. Age and gender-specific measurements of urinary 3,...

Background: PET/CT imaging using [18F]-FDG is utilized in clinical oncology for tumor detecting, staging and responding to therapy procedures. Essential consideration must be taken for radiation staff due to high gamma radiation in PET/CT and cyclotron center. The aim of this study was to assess the staff exposure regarding whole body and organ dose and to evaluate environment dose in PET/CT an...
