Dual-head gamma camera coincidence imaging in pancreatic cancer.
OBJECTIVE To assess the usefulness of dual-head camera imaging with 2-[fluorine-18]fluoro-2-deoxy-D-glucose (FDG) in the identification of malignant pancreatic lesions. MATERIAL AND METHODS Fifteen (15) patients with pancreatic masses (7 females and 8 males, mean age 52 10 years) have been studied prospectively. After a 12-hour fasting patients received 120 MBq of FDG and were imaged in a dua...
متن کامل[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...
متن کاملCLINICAL INVESTIGATIONS Poststress Motionlike Artifacts Caused by the Use of a Dual-Head Gamma Camera for 201Tl Myocardial SPECT
When performing 201Tl myocardial SPECT using a dual-head gamma camera on patients after exercise stress, we have observed in some a sudden increase in the counting rate between the 16th and 17th images. This increase provoked motionlike artifacts, which increased the number of false-positive findings. The aim of our study was to determine possible causes for this leap in activity. Methods: We p...
متن کاملUsefulness of dual-head coincidence gamma camera with thick NaI crystals for nuclear oncology: comparison with dedicated PET camera and conventional gamma camera with thin NaI crystals.
AIM A comparative study of the images obtained with a dual-head coincidence gamma camera with thick NaI crystals (19 mm), a dedicated PET camera with BGO crystals and a conventional gamma camera with thin NaI crystals (9.5 mm) was conducted to clarify the clinical feasibility of a dual-head coincidence gamma camera with thick NaI crystals. METHODS FDG images of 27 patients with malignant tumo...
متن کاملAssessment of 18F-fluorodeoxyglucose dual-head gamma camera in asbestos lung diseases.
The purpose of this study was to evaluate the performance of 18F-fluorodeoxyglucose (18FDG) imaging via coincidence detection emission tomography (CDET) in identifying malignant lesions in subjects exposed to asbestos. A total of 30 patients exposed to asbestos underwent 18FDG-CDET between January 2000 and June 2003. A CDET scan of the thorax and abdomen was performed 60 min after injection of ...
