Quantitative assessment of truncal FDG-PET examination with postinjection transmission scan--comparison with preinjection transmission scan.
UNLABELLED The purpose of this study was to assess the quantitative accuracy of truncal FDG PET with a postinjection transmission scan. METHODS Ten subjects with lung cancer were recruited for this study. Prior to the emission scan, a transmission scan was performed for 10 min. All subjects received 370 MBq of intravenous administration of FDG prior to a 60-min emission scan. Immediately foll...
متن کاملAttenuation correction in myocardial perfusion SPECT using sequential transmission - emission scanning with 99mTc [Persain]
Introduction: Nowadays, Imaging of the myocardial perfusion (MPI) using the single photon emission tomography (SPET) in the diagnosis of coronary artery disease, especially myocardial ischemia, is of great importance. In contrast to the coronary artery angiography, MPI is non-invasive, less expensive and more physiological. Unfortunately, this image is affected by the some artifacts. Thes...
متن کاملAccuracy of cardiac PET imaging using post-injection transmission scan.
UNLABELLED The purpose of this study was to investigate the accuracy of cardiac PET with post-injection transmission scans. METHODS We performed a phantom study using 18F solution as well as 13N-ammonia PET study of ten patients. The average activities of no myocardial defect phantom model were estimated, and myocardial defect sizes of 12 phantom models were measured by pre- and post-injectio...
متن کاملDetermination of Uterus Absorbed Dose by Patients following Myocardial Perfusion Scan using TLD and Conjugate View Methods
Introduction: The determination of patient’s absorbed dose is the first step of radiation protection which depends on the quantification of organ activity in nuclear medicine. The aim of the present study was to determine the absorbed dose by patient’s uterus following myocardial perfusion scan with 99mTC-sestamibi using Theroluminescnce dosimetry (TLD) and conjugate-view metho...
متن کاملPostinjection Muscle Fibrosis from Lupron
We describe the case of a 6.5-year-old girl with central precocious puberty (CPP), which signifies the onset of secondary sexual characteristics before the age of eight in females and the age of nine in males as a result of stimulation of the hypothalamic-pituitary-gonadal axis. Her case is likely related to her adoption, as children who are adopted internationally have much higher rates of CPP...
