Evaluation of Simultaneous Dual-radioisotope SPECT Imaging Using 18F-fluorodeoxyglucose and 99mTc-tetrofosmin
Objective(s): Use of a positron emission tomography (PET)/single-photonemission computed tomography (SPECT) system facilitates the simultaneousacquisition of images with fluorine-18 fluorodeoxyglucose (18F-FDG) andtechnetium (99mTc)-tetrofosmin. However, 18F has a short half-life, and 511keV Compton-scattered photons are detected in the 99mTc energy window.Therefore, in this study, we aimed to ...
متن کاملDual radioisotopes simultaneous SPECT of 99mTc-tetrofosmin and 123I-BMIPP using a semiconductor detector.
Objective(s): The energy resolution of a cadmium-zinc-telluride (CZT) solid-state semiconductor detector is about 5%, and is superior to the resolution of the conventional Anger type detector which is 10%. Also, the window width of the high-energy part and of the low-energy part of a photo peak window can be changed separately. In this study, we used a semiconductor detector and examined the ef...
متن کاملSimultaneous Dual-Isotope SPECT Imaging for the Detection and Characterization of Parathyroid Pathology
V a r i o u s imaging methods have been used for the preoperative localization of parathyroid tumors in patients with hyperparathyroidism. Among the noninvasive methods, several scintigraphic techniques have been employed, including variations on the dual-isotope 2°ITI/99mTC subtraction techniques (1-3). Modification of this technique, using 123I instead of [99mTC] pertechnetate, has also been ...
متن کاملSimultaneous dual-isotope SPECT imaging for the detection and characterization of parathyroid pathology.
A technique is described involving simultaneous, dual-isotope SPECT imaging. Using 123I and 201TI, a patient study is presented, demonstrating the clinical utility of this technique in the detection and characterization of parathyroid pathology. The use of this technique in other clinical situations is discussed.
متن کاملComparison of simultaneous dual-isotope multipinhole SPECT with rotational SPECT in a group of patients with coronary artery disease.
UNLABELLED A triple-detector, multipinhole SPECT system was optimally configured to perform simultaneous (201)Tl (stress)/(99m)Tc (rest) myocardial perfusion imaging (MPI) using a protocol that permitted direct diagnostic comparison of this multipinhole SPECT system with conventional rotational SPECT. METHODS Both the rotational and the multipinhole SPECT systems used the same model gamma-det...
