OBJECTIVES Although positron emission tomography (PET) using [(18)F]-fluoro-2-deoxy-D-glucose ((18)F-FDG) is established as one of the first-choice imaging modalities in the diagnosis of chest malignancies, there are several problems to solve in clinical practice, such as false positive uptake in inflammatory diseases. The aim of this study was to evaluate(More)
123I-Iomazenil (123I-IMZ) and 123I-IMP imaging were performed in 8 epileptic patients (EP) in the interictal phase and 6 normal volunteers (NV). On 123I-IMZ delayed imaging, the 8 EP showed abnormally decreased findings. Two EP showed decreased perfusion in the same region on 123I-IMP imaging. 123I-IMZ imaging for the detection of epileptic foci showed(More)
123I-Iomazenil (123I-IMZ) and 123I-IMP imaging were performed in 5 patients with anxiety disorder (PAD) and 6 normal volunteers (NV). On 123I-IMZ delayed imaging, the 2 PAD showed abnormally decreased findings. In anxiety disorder, decreased accumulation on 123I-IMZ delayed images was seen in left hippocampus and parahippocampal gyrus in one patient, in(More)
This paper deals with a study to obtain the optimal sequence of gradient echo (GE) for T1- and T2*-weighted images similar to T1- and T2-weighted images of spin echo (SE). Two GE sequences, fast low angle shot (FLASH) and fast imaging with steady-state precession (FISP), were performed in 15 cases of liver metastasis in various combination of flip angle(More)
