UNLABELLED The aim of this study is to assess the sensitivity of Tc-99m-MIBI for the pre-operative localization of hyperfunctioning parathyroid glands in patients with persistent or recurrent hyperparathyroidism (HPT) after total parathyroidectomy (PTX) with autograft. PATIENTS AND METHODS Tc-99m-MIBI scintigraphy was performed on 7 patients (3 men and 4 women; aged 32 to 62) on hemodialysis ...
OBJECTIVES The aim of this study was to investigate the diagnostic performance of (99m)Tc-hexamethypropylene amine oxime labeled autologous white blood cell ((99m)Tc-HMPAO-WBC) scintigraphy in patients with suspected infections associated with cardiovascular implantable electronic devices (CIEDs). BACKGROUND Early, definite recognition of CIED-related infections combined with accurate localiz...

Human immunodeficiency virus (HIV) infection can cause variable movement disorders, including parkinsonism. HIV-related parkinsonism usually responds well to highly-active antiretroviral therapy (HAART), suggesting a possible reversible dysfunction of the dopaminergic system. We report the case of a 42-year-old man who presented with rapidly progressive symmetric parkinsonism, cognitive decline...
(99m)Tc-Tetrofosmin ((99m)Tc-TF) and (99m)Tc-Sestamibi ((99m)Tc-MIBI) are SPECT tracers that have been used for brain tumor imaging. Tumor's multidrug resistance phenotype, namely, P-glycoprotein (p-gp), and the multidrug resistance related proteins (MRPs) expression have been suggested to influence both tracers' uptake. In the present study we set out to compare (99m)Tc-TF and (99m)Tc-MIBI upt...
The purpose of this study was to examine whether the Tc-99m-ECD SPECT can detect any difference between the brain perfusion in patients with chronic pain and normal controls by means of the Statistical Parametric Mapping (SPM96). The subjects were twelve patients with chronic pain (CP group) and twelve normal controls (NC group). After informed consent was obtained, 720 MBq of Tc-99m-ECD was in...
BACKGROUND We compared SPECT and planar (99m)Tc-MIBI scintimammography (SMM) in the detection of primary breast cancer and metastatic axillary lymph node involvement, and the scintigraphic results with the histopathological/cytological findings. MATERIAL AND METHODS 303 consecutive patients with 308 suspicious or indeterminate lesions observed in mammographies were entered in this study. Afte...
BACKGROUND Disturbances of autonomic function after infarction are associated with both total mortality and sudden death. Although many imaging techniques for assessing the cardiac autonomic nervous system have been studied, the clinical usefulness of these techniques remains uncertain. This exploratory pilot study examined the relationship between abnormalities of ventricular sympathetic inner...
PURPOSE To determine if there was any difference in the ability of physicians to predict prognosis with technetium 99m ((99m)Tc) sestamibi or (99m)Tc tetrofosmin in a large consecutive series of patients at high risk for coronary artery disease who underwent coronary angiography. MATERIALS AND METHODS This study included 1,818 consecutive patients who underwent a rest and stress single photon...
