To assess the feasibility of using estrogen receptor-directed therapy with Auger electron-emitting ligands for therapy of estrogen receptor (ER)-containing cancers, we synthesized and evaluated the radiotoxicity of several 123I-labeled estrogens to specifically kill ER+ cells in culture. Auger electrons have been previously shown to be of short range, generally less than the dimensions of a cel...
The relationship between clinicopathologic diagnosis and 123I-FP-CIT SPECT in 18 patients with dementia (12 with Lewy body disease) from one center in the United States was assessed. The sensitivity and specificity of abnormal 123I-FP-CIT SPECT with reduced striatal uptake on visual inspection for predicting Lewy body disease were 91.7% and 83.3%, respectively. The mean calculated putamen to oc...
123I-metaiodobenzylguanidine (123I-MIBG) is useful for assessment of the severity and prognosis of patients with chronic heart failure (CHF). To examine 123I-MIBG kinetics in the early phase soon after tracer injection, we performed dynamic single photon emission computed tomography (SPECT) in 76 patients with CHF and 17 control subjects. The consecutive 15 images of 2 min-dynamic SPECT were ac...
UNLABELLED The purpose of this study was to evaluate the usefulness in a clinical setting of iodine-123-metaiodobenzylguanidine (123I-MIBG) scintigraphy, planar and single photon emission computed tomography (SPECT) images, in patients with neuroblastoma as detected by a mass screening survey. METHODS 123I-MIBG planar whole body images, and regional SPECT images of patients with neuroblastoma...
BACKGROUND Sugar moieties of gonadotropins play no primary role in receptor binding but they strongly affect their circulatory half-life and consequently their in vivo biopotencies. In order to relate more precisely hepatic trapping of these glycoproteic hormones with their circulatory half-life, we undertook a comparative study of the distribution and elimination of porcine LH (pLH) and equine...
Background: 123I-Metaiodobenzylguanidine ([123I]mIBG) is the agent of choice to assess for presence metastases and therapy response in patients with neuroblastoma.Aim: To [123I]mIBG scan results outcome stage 4 neuroblastoma at our institution.Setting: Red Cross War Memorial Children’s Hospital.Methods: A retrospective review baseline follow-up scans who presented between January 2001 May 2015....
UNLABELLED The purpose of this study was to validate a double-injection (DI) method with N-isopropyl-[123I]p-iodoamphetamine (IMP) to measure regional cerebral blood flow (rCBF) twice in a single session of dynamic SPECT and to elucidate a possible role of this method to identify patients with occlusive disease of major cerebral arteries, who might benefit from cerebral revascularization proced...
BACKGROUND Autonomic alterations in heart failure are associated with an increase in morbimortality. Several noninvasive methods have been employed to evaluate the sympathetic function, including the Meta-Iodobenzylguanidine (123I-MIBG) scintigraphy imaging of the heart. OBJECTIVE to evaluate the cardiac sympathetic activity through 123I-MIBG scintigraphy, before and after three months of car...
ObjectiveTo determine whether susceptibility map-weighted imaging (SMWI) was superior to conventional susceptibility-weighted (SWI) in the diagnosis of Parkinson’s disease (PD) and its correlation with 123I-2bcarbomethoxy-3b-(4-iodophenyl)-N-(3-fluoropropyl)-nortropane single photon emission computerized tomography (123I-FP-CIT SPECT).MethodsBetween May 2017 February 2018, 125 consecutive patie...
two potassium oxalate doped tio2 samples, designated as k1-tio2 and k2-tio2, were synthesized by the base-catalyzed sol-gel process. these samples were impregnated into rubber sheets. two commercial tio2 samples, anatase and degussa p25, were used as reference materials with which the synthesized samples were to be compared. anatase and p25 were also impregnated into rubber sheets and designate...
