This proposal for standardization of 123I-metaiodobenzylguanidine (iobenguane, MIBG) cardiac sympathetic imaging includes recommendations for patient information and preparation, radiopharmaceutical, injected activities and dosimetry, image acquisition, quality control, reconstruction methods, attenuation, scatter and collimator response compensation, data(More)
OBJECTIVE The authors' goal was to study striatal dopaminergic dopamine 2 (D(2)) receptors as a biological marker of early relapse in detoxified alcoholic patients by using [(123)I]iodobenzamide ([123I]IBZM) single photon emission computed tomography (SPECT). METHOD The authors performed [(123)I]IBZM SPECT on 21 alcohol-dependent inpatients during(More)
Positron Emission Tomography (PET) is a significant advance in cancer imaging with great potential for optimizing radiation therapy (RT) treatment planning and thereby improving outcomes for patients. The use of PET and PET/CT in RT planning was reviewed by an international panel. The International Atomic Energy Agency (IAEA) organized two synchronized and(More)
Fifteen patients with breast cancer and skeletal metastases who had bone pain refractory to opioid analgesics and who were not eligible for or had not responded to local field radiotherapy, were treated with strontium-89. All patients had received previous treatment with chemotherapy and radiotherapy for bone metastases. Severity of bone pain, sleeping(More)
Technetium-99m dimercaptosuccinic acid (DMSA) study has been advocated as a method for the assessment of renal sequelae after acute febrile urinary tract infection (UTI). However, it is not known whether DMSA scintigraphy performed during acute UTI has any prognostic value for outcome assessment. The objective of this study was to evaluate the usefulness of(More)
Cardiac sympathetic neuronal function and activity can be assessed noninvasively by the use of I-metaiodobenzylguanidine (I-MIBG), an analogue of norepinephrine [1]. In the past two decades, a large number of investigators have demonstrated decreased myocardial I-MIBG uptake in patients with chronic heart failure (CHF) and have shown that those with the(More)
The sympathetic nervous system has great influence on cardiovascular physiology, and the importance of cardiac innervation abnormalities in the physiopathology of various cardiac diseases has been emphasized. Cardiac neurotransmission imaging with single-photon emission computed tomography (SPECT) allows in vivo assessment of the myocardial nervous system.(More)
UNLABELLED The recent introduction of the opioid antagonist naltrexone for alcohol-dependence therapy has been mainly based on behavioral animal models that provide evidence of the involvement of the endogenous opioid system in alcohol drinking and dependence. However, the neurophysiological mechanisms of the effect of naltrexone in alcoholic patients(More)
