Dopamine plays an important role in the development of alcohol dependence, cognitive dysfunction, and is regulated via dopamine transporter activity. Although dopamine transporter activity is critically involved in alcohol dependence, studies observing this relationship are limited. Thus the current study examined whether dopamine transporter availability is associated with developing of alcoho...

OBJECTIVE Studies of laboratory animals have shown that administration of antidepressants of all pharmacological classes produces changes in dopamine transporter binding affinity. These observations suggest that dopamine transporter function may play a critical role in the pathophysiology of depression. The present study was an examination of the availability of brain dopamine transporter sites...

Introduction: 99mTc-TRODAT-1 is a promising new radiopharmaceutical with the potential for routine use as the radiopharmaceutical for dopamine transporters scintigraphy as far as its image quality and daily availability are concerned. Here we describe the development of a freeze-dried kit formulation based on the tricine exchange labeling approach for the preparation of this radiopha...

OBJECTIVE The aim of this study was to compare the renal function measured with either 99mTc-DTPA or 99mTc-EC dynamic scintigraphies with that measured using 99mTc-DMSA static scintigraphy. METHODS the values of relative renal function measured in 111 renal dynamic scintigraphies performed either with 99mTc-DTPA (55 studies) or with 99mTc-EC (56 studies) were compared with the relative functi...

Purpose: To demonstrate a rare clinical case of early recurrence verified primary genital lymphoma and the possibility 99mTc-1-Thio-D-glucose (99mTc-TG) SPECT/CT using to brain metastasis diagnosis. Material methods: A patient with diagnosis diffuse large B-cell underwent magnetic resonance imaging (MRI) assess extent disease. Post-treatment follow-up included 18F-FDG PET/CT. diagnose metastasi...

UNLABELLED In vitro transendothelial permeability was compared to in vivo rat single-pass cerebral extractions to evaluate which method would best estimate the blood-brain barrier (BBB) permeability of several SPECT imaging agents. METHOD Six 99mTc complexes and seven non-Tc complexes were tested in vitro using monolayers of primary bovine brain microvessel endothelial cells and in vivo using...

UNLABELLED This study was designed to compare the tracer kinetics between 99mTc-sestamibi and 99mTc-tetrofosmin in a heterogeneous group of 24 patients admitted for routine perfusion imaging. METHODS Twelve patients were studied with 99mTc-tetrofosmin and 12 with 99mTc-sestamibi. In each group, six patients had a low likelihood for coronary artery disease, and six patients had angiographicall...

Treatment of advanced heart failure with implantable LVADs is increasing, driven by profound unmet patient need despite potential serious complications: bleeding, infection, and thrombus. The experimental objective was to develop a sensitive imaging approach to assess early thrombus accumulation in LVADs under operational high flow and high shear rates. Methods: A monomeric bifunctional ligand ...

BACKGROUND Molecular breast imaging (MBI) performed with 99mTc sestamibi has been shown to be a valuable technique for the detection of breast cancer. Alternative radiotracers such as 99mTc maraciclatide may offer improved uptake in breast lesions. The purpose of this study was to compare relative performance of 99mTc sestamibi and 99mTc maraciclatide in patients with suspected breast cancer, u...
