OBJECTIVE 68Ga-1,4,7,10-Tetraazacyclododecane-N,N',N'',N'''-tetraacetic acid (DOTA)-F(ab')2-trastuzumab [68Ga-DOTA-F(ab')2-trastuzumab] has been developed at our institution as a positron imaging reagent for assessing human epidermal growth factor receptor 2 (HER2) expression status by in-vivo imaging. Initial studies on animals demonstrated promising results in the monitoring of treatment resp...
Abstract Background Nearly all meningiomas express somatostatin receptor 1/2 (SSTR1/SSTR2); therefore, SSTR ligands such as 68Ga-DOTATATE can be utilized for meningioma radiotherapy treatment planning. Incorporation of PET assists with target delineation and may reduce the dose to organs-at-risk (OARs). We hypothesize that PET-based plans will OARs when compared MRI-based plans. METHODS All wer...
Background The widespread acceptance and application of 68Ga-PET depends on our ability to develop radiopharmaceuticals that can be prepared in a convenient and suitable manner. A kit-type labelling protocol provides such characteristics and requires chelators that can be radiolabelled under exceptionally mild conditions. Recently the DATA chelators have been introduced that fulfil these requir...
The diagnosis of myocarditis traditionally relies on invasive endomyocardial biopsy but none of the imaging studies so far are specific for infiltration of the inflammatory cells itself. We synthesized 68Ga-2-(p-isothiocyanatobenzyl)-1,4,7-triazacyclononane-1,4,7-triacetic acid (NOTA) mannosylated human serum albumin (MSA) by conjugating human serum albumin with mannose, followed by conjugation...
The construction of the 68Ge/68Ga generator has increased application of radiopharmaceuticals labeled with this isotope in medicine. 68Ga-PET is widely employed in the management of neuroendocrine tumors but favorable chemistry with tri- and tetraaza-ring molecules has opened wide range of 68Ga application in other fields of PET imaging. This review covers the radiopharmaceuticals labeled with ...
OBJECTIVE Intraplaque neovascularization contributes to the progression and rupture of atherosclerotic lesions. Glutamate carboxypeptidase II (GCPII) is strongly expressed by endothelial cells of tumor neovasculature and plays a major role in hypoxia-induced neovascularization in rodent models of benign diseases. We hypothesized that GCPII expression may play a role in intraplaque neovasculariz...
T he SNMMI 2018 Mid-Winter Symposium and American College of Nuclear Medicine (ACNM) Annual Meeting will be held at the Hilton Orlando Lake Buena Vista in Orlando, FL. This year, the SNMMI format will be different. Now called a symposium, it will have a single track on theranostics and will begin on Thursday afternoon, January 25, and conclude on Saturday evening, January 27—eliminating Sunday ...
Pulmonary carcinoids are histologically classified into typical and atypical. It is important to identify these preoperatively for treatment planning and prognosis. Structural imaging cannot conclusively differentiate between them. The aim of this study was to assess the possibility of differentiating the 2 variants using [18F]fluorodeoxyglucose (FDG)-positron emission tomography (PET)/computed...
