BACKGROUND To prove the feasibility of integrating CT urography (CTU) into 68Ga-PSMA-11 PET/CT and to analyze the impact of CTU on assigning focal tracer accumulation in the ureteric space to either ureteric excretion or metastatic disease concerning topographic attribution and diagnostic confidence. METHODS Ten prostate cancer patients who underwent 68Ga-PSMA-11 PET/CT including CTU because ...
The study assessed a radiolabeled depsipeptide conjugate (68Ga-DOTA-TBIA101) for its potential as an imaging agent targeting infection or infection-associated inflammation. 68Ga-labeled DOTA-TBIA101 imaging was performed in (NZR1) healthy rabbits; (NZR2) rabbits bearing muscular sterile inflammation and Staphylococcus aureus (SA) infection; and (NZR3) rabbits infected with Mycobacterium tubercu...
The early and accurate detection of prostate cancer is important to ensure timely management and appropriate individualized treatment. Currently, conventional imaging has limitations particularly in the early detection of metastases and at prostate-specific antigen (PSA) levels < 2.0 ng/mL. Furthermore, disease management such as salvage radiotherapy is best at low PSA levels. Thus, it is criti...
BACKGROUND The targeting of the prostate-specific membrane antigen (PSMA) is of particular interest for radiotheragnostic purposes of prostate cancer. Radiolabeled PSMA-617, a 1,4,7,10-tetraazacyclododecane-N,N',N'',N'''-tetraacetic acid (DOTA)-functionalized PSMA ligand, revealed favorable kinetics with high tumor uptake, enabling its successful application for PET imaging (68Ga) and radionucl...
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...
Background Lymphoma is a haematological malignancy that affects both old and young. It is the most common indication for PETCT in the young adult. Lymphoma is the fifth commonest malignancy in the UK after breast, lung, colorectal and prostate cancer, accounting for 11,861 cancer cases in 2008 (4%). The current conventional treatments provide good cure rates, with overall 10-year survival rates...
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 ...
