UNLABELLED The alteration of 99mTc-labeled diethylenetriaminepentaacetic acid (DTPA) transalveolar clearance in an initial phase of radiation lung injury was experimentally investigated. METHODS Fourteen dogs were irradiated to the hemithorax with a single dose of 20 Gy. A DTPA radioaerosol study was performed before irradiation and on day 12 after irradiation. On day 14, the DTPA study was r...

The in vivo(212)Pb/(212)Bi generator is promising for application in targeted alpha therapy (TAT) of cancer. One main limitation of its therapeutic application is due to potential release of (212)Bi from the radioconjugate upon radioactive decay of the mother nuclide (212)Pb, potentially leading to irradiation of healthy tissue. The objective of the present work is to assess whether the chelate...

OBJECTIVE-To evaluate use of gadolinium diethylenetriamine pentaacetic acid (Gd-DTPA) to estimate glomerular filtration rate (GFR) by plasma clearance and use of an ELISA as the method of Gd-DTPA quantification. ANIMALS-16 dogs of various sexes and breeds (12 dogs were clinically normal, and 4 dogs were polyuric and polydipsic with no other clinical or biochemical abnormalities). PROCEDURES-GFR...

UNLABELLED Neuroendocrine tumors (NETs) can be visualized using radiolabeled somatostatin analogs. We have previously shown the clinical potential of (64)Cu-DOTATATE in a small first-in-human feasibility study. The aim of the present study was, in a larger prospective design, to compare on a head-to-head basis the performance of (64)Cu-DOTATATE and (111)In-diethylenetriaminepentaacetic acid (DT...

PURPOSE: Hepatobiliary contrast agents add an additional form of image contrast to hepatic magnetic resonance (MR) imaging, allowing differentiation of tumors which have functional hepatic and biliary components from those without. Gd-EOB-DTPA has sufficiently significant elimination via the hepatobiliary pathway to make it a feasible contrast agent in the time allotted to a typical clinical ab...

UNLABELLED In the treatment of neuroendocrine tumors (NETs), complete surgical removal of malignancy is generally desirable, because it offers curative results. Preoperative guidance with radiolabeled somatostatin analogs, commonly used for NET diagnosis and preoperative planning, is limited by its low resolution, with the risk that tumor margins and small metastases will be incompletely resect...

We conducted 3 phase III, randomized, open-label, clinical trials assessing the safety, reactogenicity (all studies), immunogenicity (Primary vaccination study) and persistence of immune responses (Booster study) to the combined diphtheria, tetanus, pertussis, poliomyelitis, and Haemophilus influenzae type b vaccine (DTPa-IPV/Hib) in Chinese infants and toddlers. In the Pilot study (NCT00964028...

It has been repeatedly observed that mixing Haemophilus influenzae type b (Hib) conjugate vaccines with acellular pertussis-containing vaccines (diphtheria-tetanus-acellular pertussis [DTPa]) resulted in a reduced magnitude of the anti-polyriboseribitolphosphate antibody response compared to that obtained when Hib vaccines were administered separately and not mixed. Nevertheless, the quality an...
