UNLABELLED (99m)Tc-[bis (dimethoxypropylphosphinoethyl)-ethoxyethylamine (PNP5)]-[bis (N-ethoxyethyl)-dithiocarbamato (DBODC)] nitride (N-PNP5-DBODC or N-DBODC5) is a new monocationic myocardial perfusion tracer. We sought to compare the myocardial uptake and clearance kinetics and organ biodistribution of (99m)Tc-N-DBODC5 with (99m)Tc-sestamibi and (99m)Tc-tetrofosmin. METHODS Seventy-five a...
Purpose: The incident at the Fukushima Daiichi nuclear power station in 2011 has again raised concerns with the public regarding radiation exposure, especially so in medical workers and patients undergoing treatment involving the use of radiation. Radioisotopes are currently used during sentinel node navigation surgery (SNNS) in operating rooms without radiation monitoring. To re-evaluate the s...
A 7-month-old girl with history of persistent left chylous pleural effusion was referred for lymphoscintigraphy. A previous chest computed tomography (CT) scan demonstrated a small to moderate-sized left pleural effusion but could not identify the lymphatic leakage site. Lymphoscintigraphy using filtered (99m)Tc sulfur colloid showed minimal focal activity in the lower chest. A correlative sing...
The one-carbon ring expansion of 1-deoxy-1-thio-1,6-anhydrosugars, mediated by metal carbenes and proceeding through the intermediacy of sulfur ylides, has been proposed as a route for the synthesis of the tagetitoxin skeleton. Intermolecular reactions of such thioanhydrosugars with diazoesters afford a range of undesired products derived from the initially formed ylide, whereas use of an intra...
Ab initio potential energy and dipole moment surfaces are computed for sulfur trioxide (SO3) at the CCSD(T)-F12b level of theory with appropriate triple-zeta basis sets. The analytical representations of these surfaces are used, with a slight correction, to compute pure rotational and rotation-vibration spectra of (32)S(16)O3 using the variational nuclear motion program TROVE. The calculations ...
Objective: The purpose of this study was to retrospectively evaluate microwave heating preparations of "'Tc-sulfur colloid during a 4-wk period. Methods: The mTc-SC kit preparation was performed according to the package insert with microwave heating modifications. Results: During the first 2 wk, patient studies (n = 14) showed excellent images, however during the last 2 wk patient studies (n = ...
