A percutaneous transvascular angioplasty (PTA) is performed to relieve failed vascular access for hemodialysis. Angiography using non-ionic iodinated contrast media is the imaging modality of choice for performing PTA. However, the use of iodinated contrast media is contraindicated for patients with a history of iodine allergy. Since 1920, carbon dioxide (CO(2)) has been used as a safe contrast...
introduction: iodine deficiency disorders (idd) are the most common epidemiological problems in the world, including our country. in order to prevent idd and its consequences, iodized table salt is being used in our country since 1989. at present, this program is 18 years old. the surveillance of idd may be implemented to assess the prevalence of idd, identify high risk areas for intervention a...
BACKGROUND In radiotherapy treatment planning, intravenous administration of an iodine-based contrast agent during computed tomography (CT) improves the accuracy of delineating target volumes. However, increased tissue attenuation resulting from the high atomic number of iodine may result in erroneous dose calculations because the contrast agent is absent during the actual procedure. The purpos...
T HAS BEEN OUR EXPERIENCE (1) that accurate measurement on large numbers of samples in a minimum amount of working time per specimen can be achieved consistently in the analysis of protein-bound iodine by means of alkaline incineration. However, with the use of incineration, where many samples may be exposed simultaneously in enclosed spaces such as centrifuges, drying ovens, and muffle furnace...
UV-vis and Raman spectroscopy were used to study iodine molecules trapped in sII clathrate hydrate structures stabilized by THF, CH(2)Cl(2), or CHCl(3). The spectra show that the environment for iodine inside the water cage is significantly less perturbed than either in aqueous solution or in amorphous water-ice. The resonance Raman progression of I(2) in THF clathrate hydrate can be observed u...
