یْد-123 یکی از رادیوایزوتوپهای شناخته شده در پزشکی هستهای است که برای مطالعة غده تیروئید و متاستازهای آن بکار میرود. این رادیوایزوتوپ در سیکلوترون از بمباران گاز زینون-124 غنی شده به وسیلة پروتون تولید میشود. از آنجایی که یکی از موارد مصرف این رادیوایزوتوپ کپسول خوراکی یْدید سدیوم است بر آن شدیم تا با استفاده از یْد-123 تولید شده، کپسول خوراکی آن را تهیه کنیم. پس از بمباران و شستشوی هدف، با ب...
PURPOSE To evaluate the potential utility of (123)I-metaiodobenzylguanine ((123)I-MIBG) scintigraphy and (18)F-fluorodeoxyglucose ((18)F-FDG) positron emission tomography (PET) for the detection of primary and metastatic lesions in pediatric neuroblastoma (NBL) patients, and to determine whether (18)F-FDG PET is as beneficial as (123)I-MIBG imaging. METHODS We selected 8 NBL patients with sig...
INTRODUCTION (123)I-N-isopropyl-p-iodoamphetamine ((123)I-IMP) is metabolized and converted to (123)I-p-iodoamphetamine ((123)I-PIA) by CYP2C19 in humans. Since variations in (123)I-PIA levels reflect variations in CYP2C19 activity, CYP2C19 activity can be estimated by quantitative analysis of (123)I-PIA levels. Thus, (123)I-IMP administration can provide diagnostic information not only regardi...
UNLABELLED (123)I-ADAM (2-([2-([dimethylamino]methyl)phenyl]thio)-5-(123)I-iodophenylamine) has been recently proposed as a new serotonin transporter (SERT) ligand for SPECT. The objective of this study was to characterize (123)I-ADAM in healthy volunteers. (123)I-ADAM distribution in the normal brain, pseudoequilibrium interval after a single injection, normal specific uptake values, and long-...
PURPOSE To report the development and validation of a technique of dual tracer single-photon emission CT brain imaging using technetium-99m hexamethylpropyleneamine oxime and iodine-123 iodoamphetamine agents and the application of this technique in patients with a variety of diagnoses. METHODS Contamination between the two isotopes' energy windows was calculated by opening both energy window...
Preferential retention and cytotoxicity of Rhodamine-123 (Rho-123) was originally reported in a number of carcinoma cell types isolated from a variety of tissues as compared to normal epithelial cells from a limited number of other tissues. In the present study, we have examined Rho-123 selectivity in normal and tumor cell lines isolated from the same tissue source, i.e., human breast. We found...
OBJECTIVE It is recognized that diagnostic doses of (131)I larger than 3 mCi will cause some cell injury to the tissue in which it concentrates and reduce subsequent uptake of (131)I administered therapeutically. Iodine-123 has been suggested as an alternate radiopharmaceutical to perform whole-body scans since its primary emissions are photons with minimal particulate radiation and it does not...
Pleiotropic resistance to rhodamine 123 (Rho-123) in Adriamycin (ADM)-resistant Friend leukemia cells was circumvented by cotreatment with 10 microM verapamil. Increased cytotoxicity corresponded to higher intracellular Rho-123 levels. The verapamil-induced increase of drug accumulation in resistant cells is accounted for at least in part by the blockage or slowing of Rho-123 efflux from these ...
