The goal of this teaching case study is to demonstrate the novel use of (99m)Tc-HMPAO-labeled white blood cells (WBCs) in diagnosing chronic recurrent multifocal osteomyelitis (CRMO). (99m)Tc-HMPAO-labeled white blood cells were utilized to diagnose CRMO. Classically, CRMO is evaluated scintigraphically using (99m)Tc-methylene diphosphonate/hydroxymethylene diphosphonate. (99m)Tc-HMPAO-labeled ...
OBJECTIVE The optimization of medical exposure is one of the major issues regarding radiation protection in the world, and The International Committee of Radiological Protection and the International Atomic Energy Agency recommend establishing diagnostic reference levels (DRLs) as tools for dose optimization. Therefore, the development of DRLs based on the latest survey has been required for nu...
Ubiquicidin 29-41 (UBI 29-41) is an antimicrobial peptide with six positively charged residues which preferentially binds to the negatively charged groups present on the microbial membrane by electrostatic interaction at the foci of infection. For this reason UBI 29-41 has been suggested to label by 99m Tc ( 99m Tc-UBI 2941)directly or by using coligand reagents like 6-hydrazinopyridine 3-carbo...
Exosomes known as nano-sized extracellular vesicles attracted recent interests due to their potential usefulness in drug delivery. Amid remarkable advances in biomedical applications of exosomes, it is crucial to understand in vivo distribution and behavior of exosomes. Here, we developed a simple method for radiolabeling of macrophage-derived exosome-mimetic nanovesicles (ENVs) with (99m)Tc-HM...
UNLABELLED Technetium-99m dimercaptosuccinic acid (Tc-99m DMSA) as a static renal agent is currently the most frequently used agent in the detection of renal scarring, and allows accurate calculation of differential renal function (DRF). But this agent has some disadvantages such as relatively higher radiation dose and time consumption. METHODS The purpose of this study was to evaluate the po...
This review describes the application of 2 nuclear imaging techniques for assessment of hepatic function in the setting of liver surgery and transplantation. The biochemical and technical background, as well as the clinical applications, of (99m)Tc-labeled diethylenetriaminepentaacetic acid galactosyl human serum albumin (GSA) scintigraphy and hepatobiliary scintigraphy (HBS) with (99m)Tc-label...
Tc-99m PMT and Tc-99m GSA can be taken up by hepatocellular carcinoma (HCC), but there has been no report concerning HCC showing accumulation of both of Tc-99m PMT and Tc-99m GSA. In this paper we describe a case of two simultaneously developed HCCs, one of which took up both tracers but the other took up neither of them.
