introduction: differentiation between infection and sterile inflammation is one of the most difficult medical problems and is relevant in many clinical situations. scintigraphy with radiolabeled antibiotics, еspecially labeled fluoroquinolones, is a promising tool for diagnosing bacterial inflammation. we have attempted to synthesize 99mtc-norfloxacin and studied its properties in experiment. m...
INTRODUCTION Oncolytic viruses show promise for treating cancer. However, to assess therapy and potential toxicity, a noninvasive imaging modality is needed. This study aims to determine the in vivo biodistribution, and imaging and timing characteristics of a vaccinia virus, GLV-1h153, encoding the human sodium iodide symporter (hNIS. METHODS GLV-1h153 was modified from GLV-1h68 to encode the...

Stannous dichloride (SnCl(2)) occurs in the environment where it has been especially enriched in aquatic ecosystems. Furthermore, it is used in food manufacturing (e.g. for stabilizing soft drinks or as an anti-corrosive substance) and in nuclear medicine where it is employed as a reducing agent for technecium-99m (99mTc) and therefore is applied intravenously to human beings. SnCl(2) is known ...
کد mcnp4c برای شبیه سازی ریه استفاده شد. در این مطالعه، نارسائی ریه به صورت تئوری بررسی شد. بافت های ریه و نای با استفاده از کد mcnp4c شبیه سازی شد و فرض شد که شامل tc-99m به عنوان چشمه رادیواکتیو با انرژی kev 140 بودند. ما فانتوم ها را تعریف کردیم که یک ریه و یک تومور کروی داشت(ریه چگالی g/cm3 0.296 کد mcnp4c برای شبیه سازی ریه استفاده شد. در این مطالعه، نارسائی ریه به صورت تئوری بررسی شد. باف...
OBJECTIVE To report oncological cases (excluding those related to breast cancer) for which radioguided surgery has been used in combination with the Radioguided Occult Lesion Localization technique. INTRODUCTION Radioguided surgery enables a surgeon to identify lesions or tissues that have been preoperatively marked with radioactive substances. The Radioguided Occult Lesion Localization techn...
Penangkapan non-osseous pada pemeriksaan sidik tulang dengan menggunakan radiofarmaka Technetium-99m methylene diphosphonate (Tc-99m MDP) dapat disebabkan karena proses neoplasma, trauma, inflamasi, iskemik, dan artefak. Perubahan metabolisme lesi diketahui pencitraan Tc-99m MDP. Lesi jaringan lunak terlihat adanya peningkatan aktivitas area fokal. Tujuan penulisan telaah pustaka ini adalah unt...
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...
(99m)Tc-Tetrofosmin ((99m)Tc-TF) and (99m)Tc-Sestamibi ((99m)Tc-MIBI) are SPECT tracers that have been used for brain tumor imaging. Tumor's multidrug resistance phenotype, namely, P-glycoprotein (p-gp), and the multidrug resistance related proteins (MRPs) expression have been suggested to influence both tracers' uptake. In the present study we set out to compare (99m)Tc-TF and (99m)Tc-MIBI upt...
