Nuclear medicine imaging is routinely used for evaluation of perfusion and function of the transplanted kidneys. At present, the radiopharmaceutical of choice for this study in our center is Tc 99m-Ec. Complications of the kidney graft are demonstrable in the early and delayed images. One of these complications is vesicoureteral reflux to the graft or to the native kidneys. We present a 27 year...

OBJECTIVES Occupational exposure to lead may produce kidney damage, but existing data on the dose range associated with nephrotoxicity are inconclusive. We here assessed renal function under conditions of low to moderate lead exposure using renal scintigraphy. METHODS Fifty-three male foundrymen (exposed group) and fourty male office workers (control group) from a steel plant were included in...
INTRODUCTION L,L-ethylenedicysteine (EC) is a new carrier of technetium Tc 99m (99mTc) with a lower affinity to plasma albumin in comparison with diethylenetriamine pentaacetic acid (DTPA). We compared 99mTc-EC scan with 99mTc-DTPA scan in diuretic renography for patients with obstructive uropathy. MATERIALS AND METHODS Thirty-three patients with upper urinary tract obstruction were randomly ...
BACKGROUND The diagnostic usefulness of parametric clearance kidney images was studied in the early diagnosis of diabetic nephropathy, juxtaposed with conventional dynamic urinary investigation (renoscintigraphy) combined with deconvolution procedure of renal and blood time activity curves and determination of plasma clearance of (99m)Tc-ethylenedicysteine ((99m)Tc-EC). MATERIAL AND METHODS T...
Abstract Introduction The sentinel lymph node (SLN) concept represents advancement in the management of endometrial cancer (EC). We aim to assess performance SLN procedure; its positive predictive value (PPV) and negative (NPV); stage I EC (FIGO2009). Method A prospective study is conducted our institution. perform a double detection (radiolabel Tc 99 microsulfur colloid color method using pate...
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...
BACKGROUND AND PURPOSE We hypothesized that technetium-99m-ethylene dicysteine-metronidazole (99mTc-EC-MN) localizes to brain tissue that is hypoxic but viable. This study prospectively evaluated the relationship between neurological outcome and uptake of 99mTc-EC-MN in peri-infarcted regions of the brain. METHODS Eight patients with acute ischemic stroke in the territory of the left middle c...
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...
