CONTEXT The differential cortical function obtained by Tc-99m EC is comparable to that of Tc-99m DMSA. However, identification of scars on Tc-99m EC images needs to be studied. AIMS The aim of the study is to evaluate role of Tc-99m EC for detection of scarring and differential cortical function by comparing with Tc-99m DMSA. SETTINGS AND DESIGN Prospective observational study of recurrent ...

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...

The aim of this study was the investigation of absorbed dose to the kidneys, spleen, and liver during technetium-99 m ethylene dicysteine and technetium-99 m diethylenetriaminepentaacetic acid ((99m)Tc-EC and (99m)Tc-DTPA) kidney scan. Patients who had been prepared for the kidney scan, were divided into two groups (Groups 1 and 2). The first group (Group 1) and the second group (Group 2) recei...

tc-99m-ec is a new renal radiopharmaceutical introduced as an alternative for tc-99m mag3. twenty-three normal volunteers and patients in different .stages of renal disease were evaluated with te-99m ec and tc-99m dtpa. the mean initial uptake of ec was significantly higher as compared to dtpa. there was a high correlation between rectangular and hand-drawn rols for kidney and background, 0.96 ...

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...

Objective- To consider the use of renal scintigraphic evaluation of kidney function in Persian cat and make a comparison between 99mTechnetium ethylenedicysteine and 99mTechnetium diethylenetriaminepentaacetic in renal scintigraphy. Design- Descriptive study Animals- 6 male healthy adult Persian cats - no clinical sign of renal disorders and prior to presentation. Proce...

A 10-year-old boy with a history of bloody discoloration of urine following recent appendectomy was referred to our department for urinary leakage/fistula evaluation. A renal Technetium-99m-L,L-ethylenedicysteine (99mTc-EC) scintigraphy was performed. After injection of radiotracer, a focus of activity appeared in the supralateral part of the right kidney which was confirmed as accum...

The technetium-99m complex of the L,L-ethylenedicysteine diethylester (EC), of the brain imaging agent, was reported as a good choice for replacement of the renal nuclear medicines like OIH radiopharmaceutical. This present research work studies the structural, electronic and spectral properties of the EC compound and its complex with technetium-99m radionuclide from theoretical insight. All co...

Technetium-99m-ethylene-l-l-dicysteine ((99m)Tc-EC) is an agent with a potential for renal imaging. It is reported that EC uses the same tubular transporter system as ortho-hippurate (OIH) and mercaptoacetyltriglycine (MAG3) and that this agent has good imaging properties and higher renal clearance than MAG3. In this study we used (99m)Tc-EC to compare different washout parameters in renal tran...
