In nine patients with recent lacunar stroke who revealed multiple small lesions in x-ray computed tomography (CT) and magnetic resonance imaging (MRI), CT and MRI enhancement studies were performed on the same day employing iodinated contrast medium and gadolinium-diethylenetriaminepentaacetic acid (Gd-DTPA), respectively. In CT, the injection of contrast medium enhanced recent lesions in only ...

BACKGROUND Proton resonance frequency shift (PRFS) magnetic resonance (MR) thermometry exploits the local magnetic field changes induced by the temperature dependence of the electron screening constant of water protons. Any other local magnetic field changes will therefore translate into incorrect temperature readings and need to be considered accordingly. Here, we investigated the susceptibili...

A multicenter double-blind randomized study was designed to evaluate and compare the safety and diagnostic efficacy of gadopentetate dimeglumine (Gd-DTPA) (0.1 mmol/kg) against a saline placebo for use as an IV contrast agent for MR. The randomization code provided for a 2:1 ratio of Gd-DTPA and saline patients. Six investigators studied 88 patients with signs and symptoms of a cerebral lesion....

UNLABELLED The intracellular distribution of Auger electron-emitting radiopharmaceuticals is a determinant of cytotoxicity. However, the mechanisms by which these agents are routed through the cell are ill understood. The aim of this study was to investigate how trafficking of (111)In-labeled human epidermal growth factor ((111)In-DTPA-hEGF) relates to that of the EGF receptor (EGFR) and whethe...

Absract ✓ Objective : To develop a Convolution Neural Network (CNN) and discuss its performance in the estimation of Glomerular Fifiltration Rate (GFR) for patients with chronic kidney disease (CKD). Methods A total 112 were enrolled this study. The GFR is measured by 99mTc-DTPA renal dynamic used as standard after normalization body surface area imaging. We established CNN model verified compa...

آهن مهمترین عنصر بین عناصر کم¬مصرف برای گیاهان به ویژه در خاک¬های آهکی است. کمبود آهن در بسیاری از خاک¬های کشور گزارش شده است. تخمین سطح بحرانی عناصر غذایی در خاک تا حد زیادی متکی بر آزمون خاک است. ذرت بعد از گندم و برنج سومین گیاه استراتژیک کشور بوده و مصارف بسیار زیادی در تغذیه انسان، طیور و دام دارد. برای انجام این پژوهش 21 نمونه مرکب خاک از استان آذربایجان شرقی طوری انتخاب شدند که از دامنه ...

A new MRI-contrast agent, EB-DTPA-Gd, that has an Evans Blue analogue as a sensing unit for endothelium lesions, was designed and synthesized. The agent also has diethylenetriamine-N,N,N',N",N"-pentaacetic acid-Gd complex (Gadolinium-DTPA) units, which have been used as detection units for T1-weighted MRI. The EB-DTPA-Gd was able to recognize and adsorb to the vascular endothelium-denuded regio...

INTRODUCTION Delayed gadolinium enhanced MRI of cartilage (dGEMRIC) is a quantitative MRI method utilizing anionic contrast agent Gd-DTPA. The suggested mechanism is that the fixed charge density (FCD) of cartilage, induced by glycosaminoglycans (GAG), dictates the contrast agent distribution in cartilage via electrostatic repulsion [1]. The aim of the present study was to investigate the diffe...

Background Recent work demonstrated the feasibility of using realtime MRI to guide right heart cardiac catheterization. In order to make balloon catheters used in the procedure more conspicuous, the balloons were filled with dilute Gd-DTPA, and non-selective saturation pulses were applied along with acquisition of thick slices. The saturation pulses increased the contrast between blood and the ...

چکیده افزایش فعالیت های صنعتی طی سال های اخیر و به دنبال آن ورود انواع آلاینده های آلی و غیر آلی از جمله مس به خاک از مشکلاتی است که سلامت بشر را تهدید می کند. غلظت های بالای مس در گیاهان از رشد ممانعت به عمل آورده و فرآیند های مهم سلولی از قبیل فتوسنتز و تنفس را مختل می کند. گیاه پالایی از جمله روش های نوینی است که با انباشت عناصر سنگین در اندام هوایی گیاهان خروج این عناصر را از خاک های آلوده...
