Comparison of Tc-99m Ethylenedicysteine (Tc-99m EC) with Tc-99m DPTA in evaluation of renal disease [Persian]

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,...

Modelo matemático y procedimiento para evaluación por complejidad de los requisitos software

Requirements Engineering provides an important basis for estimating time and effort in software development projects. Software requirements give a significant measure of product size to be developed. The University of Informatics Sciences (UCI) has an estimation method, which, in order to gain accuracy, incorporates a second estimate after the requirements phase to have more detailed technical ...

Vascular retention of Tc-99m pertechnetate and Tc-99m sestamibi, mimicking thyroid carcinoma metastases Retención vascular de 99m-Tc pertecnetato y 99m-TC sestamibi simulando metástasis de carcinoma de tiroides

Follicular thyroid carcinoma is common in regions with insufficient iodine diets and represents approximately 10-20 % of all thyroid malignancies1,2. The treatment of patients suffering from follicular thyroid carcinoma includes surgery and radioiodine therapy3. Although after definitive therapy, the survival of these patients is good, these patients need to be followed for local recurrences an...

Understanding High Tc Superconductivity ∗.

I briefly review several key issues in understanding the cuprate superconductors from the point of view of doped-Mott-insulator. Then I present an effective low-energy theory and show that the phase diagram of such a model includes an anti-ferromagnetic (AF) phase, a superconducting state, and a pseudogap phase at low doping and low temperature, consistent with the experimental one. The dual to...
