the aim of radiation therapy treatment planning is to achieve an optimal balance between delivering a high dose to target volume and a low dose to healthy tissues. in order to refrain any complications resulting from the dose to the surrounding normal organs, the role of treatment plan has been critically evaluated in term of how large the volume or mass of normal tissues exposed in the radiati...
background: the right ventricular (rv) dyssynchrony has not been studied extensively and the existing literature has established the effect of cardiac resynchronization therapy (crt) on the left ventricular (lv) dyssynchrony, but there is a dearth of data on the effect of crt on the forgotten ventricle . we sought to evaluate the presence of mechanical right ventricular dyssynchrony in patients...
Background: Cardiac resynchronization therapy (CRT) has proved as an efficient treatment in patients with end stage Heart failure. Previous studies showed the beneficial long term effects of CRT on the severity of mitral regurgitation (MR). The aim of this study was to evaluate acute effects of CRT on severity of MR. Methods: This study was a double blind randomized trial performed from 1387 t...
background: breast cancer is the most common type of cancer in women demanding time and accurate diagnosis to take remedial measures to treat. objective: comparing the diagnostic capability of the computer regulation thermography (crt), as a novel and safe dignostic procedure, with common clinical examination and imaging methods including sonography and mammography for diagnosing breast cancer ...

چکیده مقدمه: ناهم‌زمانی انقباض بطن چپ در نارسایی قلبی، بویژه در آنهایی که کمپلکس QRS پهن دارند، بسیار شایع است. درمان هم‌زمان‌سازی قلبی (CRT)در نارسایی قلبی پیشرفته، نتایج امیدوارکننده‌ای داشته است. هدف:مقایسه عملکرد بطن چپ پیش و پس از درمان هم‌زمان‌سازی قلبی در نارسایی قلبی مواد و روش‌ها: در یک مطالعه مقطعی، 65 مورد پی‌درپی نارسایی قلبی که برای CRT برنامه‌ریزی شده بودند وارد مطالعه شده و اکوکا...
background: the emergence and spread of chloroquine resistant plasmodium falciparum in the world stimulated some investigators to consider different aspects of chloroquine resistance in human and rodent plasmodia . using animal plasmodia , particularly primate and rodent plasmodia can be useful model for human plasmodia studies. in this study we have tried to consider and compare the sequence ...
سرطان پستان شایع ترین بیماری در بین انواع بیماری های سرطانی در زنان است. در این مطالعه روش تشخیصی دمانگاری کامپیوتری (crt) همراه با روش های ارزیابی بالینی، تصویربرداری سونوگرافی و ماموگرافی در مقابل نتایج پاتولوژی بیماران مبتلا به سرطان پستان مورد بررسی قرار گرفته است. 44 بیمار از میان 97 فرد مراجعه کننده در مرکز تحقیقات سرطان بیمارستان شهدای تجریش که دارای شرایط ورود به مطالعه بودند، انتخاب ش...
Introduction: We aimed to dosimetrically compare three-dimensional conformal radiotherapy (3D-CRT) and volumetric modulated arc therapy (VMAT) in terms of planning target volume (PTV) coverage, organ at risk (OAR) sparing, and conformity index (CI). Material and Methods: Planning data of 26 high grade glioma (HGG) patients were used. Prescrib...
