Abstract Purpose While radiotherapy (RT) for head and neck cancer (HNC) has made recent strides, RT-induced vasculitis continues to adversely affect long-term patient outcomes. Guidelines managing this complication remain scarce, supporting the need a sensitive imaging modality in post-treatment evaluations. In review, we discuss current literature regarding 18 F-fluorodeoxyglucose positron emi...

روش‌های مختلفی برای زمان­‌سنجی امواج مشابه و با تحریک یکسان ارایه شده است که توجه به شرایط موج می‌­توان بهترین گزینه را انتخاب کرد. لذا هدف ما یافتن روش زمان‌سنجی جهت خروجی از حسگر UFSD زیرا می­‌خواستیم این حسگرها آشکارسازی پروتون‌ها در سیستم پروتون درمانی برای­ درمان ­تومورهای سرطانی استفاده کنیم. راستا مقایسه مختلف مثل تفکیک‌کننده کسر ثابت (CFD)، همبستگی متقابل(CC) زمان بیش آستانه (TOT)با داد...

Objective(s): The present study aimed to evaluate the role of pretherapeutic 18fluorine-fluorodeoxyglucose positron emission tomographycomputed tomography (18F-FDG PET-CT) and maximum standardized uptake value (SUVmax) in guiding the treatment strategy and predicting the prognosis of esophageal carcinoma, using the survival data of thepatients.Methods: The present retrospective, cohort study wa...

Introduction: All of the Imaging modalities have advantages and disadvantages alone. So if we want to have the best and perfect image, combining these modalities produces something we desired. PET-MR images consist of morphologic and metabolic data. MRI and PET provide high spatial and contrast resolution and high sensitivity and molecular information respectively. Hybrid PET-...

Introduction:The accuracy of positron emission tomography with computed tomography (PET/CT), positron emission mammography (PEM), and breast specific-gamma imaging (BSGI) in diagnosing breast cancer has never been systematically assessed, the present systematic review was aimed to address this issue.  Methods:PubMed, Scopus and EMBASE were searched for st...

Introduction: Accurate staging plays an important role in management of patients with prostate cancer especially in high-risk group. Today, [68Ga]Ga-PSMA-11 PET/CT should be considered as the preferred imaging tool for treatment planning and initial staging of the disease. Methods: A total number of 628 patients with prostate cancer referred to...

ابتلای یکی از اعضای خانواده به بیماری مزمن، بر روابط، نقش‌ها، سلسله مراتب و به‌طور کلی سیستم تأثیر می‌گذارد را برای مدیریت سازگاری با شرایط جدید، چالش‌هایی مواجه می‌کند. هدف این مرور ادبیات پژوهشی، شناسایی مسائلی است که در مزمن اعضا، آن رو‌به‌روست. بدین منظور، بررسی نظام‌مند مقالات چاپ‌شده زبان فارسی یا انگلیسی مجلات داخلی خارجی سال 201۴ (دی ۱۳۹۲) تاکنون، پایگاه‌های SID، Magiran، Google Scholar...

Introduction: Due to the large number of PET systems available in the market, it is not very easy to decide about the scanner of choice. Conducting a research in order to compare all different PET scanners is very time consuming and expensive and practically impossible. However, such comparison may be conducted using PET simulators. In this study, the performance of 6 different PET scanne...

Plastic (Polyethylene Terephthalate, PET) is now used as packaging material for a whole range of consumer products in addition to carbonated beverages. Although plastics are very useful product, but the disposal of these wastes has become a problem and is of great concern, particularly in our country. One of the solutions to the disposal of plastic wastes is recycling it...

Surface modified electrospun polyester (PET) nanofibers with cyclodextrin polymer (CDP) were produced (PET/CDP). CDP formation onto electrospun PET nanofibers was achieved by polymerization between citric acid (CTR, crosslinking agent) and cyclodextrin (CD). Three different types of native CD (α-CD, β-CD and γ-CD) were used to form CDP. Water-insoluble crosslinked CDP coating was permanently ad...
