b t r t a s S g S d s b r a p a T v v p he first battle fought by drug-eluting stents (DES) was ith bare-metal stents. The 2 DES approved by the U.S. ood and Drug Administration, sirolimus drug-eluting tents (S-DES) and paclitaxel drug-eluting stents (P-DES), howed superiority in significantly reducing restenosis rates nd target lesion revascularization rates compared with are-metal stents in a...

Several reports have documented adenocarcinoma arising from endometriotic implants within cesarean section (C-S) scars on the serosal surface of the uterus; however, endometrial cancer invading the C-S scar from the uterine cavity has not been described. We report a case of a grade 1 endometrioid adenocarcinoma 'drop' lesion invading a previous C-S scar with resultant cervical stromal invasion....

tuberculosis is a major cause of morbidity and mortality worldwide. it is a chronic granulomatous disease that can affect any part of the body, including the oral cavity. oral lesions of tuberculosis, though uncommon, are seen in both the primary and secondary stages of the disease. this article presents a case of tuberculosis of the buccal mucosa, manifesting as non-healing, non-painful ulcer....

background: fine needle aspiration (fna) has led to a decrease in unnecessary surgeries for thyroid nodules. this study was designed to compare diagnostic value of fna and frozen section methods in the follicular lesions. methods: this is a cross-sectional study based on the medical records of 42 patients who were referred to surgery clinic of rasool-e-akram hospital in tehran with complaint of...

Objectives: The purpose the study was to evaluate role of diffusion weighted magnetic resonance imaging (DW-MRI) in diagnosis benign and malignant breast lesions, calculate a cut-off apparent coefficient (ADC) value explore use relative ADC (r ADC) for improving sensitivity specificity MRI cancer. Methods: This retrospective based on cohort patients who underwent dynamic contrast enhanced (DCE)...

BACKGROUND AND PURPOSE Diffusion-weighted (DW) imaging at b = 2000 s/mm(2) offers theoretical advantages over DW imaging at b = 1000 s/mm(2) for detection of hyperacute ischemic stroke. The purpose of this study was to determine whether b = 2000 images are better than b = 1000 images for detecting and estimating the extent of diffusion change within 6 hours after stroke onset. METHODS We comp...

BACKGROUND The aim of this study is to research the lesion outline and temperature field in different ways in atrial radiofrequency ablation by using finite element method. METHODS This study used the method which considered the thermal dosage to determine the boundary between viable and dead tissue, and compared to the 50 °C isotherm results in analyzing lesion outline. Besides, we used Hype...
