Following the primary traumatic injury, spinal cord tissue undergoes a series of pathobiological changes, including compromised blood-spinal cord-barrier (BSCB) integrity. These vascular changes occur over both time and space. In an experimental model of spinal cord injury (SCI), longitudinal dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI)studies were performed up to 56 days post...
Introduction: The medical imaging methods of Computed Tomography (CT), Magnetic Resonance Imaging (MRI) and Positron Emission Tomography (PET) are well established, each with their own advantages and disadvantages. There appears to be an ever increasing need to combine these modes of imaging, with the view of providing earlier diagnosis of disease, improved treatment planning and better patient...
the treatment of in completely formed pulpless teeth has presented considrable problems. these teeth have wide open apexes and the walls of the root canal diverge toward the apical tissues. mechanical preparation cannot be done in the normal manner beacause of the large initial size and the taper of apical part of the canal , a mechanical stop cannot be produced at the apex of the canal and , t...
مقایسه یافته‌های بالینی و نتایج روش جراحی باز در درمان فتق اولیه با عود دیسک بین مهره‌ای لومبوساکرال
Background and Aim: Despite improving therapeutic methods of lumbosacral disc herniation, open surgery is still the conventional method. This study was aimed to investigate the recurrence rate and risk factors of lumbar disc herniation after open surgery and comparison of clinical outcomes of second surgery with the first surgery. Materials and Methods: This prospective descriptive study was pe...

BACKGROUND The impact of magnetic resonance imaging (MRI) on pacemakers is potentially hazardous. We present clinical results from a novel MRI conditional pacing system with the capability to switch automatically to asynchronous mode in the presence of a strong magnetic field. AIMS The IKONE (Assessment of the MRI solution: KORA 100™ and Beflex™ pacing leads system) study is an open-label, pr...
با توجه به تفکیک پذیری فضایی خوب دستگاه mri می توان انتظار داشت که بتوان از آن در تشخیص نوعی گرفتگی در عضله خون رسان قلب که در تعیین شاخصهای کمی آن نقش مهمی دارند مانند ] کسر جهشی (ef)، ضخامت دیواره، تزریق وریدی میوکاردیال [استفاده کرد. به همین دلیل یکی از این پارامترها به عنوان خواسته ی این پروژه با فرض وجود بیمار به تعداد مناسب مد نظر بود. با mri می توان در جهات فوقانی-تحتانی (اگزیال)، چپ-ر...
