زمینه و هدف:�تعیین سطح ضایعه در بیماران مبتلا به هرنی دیسک کمری بویژه اگر مهره ترانزیشنال وجود داشته باشد دشوار است، MRI یکی از روش هایی است که بطور گسترده قبل از عمل بکار گرفته می شود، با این وجود ساکرالیزاسیون یا لومباریزاسیون ممکن است منجر به تشخیص نادرست گردد. هدف از این مطالعه، بررسی ضریب توافق بین نتایج MRI و جراحی با یافته های رادیوگرافی پس از عمل در بیماران دچار فتق دیسک کمری است.روش کا...
MRI is one of the most powerful techniques to study the internal structure of the body. MRI image quality is affected by various noises. Noises in MRI are usually thermal and mainly due to the motion of charged particles in the coil. Noise in MRI images also cause a limitation in the study of visual images as well as computer analysis of the images. In this paper, first, it is proved that proba...
Background Transfusion-induced iron overload leads to many complications in patients with β-thalassemia major. This study aimed to compare the level of iron stored in the liver and heart measured by MRI T2 * with ferritin levels in these patients. Materials and Methods This study was done on 52 patients with β-thalassemia major aged 7 to 29 years. Serum ferritin level was checked and heart and ...
Background: Polymer gel dosimeters combined with magnetic resonance imaging (MRI) can be used for dose verification of advanced radiation therapy techniques. However, the uncertainty of dose map measured by gel dosimeter should be known. The purpose of this study is to investigate the uncertainty related to calibration curve and MRI protocol for MAGIC (Methacrylic and Ascorbic acid in Gelatin I...
Background: Carbon monoxide (CO) poisoning may lead to hypoxic/anoxic injury and eventually ischemic encephalopathy. Magnetic resonance imaging (MRI) has a well-recognized role in assessment of the severity of brain damage caused by CO poisoning. In this study, we aimed to present and analyze the structural abnormalities in the brain MRI and especially in diffusion weighted MRI (DWI) images in ...
