the aim of this review is focusing on the most important safety issues in cardiovascular mri (magnetic resonance imaging) which are categorized as: 1-safety items in patients who referred for stress cardiac mr studies. 2-safety consideration that we must know when a patient with cardiovascular devices referred for any (cardiovascular or non-cardiovascular) mri with focus on new protocols accord...

Introduction: Multiple sclerosis (MS) is a demyelinating disease of the central nervous system (CNS), affecting mostly young people at a mean age of 30 years. Magnetic resonance imaging (MRI) is one of the most specific and sensitive methods in diagnosing and detecting the evolution of multiple sclerosis disease. But it does not have the ability to differentiate between distinct histopathologic...

Objective(s): Systemic lupus erythematosus (SLE) is an autoimmune disease with a wide range of clinical manifestations. Cognitive dysfunction is one of the manifestations that could present prior to the emergence of any other neuropsychiatric involvements in SLE. Cognitive dysfunction is a subtle condition occurring with ahigh frequency. However, there is no data on the correlation of cognitive...

Background: There are various methods to read out responses of a polymer-gel dosimeter, among which the Magnetic Resonance Imaging (MRI) technique is the most common one. Optimizing imaging protocols can have significant effect on the sensitivity and the dose resolution of polymer gel dosimeters. This study has investigated the effects of the number of echoes (NOE) and the echo time spacing (ES...

    Background: Magnetic resonance imaging (MRI) has long been considered a perfect imaging study for evaluation of shoulder pathologies despite occasional discrepancies between MR reports and arthroscopic findings. In this study we aim to evaluate impact of imaging center as an indicator of image quality on accuracy of MRI reports in diagnosis of rotator cuff tendon pathologies. Methods: We re...

Magnetic resonance imaging (MRI) uses a constant magnetic field and radio waves, a non-invasive method for examining tissues, organs and the skeletal system. Advantages and disadvantages of MRI are not fully understood; however, it has been commonly used in the diagnosis of skeleton and bone diseases (such as disk and spinal disorders, joint disorders (arthritis), bone tumours and tissues...

abstract deep seated cavernous angioma (ca) is a very rare entity, those occurring in the hypothalamus are still less common. we present a case of a 52-year-old man who presented with behavior and memory disturbance attacks. he had a ca of the hypothalamus as revealed by magnetic resonance imaging (mri). we will discuss the role and importance of imaging in such scenario and also the differenti...

fundal gallbladder abnormalities result from broad spectrum of pathologic that most of them have no pathological significance and normally causes no symptoms. conversely, early incidental detection of malignant lesions is important because symptomatic lesions are often incurable. so use proper imaging to differentiate between them is important. although ultrasound has been the choice screen met...

Introduction: The primary and definitive diagnosis of meningioma is based on histological assessment; however, employing imaging methods, like Magnetic Resonance Imaging (MRI) is very helpful to describe lesion’s characteristics. Accordingly, we decided to study the effect of imaging factors, like MRI data on the volume of hemorrhage (estimated blood loss) during meningioma surgery. Methods: T...

objective(s): the study objective was to assess the diagnostic performance of positron emission tomography (pet) for gliomas using the novel tracer 18f-fluciclovine (anti-[18f]facbc) and to evaluate the safety of this tracer in patients with clinically suspected gliomas.methods: anti-[18f]facbc was administered to 40 patients with clinically suspected high- or low-grade gliomas, followed by pet...
