Multiparametric magnetic resonance imaging has been increasingly used for detection, localization and staging of prostate cancer over the last years. It combines high-resolution T2 weighted-imaging and at least two functional techniques, which include dynamic contrast-enhanced magnetic resonance imaging, diffusion-weighted imaging, and magnetic resonance imaging spectroscopy. Although the combi...

In the patient with cancer, magnetic resonance imaging is increasingly used as a diagnostic tool for disease detection, lesion characterization, as well as the assessment of treatment response. Although non-contrast T1-weighted and T2-weighted imaging, together with low molecular weight extracellular gadolinium contrast-enhanced T1-weighted magnetic resonance imaging remain the cornerstone for ...

BACKGROUND The value of magnetic resonance imaging of the brain in the diagnosis of iatrogenic cases of Creutzfeldt-Jakob disease has been questioned. OBJECTIVE To illustrate the value of magnetic resonance imaging of the brain in the diagnosis of iatrogenic Creutzfeldt-Jakob disease. METHODS Case report. RESULTS A patient with a history of 3 corneal transplantations exhibited the alien h...

background studies show that a large proportion of healthcare offered may be inappropriate or unnecessary. magnetic resonance imaging (mri) is a new and expensive diagnostic technology which has been increasingly used all over the world. moreover, this trend has been more rapidly increasing in iran. low back pain is a common disorder all over the world and mri technique is one of the several wa...

conclusions ti is an important parameter to consider in the relationship between si and nanoparticle concentrations. an increase in ti leads to a decrease in the range of linearity. results the results indicate that si depended on the concentration of nanoparticles and ti. in addition, si increased by increasing the tis ranging from 200 to 400 ms for all studied concentrations. the linear relat...

introduction as functional magnetic resonance imaging (fmri) is too expensive and time consuming, its frequent implementation is difficult. the aim of this study is to evaluate repeatability of detecting visual cortex activity in fmri. materials and methods in this study, 15 normal volunteers (10 female, 5 male; mean age±sd: 24.7±3.8 years) attended. functional magnetic resonance images were ob...

background: back pain is a common patients' complaint, and its etiology is important because of different potential treatment approaches (based on causes). for a better diagnosis, magnetic resonance imaging (mri) is widely used in clinical settings that may result in inappropriate requests. this study aims to evaluate the appropriateness of the lumbosacral mri requests in patients with back pai...

background and aims. although salivary gland tumors are not very common, early diagnosis and treatment is crucial because of their proximity to vital organs, and therefore, determining the efficacy of new imaging procedures becomes important. this study aimed to evaluate the efficacy of magnetic resonance imaging (mri) and color doppler ultrasonography parameters in the diagnosis and differenti...
