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...

objective(s): the aim of this work was to prepare and characterize magnetic nanoparticles (mnps) as theranostic system to act simultaneously as drug carrier and mri contrast agent. chitosan-coated mnps (cmnps) were prepared and loaded with silymarin. silymarin-loaded cmnps were characterized with various techniques and their potential as mri contrast agent was also evaluated. materials and meth...

Background: To compare the value of physical examination, transvaginal sonography (TVS), rectal endoscopic sonography (RES), and magnetic resonance imaging (MRI) for the assessment of different locations of deep infiltrating endometriosis (DIE). Materials and Methods: Ninety-two consecutive patients with clinical evidence of pelvic endometriosis. Physical examination, TVS, RES, and MRI, perform...

To investigate the effects of magnetic resonance image (MRI) exposure on CNS development, we examined the effects of neonatal exposure of rats to a MRI magnetic field on their performance in the Morris water maze. After birth, all litters were randomly divided into an MRI-scanning group (experimental group) comprised of 7 mother rats and their offspring, and a control group, which consisted of ...

Reliable early assessment of breast cancer response to neoadjuvant therapy (NAT) would provide considerable benefit to patient care and ongoing research efforts, and demand for accurate and noninvasive early-response biomarkers is likely to increase. Response assessment techniques derived from quantitative magnetic resonance imaging (MRI) hold great potential for integration into treatment algo...

This paper reviews some of the major and most recent advances in nanoscale-magnetic resonance imaging (nano-MRI) for personalized medicine (PM). Nano-MRI may drastically expand the capabilities of the traditional magnetic resonance images (MRI), down to the nanometer scale and possibly, in the near future, at the atomic scale. Nano-MRI is potentially able to observe structures which cannot be s...

Advances in the management of transfusion dependent thalassemic patients have improved the survival of these patients. The most important consequence of repeated and frequent transfusions is iron accumulation in vital organs. The magnetic resonance imaging (MRI) is a non-invasive and valid technique for the estimation of iron stores. Despite multiple studies about cardiac and liver MRI T2*, the...

Objective: This study investigates the possible magnetic resonance imaging (MRI) findings in patients with cervical trauma having a normal level of consciousness and normal CT reports. These patients have tenderness or an uncomfortable feeling in the traumatized area as well.Methods: In this cross-sectional anterograde study, cases were selected among patients referred to the emergency de...

Accurate segmentation of brain tumor plays a key role in the diagnosis of brain tumor. Preset and precise diagnosis of Magnetic Resonance Imaging (MRI) brain tumor is enormously significant for medical analysis. During the last years many methods have been proposed. In this research, a novel fuzzy approach has been proposed to classify a given MRI brain image as normal or cancer label and the i...
