Objective: The clinical value of IgG anticardiolipin antibody in patients with Behçet's disease with or without vascular thrombosis was evaluated.   Methods: IgG isotype of anticardiolipin (aCL) antibody was assessed in 40 Behçet's disease (BD) patients with venous or arterial thrombosis, 40 BD patients without venous or arterial thrombosis and 80 healthy subjects as controls. The levels of IgG...

abstract background: a tumefactive lesion of central nervous system (cns) is defined as a mass-like lesion with a size greater than 2 cm in brain (magnetic resonance imaging) mri. neuroimaging may help to distinguish the nature of a tumefactive lesion and therefore can prevent an unnecessary brain biopsy. method: in this paper, we have emphasized on determining the nature of a cns tumefactive l...

introduction: recently, magnetic resonance spectroscopic imaging (mrsi), as a functional imaging method, has been used for clinical target volume definition. in this study, we used this method to define the target volume in prostate radiotherapy. material and method: in this study, we used images of 20 prostate cancer cases. mrsi and mri images were fused with ct images. then, treatment plannin...

Introduction: The magnetic resonance imaging (MRI) technique permits to monitor the development of the embryo in vivo without causing any developmental defects. Although increasing application of MRI imaging are predicted in veterinary sciences, there is little information available about MRI studies of avian embryos and their eggs. The objective of the present study was to evaluate the o...

Brachial Plexus Injury (BPI) is an uncommon complication of median sternotomy capable of causing a permanent or transitory sensitivity and/or motor function impairment in the upper limbs. During a cardiac surgery through sternotomy, for the assessment of the thoracic cage configuration and the site of mediastinal structures, a broader surgical field may be required. If the sternal retractors ar...

This study investigates the effectiveness of hundreds of texture features extracted from voxel-based dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) parametric maps for early prediction of breast cancer response to neoadjuvant chemotherapy (NAC). In total, 38 patients with breast cancer underwent DCE-MRI before (baseline) and after the first of the 6-8 NAC cycles. Quantitative ph...

To evaluate the ability of magnetic resonance imaging (MRI) to detect shoulder abnormalities 18 patients (36 shoulders) with rheumatoid arthritis (RA) and shoulder complaints were studied. Osseous abnormalities of the glenoid and humeral head were readily detected with MRI. The imaging planes used were not suitable for the evaluation of acromioclavicular joint involvement. Magnetic resonance im...

In this study, we synthesized Herceptin conjugated magnetic nanoparticles (HMNs) as an alternative probe to discover the levels of HER2 (Human epidermal growth factor receptor-2) in the surface of cells. These nanoparticles can be used by magnetic resonance imaging (MRI) (non-invasive methods) for screening the patients with HER2 positive or negative tumors. Dextran coated iron oxide nanopartic...

Diffusion-weighted magnetic resonance imaging (MRI), which involves the acquisition of a magnetic resonance signal related to the Brownian motion of water protons in tissue, has become a useful technique for assessing tumors. In this article, we review the basic concepts, imaging strategies, and body applications of diffusion-weighted MRI in detecting and monitoring cancer.
