Background: The characteristic clinical presentation of glomus tumors and the low negative predictive value of themagnetic resonance imaging (MRI) raise the question whether MRI improves their management. Therefore, this studyaimed to investigate whether MRI improved the management of glomus tumors.Methods: In total, 87 patients with a histologically confirmed glomus tumor wer...

introduction: scintigraphy has been considered as a useful tool in the assessment of meniscal tears. our objective was to assess the accuracy of single photon emission tomography (spect), using mri as the gold standard, in the diagnosis of meniscal tears. materials and methods: between january 2003 and february 2005, 45 patients were studied with spect and mri. results: the respective sensitivi...

Detection of brain tissues using magnetic resonance imaging (MRI) is an active and challenging research area in computational neuroscience. Brain MRI artifacts lead to an uncertainty in pixel values. Therefore, brain MRI segmentation is a complicated concern which is tackled by a novel data fusion approach. The proposed algorithm has two main steps. In the first step the brain MRI is divided to...

conclusion both techniques provided quantitatively consistent results of in vivo velocity vector fields in right internal carotid artery (rca). pc mri represented a good estimation of main flow patterns inside the vasculature, which seems to be acceptable for clinical use. however, limitations of each technique should be considered while interpreting results. subjects and methods mr imaging was...

in this paper, the boundary-based estimation of pressure distribution in the cardiovascular system is investigated using two dimensional flow images. the conventional methods of non-invasive estimation of pressure distribution in the cardiovascular flow domain use the differential form of governing equations. this study evaluates the advantages of using the integral form of the equations in the...

conclusions ultrasound is recommended as the first choice when fb is located within the superficial soft tissues with no bone around it. in case of penetration of fb into deeper tissues or beneath bone, ct or cbct are recommended. otherwise, considering lower dose, cbct is preferred over ct. we can use mri if the fb is not ferromagnetic. however, ct is the first choice in emergency situations b...

conclusion due to the significant improvement in the treatment of early stage of hcc compared to the previous decade, we suggest a fast, non-invasive, more accurate, but more expensive method (haste, op/ip t1w sequences mri combined with dwi) rather than us for the screening of hcc in liver cirrhosis. results combination of limited sequences mri and dwi had the highest accuracy (94.79%) followe...

background dynamic contrast-enhanced magnetic resonance imaging (dce - mri) has been widely used in the management of breast cancer, and its diagnostic value in breast imaging has been demonstrated. there have only been a few reports regarding the usefulness of pre-contrast imaging. knowledge about clinically significant findings of preoperative, pre-contrast t1 and t2 mr images will allow more...
