Background: Brain tissue segmentation for delineation of 3D anatomical structures from magnetic resonance (MR) images can be used for neuro-degenerative disorders, characterizing morphological differences between subjects based on volumetric analysis of gray matter (GM), white matter (WM) and cerebrospinal fluid (CSF), but only if the obtained segmentation results are correct. Due to image arti...

In this study, images of nonuniform and uniform electric current density in conductor phantoms, which contain magnetic resonance active nuclei, are produced using Magnetic Resonance Imaging (MRI). A standard spin echo pulse sequence is used, with the addition of a bipolar current pulse. The flux density parallel to the main magnetic field, generated by the current pulse, is encoded in the phase...

Purpose This study was performed to compare the diagnostic quality of Gadofosveset-enhanced magnetic resonance venography with Gadobutrol-enhanced magnetic resonance venography and computed tomography venography for the deep veins of the lower extremities in patients with iliocaval venous pathology. Materials and methods Diagnostic capability and image quality were assessed by two independent r...

intracranial gliosis has no typical clinical signals or imaging characteristics. therefore, it can be easily misdiagnosed as neoplasm. hereby, we report a unique case of gliosis that grew outward from the surface of the brain. mri depicted its signal and enhancement pattern similar to the cerebral gray matter. the diagnosis was confirmed by pathology and immunohistochemistry. although it was di...

abstract a patient with a 3-month history of headache refractory to pain medication was admitted. the ct scan and mri showed evidence of a posterior fossa mass. this was pathologically confirmed as an extra medullary plasmacytoma (emp). he had a pathologic fracture of the left humerus 7 years ago while the radiologist was unaware at the time of diagnosis. a solitary bone plasmacytoma (sbp) was ...

intracranial lipoma is an uncommon entity. a rare type of tumor in the internal auditory canal (iac) and the cerebellopontine angle (cpa) is lipoma. there are a few case reports in the literature related to intravestibular lipoma. herein, we report a case of lipomas within the cerebellopontine angle and vestibule of the inner ear in a patient with tinnitus and dizziness. the patient was evaluat...

results compared to pre-op scores, pf, ss, and vas scores for back, buttock and leg pain had a significant mean decrease at 6, 12, 24 months post-op (p < 0.05). based on the zcq and vas scores, a success rate of 79% (27.34), 78% (30.38) and 74% (17.23) were achieved at six months, 12 months, and 24 months respectively. conclusions x-stop is a safe and effective treatment for nic that provides m...
