OBJECTIVE To assess the relationship between asymptomatic carotid stenosis, neuropsychological test performance, and silent MRI lesions. METHODS Performance on several neuropsychological tests was compared in 189 subjects with ultrasound-assessed carotid stenosis and 201 control subjects without carotid stenosis, recruited from a population health study.(More)
BACKGROUND AND PURPOSE Tumors of the cranial nerve sheath constitute 5% to 10% of all intracranial neoplasms, yet few articles have described their CT and MR characteristics. We report the imaging findings in a relatively large series of schwannomas of the jugular foramen, contrasting them with other disease entities, especially vestibular schwannomas and(More)
OBJECTIVE The present study was conducted to validate S-100 protein as a marker of brain damage after minor head injury. METHODS We studied 50 patients with minor head injuries and Glasgow Coma Scale scores of 13 to 15 in whom computed tomographic scans of the brain revealed no abnormalities. Serum levels of S-100 protein were measured at admittance and(More)
BACKGROUND AND PURPOSE The safety and efficiency of the dual-layer Woven EndoBridge (WEB) device has already been published. However, this international multicenter study sought to evaluate the safety of single-layer devices, which are the newest generation of the WEB intrasaccular flow-disrupter family. They have been designed to offer smaller-sized(More)
Central nervous system involvement was evaluated in 36 patients with systemic lupus erythematosus (SLE) using cerebral computed tomography (CT), electroencephalography (EEG), and a neuropsychological test battery. The purpose was to investigate whether brain dysfunction as assessed by comprehensive neuropsychological investigation is associated with(More)
Cognitive dysfunction is found in a considerable proportion of patients with systemic lupus erythematosus (SLE). SPECT provides an estimate of regional cerebral blood flow (rCBF) which has been claimed to be sensitive to detect brain involvement in SLE. It is, however, uncertain if these perfusion defects are related to cognitive dysfunction. In the present(More)
The association between postoperative nerve root signs and outcome was investigated in 54 out of one hundred patients operated on by lumbar microdiscectomy in a prospective cohort study with one year follow up. The patients were classified as failures or successes at the 12 month follow up according to a clinical overall score. All the 14 failures were(More)
Gliosarcoma is a highly malignant brain tumor consisting of both a glioblastoma and a mesenchymal component. The latter typically resembles fibrosarcoma, but differentiation patterns resembling osteosarcoma, chondrosarcoma, angiosarcoma and rhabdomyosarcoma have also been described. Molecular-genetic studies have shown that both glioblastoma and the(More)
OBJECTIVE To assess the cognitive impairment and the association between neuropsychological measures and neuroimaging 1 year after aneurysmal subarachnoid hemorrhage (SAH). METHOD Forty-two patients were examined clinically according to Glasgow Outcome Scale (GOS). Computed tomography (CT), single photon emission computed tomography (SPECT) and(More)
PURPOSE An autostereoscopic display with image quality comparable to ordinary 2D displays has recently been developed. The purpose of our study was to evaluate whether the visualization of static 3D models from intracranial time-of-flight (TOF) MR angiography (MRA) was improved by this display. METHODS Maximum Intensity Projection (MIP) and Volume(More)
