BACKGROUND In previous studies, the authors found that patients with spontaneous confabulation differ from those with nonconfabulating amnesia by 1) temporal context confusion (TCC) in memory based on an inability to suppress intrusions of currently irrelevant memory traces into ongoing thinking; and 2) lesions involving the orbitofrontal cortex, basal(More)
BACKGROUND There is limited information about predictors of outcome and recurrence of ischaemic stroke affecting young adults. OBJECTIVE To assess the predictive value of the presenting characteristics for both outcome and recurrence in young stroke victims. METHODS Clinical and radiological data for 203 patients aged 16 to 45 years were collected(More)
OBJECTIVE To define predictors of recanalisation and clinical outcome of patients with acute basilar artery occlusions treated with local intra-arterial thrombolysis (IAT). METHODS Vascular risk factors, severity of the neurological deficit graded by the National Institutes of Health stroke scale (NIHSS), and radiological findings were recorded at(More)
The aim of this study was to evaluate the impact of preoperative devascularization of spinal metastases in relation to the preembolization tumor vascularization degree and in relation to the intraoperative blood loss. Twenty-four patients underwent preoperative transarterial embolization of hypervascular spinal metastases. Each tumor was assigned a(More)
BACKGROUND Chronic neck pain after whiplash injury is caused by cervical zygapophysial joints in 50% of patients. Diagnostic blocks of nerves supplying the joints are performed using fluoroscopy. The authors' hypothesis was that the third occipital nerve can be visualized and blocked with use of an ultrasound-guided technique. METHODS In 14 volunteers,(More)
BACKGROUND AND PURPOSE Acute ischemic stroke with mild or rapidly improving symptoms is expected to result in good functional outcome, whether treated or not. Therefore, thrombolysis with its potential risks does not seem to be justified in such patients. However, recent studies indicate that the outcome is not invariably benign. METHODS We analyzed(More)
BACKGROUND AND PURPOSE The purpose of this study was to analyze the immediate and long-term angiographic and clinical results of endovascular treatment of posterior circulation aneurysms with special regard to technical development. MATERIALS Between 1993 and 2003, 46 patients with 47 aneurysms of the posterior circulation were referred to our institution(More)
BACKGROUND Transsphenoidal surgery guided by intraoperative MRI (iMRI) is related to higher rates of tumour resection. The influence of iMRI on endocrinological outcome is still unclear. This study evaluates the endocrinological outcome of iMRI-guided transsphenoidal surgery. METHODS A series of 60 patients operated by iMRI-guidance for inactive adenomas(More)
OBJECT Sellar lesions with suprasellar extension may cause loss of visual acuity and visual field damage due to compression of the optic chiasm. Using intraoperative MR (iMR) imaging to detect symptomatic lesion remnants adjacent to the optic chiasm (that may be resected in the same procedure) may positively affect the functional outcome of patients with(More)
The hippocampal formation (HF) of healthy control subjects and schizophrenic patients was examined using an MRI experiment that implements sequences for relaxometry and magnetization transfer (MT) quantification. In addition to the semi-quantitative magnetization transfer ratio (MTR), all of the observable properties of the binary spin bath model were(More)
