A multimodal neuronavigation system using metabolic images with PET and anatomical from MR is described here for glioma surgery. The efficacy of the was evaluated by comparing results that conventional navigation system, which routinely uses CT imaging as guides.Thirty-three patients cerebral underwent 36 operations aid either a or system. All were preliminarily examined l-methyl-[11C] methionine (MET) surgical planning. Seventeen performed integrating MET-PET images. other 19 based solely...
Stereotactic radiosurgery with gamma knife (GK-SRS) generally improves the focal control of brain metastases. Yet in cases recurrence at a previous radiation site, MRI is often imperfect differentiating between active tumor and injury. We have examined whether use C methionine (MET) PET will facilitate this differentiation improve outcome GK-SRS for focally recurrent metastases after prior treatment.Eighty-eight patients underwent postirradiation Thirty-four received areas manifesting high...
It is well known that intracranial lesions, which are already diagnosed on preoperative computed tomography, often expand after surgery, and the risk factors have been investigated. On other hand, we experienced cases in new were not detected found postoperative tomography. However, little about associated with such lesions. Here, investigated predictive of findings (NFs) tomography early surgery.We conducted a retrospective registry-based review 186 consecutive patients who underwent...
Objective: To evaluate the outcomes after Traumatic Brain Injury (TBI) in patients taking Antiplatelet Agents (APAs).Methods: We reviewed clinical records of 934 with TBI between 1995 and 2014. Multivariate analysis was performed to correlate patient outcome various factors, including pre-injury APA intake. Cause death compared among groups stratified according dose.Results: Increasing doses APAs were positively associated mortality rates, however, differences primarily due non-traumatic...
A right-handed Japanese man with no personal or family history of left-handedness developed severe Wernicke9s aphasia, a mild constructional disorder, and slight left hemiparesis. MRI revealed infarction in the territory right middle cerebral artery, including areas homologous to Broca9s areas. The blood flow these remained diminished even after language activation. most likely explanation is that production occurred area, while comprehension area (a dissociated aphasia).
✓ Expansion of intracerebral hematoma usually occurs in the chronic phase because repeated bleeding from preexisting vascular anomalies or exudation blood capillaries capsule. In contrast, spontaneous expanding during acute hemorrhage without rebleeding is seldom seen. Three such cases are reported, along with magnetic resonance (MR) and computerized tomography (CT) follow-up studies. The MR images CT scans demonstrated no evidence rebleeding, but revealed gradual expansion a fluid component...
Once hyperperfusion occurs after carotid endarterectomy (CEA), artificial hypotension under sedation often needs to be induced until cerebral blood flow (CBF) improves. Arterial spin-labeling magnetic resonance imaging (ASL-MRI) can noninvasively evaluate perfusion. We investigated the usefulness of ASL-MRI in a series patients with artery stenosis who underwent CEA. reviewed eight cases treated In preoperative examination, ASL-CBF had no correlation single-photon emission computed...
Objective: We reviewed the treatment results of internal carotid artery (ICA) aneurysms with a maximum diameter 10 mm or greater for future selection patients indications Pipeline Flex (Medtronic, Irvine, CA, USA).
Objective: The effects of difference in the guiding system on results stent thrombectomy were investigated.
History effects of plastic prestrain on subsequent creep behavior were studied experimentally for type 316 stainless steel at 650°C. The was first applied to thin-walled tubular specimens in the axial tensile direction, and then constant load tests carried out under various multiaxial states stress with an identical equivalent stress. Furthermore. variations resistance caused by compared those same amount prestrain. In experimental results, it shown that increase appeared differently...
