Measurements of diagnostic examination performance and correlation analysis using microvascular leakage, cerebral blood volume, and blood flow derived from 3T dynamic susceptibility-weighted contrast-enhanced perfusion MR imaging in glial tumor gradingNeuroradiology - Tập 53 - Trang 435-447 - 2010

To assess the diagnostic accuracy of microvascular leakage (MVL), cerebral blood volume (CBV) and blood flow (CBF) values derived from dynamic susceptibility-weighted contrast-enhanced perfusion MR imaging (DSC-MR imaging) for grading of cerebral glial tumors, and to estimate the correlation between vascular permeability/perfusion parameters and tumor grades. A prospective study of 79 patients wit...... hiện toàn bộ
Intracranial gas on CT after Cardiopulmonary resuscitation: 4 casesNeuroradiology - Tập 40 - Trang 154-157 - 1998
M. Imanishi, A. Nishimura, H. Tabuse, S. Miyamoto, T. Sakaki, S. Iwasaki
We report four patients in whom gas was seen in the head on CT shortly after cardiopulmonary resuscitation. The gas was in the posterior cranial fossa, presumably within veins, or in the cavernous sinus. The cause of the cardiac arrest was myocardial infarction in three patients and hanging in one. All had peripheral or central venous lines. The mechanism by which gas appeared in the intracranial...... hiện toàn bộ
Proton magnetic resonance spectroscopy of neurocytoma outside the ventricular region – case report and review of the literatureNeuroradiology - Tập 44 - Trang 230-234 - 2014

Central neurocytoma is classically considered as an intraventricular benign tumour, largely based on data from small retrospective series and single case reports. We report on a 16-year-old girl who suffered from a large parietooccipital tumour that was diagnosed histologically as central neurocytoma. The features of CT, MRI and proton MR spectroscopy studies are discussed. This is the first repo...... hiện toàn bộ
MR with surface coils in the follow-up after endoscopic laser resection for glottic squamous cell carcinomaNeuroradiology - Tập 55 - Trang 225-232 - 2012

This study focuses on the feasibility and diagnostic accuracy of MR of the larynx performed with surface coils after endoscopic laser resection (ELR) for glottic cancer. Thirty-one MR examinations of the larynx performed with surface coils on average 12 months after ELR were retrospectively reviewed. Image quality was assessed for each acquired sequence (score 1–3). All the postoperative focal les...... hiện toàn bộ
Cortical venous disease severity in MELAS syndrome correlates with brain lesion developmentNeuroradiology - Tập 59 - Trang 813-818 - 2017
M. T. Whitehead, M. Wien, B. Lee, N. Bass, A. Gropman
MELAS syndrome is a mitochondrial disorder typified by recurrent stroke-like episodes, seizures, and progressive brain injury. Abnormal mitochondria have been found in arterial walls implicating a vasculogenic etiology. We have observed abnormal cortical vein T2/FLAIR signal in MELAS patients, potentially representing wall thickening and sluggish flow. We sought to examine the relationship of hype...... hiện toàn bộ
Comparing extended versus standard time window for thrombectomy: caseload, patient characteristics, treatment rates and outcomes—a prospective single-centre studyNeuroradiology - Tập 63 - Trang 603-607 - 2020

New guidelines recommend thrombectomy up to 24 h in selected patients; however, the workload and benefit of extending time window are not known. We conducted a prospective single-centre study to determine the caseload, imaging and interventional need of extended time window. All consecutive ischemic stroke patients within 24 h from onset in an 11-month period were included. Thrombectomy eligibilit...... hiện toàn bộ
