The value of administering intravenous alteplase before endovascular treatment (EVT) for acute ischemic stroke has not been studied extensively, particularly in non-Asian populations.
Sarcopenia is emerging as an adverse prognostic factor for survival and complication risk in cancer patients. This study aims to determine the impact of sarcopenia on late toxicity a large cohort head neck squamous cell carcinoma (HNSCC) patients treated with definitive (chemo)radiotherapy ((C)RT).HNSCC (C)RT from January 2007 June 2016 were included. was assessed radiation planning computed tomography (CT) scans using skeletal muscles at level C3. The overall (OS) disease-free (DFS)...
Abstract Background Skeletal muscle depletion or sarcopenia is related to multiple adverse clinical outcome. However, frailty questionnaires are currently applied in the daily practice identify patients who potentially (un)suitable for treatment but time consuming and straining clinician. Screening with head neck cancer (HNC) could be a promising fast biomarker frailty. Our objective was quantify pre‐treatment low skeletal mass from routinely obtained computed tomography scans at level of...
OBJECTIVE Diffusion tensor imaging (DTI) has been shown to detect tumor invasion in glioblastoma patients and applied surgical planning. However, the clinical value of extent resection based on DTI is unclear. Therefore, correlation between abnormalities patients' outcome was retrospectively reviewed. METHODS A review conducted 31 with newly diagnosed supratentorial who underwent standard 5-aminolevulinic acid–aided surgery aim maximal enhancing component. All presurgical MRI, including...
Background and Purpose— Collateral circulation status at baseline is associated with functional outcome after ischemic stroke effect of endovascular treatment. We aimed to identify clinical imaging determinants that are collateral grade on computed tomography angiography in patients acute due an anterior large vessel occlusion. Methods— Patients included the MR CLEAN trial (Multicenter Randomized Clinical Trial Endovascular Treatment for Acute Ischemic Stroke Netherlands; n=500) Registry...
Abstract Background Validation of the 2016 RANO MRI scorecard for leptomeningeal metastasis failed multiple reasons. Accordingly, this joint EORTC Brain Tumor Group and effort sought to prospectively validate a revised response assessment in metastasis. Methods Coded paired cerebrospinal 20 patients with metastases from solid cancers at baseline follow-up after treatment instructions were provided via imaging platform. The Kappa coefficient was used evaluate interobserver pairwise agreement....
Purpose To determine whether regions of low apparent diffusion coefficient (ADC) with high relative cerebral blood volume (rCBV) represented elevated choline (Cho)-to–N-acetylaspartate (NAA) ratio (hereafter, Cho/NAA ratio) and their volumes correlated progression-free survival (PFS) overall (OS) in patients glioblastoma (GBM). Materials Methods This retrospective analysis was approved by the local research ethics committee. Volumetric imaging data from 43 histologically confirmed GBM...
Abstract Objectives Cross-sectional area (CSA) measurements of the neck musculature at level third cervical vertebra (C3) on CT scans are used to diagnose radiological sarcopenia, which is related multiple adverse outcomes in head and cancer (HNC) patients. Alternatively, these assessments performed with MRI, has not been validated so far. For that, objective was evaluate whether skeletal muscle mass sarcopenia can be assessed MRI scans. Methods HNC patients were included between November...
Background First-pass reperfusion (FPR) is associated with favorable outcome after endovascular treatment. It unknown whether this effect independent of patient characteristics and FPR has better outcomes compared excellent (Expanded Thrombolysis in Cerebral Infarction [eTICI] 2C-3) multiple-passes reperfusion. We aimed to evaluate the association between adjustment for patient, imaging, treatment single out contribution FPR. Methods Results was defined as eTICI 2C-3 1 pass. Multivariable...
Sarcopenia is related to late radiation-induced toxicities and worse survival in head neck cancer (HNC) patients. This study tested the hypothesis that sarcopenia improves performance of current normal tissue complication probability (NTCP) models acute toxicity HNC patients.This was a retrospective analysis prospective cohort patients treated from January 2007 December 2018 with (chemo)radiotherapy. Planning CT scans were used for evaluating skeletal muscle mass. Characteristics sarcopenic...
Writing is a sequential motor action based on sensorimotor integration in visuospatial and linguistic functional domains. To test the hypothesis of lateralized circuitry concerning spatial language components involved such action, we employed an fMRI paradigm including writing drawing with each hand. In this way, writing-related contributions dorsal ventral premotor regions hemisphere were assessed, together effects wider distributed circuitry. Given right-hemisphere dominance for right...
Abstract The challenge in the treatment of glioblastoma is failure to identify cancer invasive area outside contrast-enhancing tumour which leads high local progression rate. Our study aims its from preoperative MR radiomics. 57 newly diagnosed cerebral patients were included. All received 5-aminolevulinic acid (5-ALA) fluorescence guidance surgery and postoperative temozolomide concomitant chemoradiotherapy. Preoperative 3 T MRI data including structure MR, perfusion DTI obtained....
Optimal blood pressure (BP) targets before endovascular treatment (EVT) for acute ischemic stroke are unknown. We aimed to assess the relation between admission BP and clinical outcomes successful reperfusion after EVT.We used data from MR CLEAN (Multicenter Randomized Controlled Trial of Endovascular Treatment Acute Ischemic Stroke in Netherlands) Registry, an observational, prospective, nationwide cohort study patients with treated EVT routine practice Netherlands. Baseline systolic (SBP)...
