We report on the accuracy of electrode placement under robotic assistance planning utilizing a novel high-resolution magnetic resonance imaging (MRI)-based imaging modality.Sixteen pediatric patients between February 2014 and October 2017 underwent SEEG exploration for epileptogenic zone localization. The authors evaluated whether MRI enhanced with a blood pool ferumoxytol (Fe) contrast agent (Fe-MRI) can be used for surveillance of residual or recurrent AVMs.A retrospective cohort was assembled of children with an established AVM diagnosis who underwent surveillance by both DSA and 3-T Fe-MRI from 2014 to 2016. Deep Learning for Pediatric Posterior Fossa Tumor Detection and Classification: A Multi-Institutional Study. Two raters independently calculated normalized tumor blood flow (TBF) on postprocessed ASL images using ROI analysis. Borderline statistical significance was found between DVA size and presence of PWI abnormality (P = .046). We further discuss machine-learning challenges and data opportunities to advance radiomic studies. Conclusion MRI measurements of susceptibility, R2*, and R2' (R2* - R2) obtained after ferumoxytol administration correlate with iron-containing macrophage concentration, and this shows their potential as quantitative imaging markers of macrophages in malignant gliomas. Mean normalized TBF for the group with tumor blush and the group without tumor blush group was 4.7 1.1 and 1.5 1.1, respectively, for rater 1 and 4.9 5.3 and 1.5 1.1, respectively, for rater 2.

Coverage », Getting Clinical and Arterial Spin Labeling Brain MRI Features of Transitional Venous Anomalies. Two readers assessed ASL signal location relative to the vascular lesion on MRI and, if available, the presence of arteriovenous shunting on DSA.Thirty patients with DVA-like lesions with increased ASL signal were identified. DWI and PWI alone had a 95.9% sensitivity and a 98.4% specificity for accurate endovascular triage. Integration of this technology into neurosurgical practice is still in its nascence, however. Two readers also evaluated full-Fourier variable refocusing flip angle single-shot FSE against T2-FSE for brain lesion detectability in 38 children.Variable refocusing flip angle single-shot FSE sequences showed more motion artifacts (P View details for DOI 10.3174/ajnr.A6616 View details for PubMedID 32586967, View details for Web of Science ID 000509478700102. Intracranial hemorrhage is common and is caused by diverse pathology, including trauma, hypertension, cerebral amyloid angiopathy, hemorrhagic conversion of ischemic infarction, cerebral aneurysms, cerebral arteriovenous malformations, dural arteriovenous fistula, vasculitis, and venous sinus thrombosis, among other causes. In previous clinical trials, antiangiogenic therapies such as bevacizumab did not show efficacy in patients with newly diagnosed glioblastoma (GBM). Tumefactive demyelination associated with developmental venous anomaly: Report of two cases. Median overall survival was 21.3 months (95% Confidence Interval (CI) 15.9, NA) with a progression-free survival of 14.5 months (95% CI 11.8, NA). Elizabeth Tong MD. Yeom, K. W., Holdsworth, S.

The apparent diffusion coefficient (ADC) map from Echo1 was used to validate presence of true pathology. Comparison of Readout-Segmented Echo-Planar Imaging (EPI) and Single-Shot EPI in Clinical Application of Diffusion-Weighted Imaging of the Pediatric Brain. OBJECTIVE Patients with brain arteriovenous malformations (AVMs) often require repeat imaging with MRI or MR angiography (MRA), CT angiography (CTA), and digital subtraction angiography (DSA). The sensitivity and specificity for detecting residual AVMs using Fe-SPGR were 100% and 100%, and using ASL they were 72% and 100%, respectively. For both readers, the sensitivity for lesion detection was high for all image types but highest for overlapping CUBE MIP and CUBE (0.93-0.97).This study suggests that the use of overlapping CUBE MIP or nonoverlapping CUBE MIP for the detection of brain metastases can reduce interpretation time without sacrificing sensitivity, though the contrast-to-noise ratio of lesions is highest for overlapping CUBE MIP. Patients who received modern systemic therapy for LM had decreased hazard of death (hazard ratio [HR], 0.24; P= .007).In this retrospective, single-institution analysis, median survival with LM was higher compared with historical experience. Mean overall survival after LM diagnosis was 6 months (95% CI, 3-12). Practical Pearl: Use of MRI to Differentiate Pseudo-subarachnoid Hemorrhage from True Subarachnoid Hemorrhage. Ma, M., Chen, J.

Brain MRI in these patients have revealed various findings including ischemia, hemorrhage, inflammation, and demyelination. We assembled a multidisciplinary team and retrospectively reviewed all functional MR imaging examinations performed at our institution from January 2013 to August 2015. The mean diameter for involved vessels was 0.9826 0.1008 mm.We believe this novel sequence allows better identification of superficial and deeper subcortical vessels compared to conventional T1-weighted gadolinium-enhanced MRI. For ASL, signal in the DVA, surrounding parenchyma, or associated draining vein was recorded. A., Wang, J., Edwards, M. S., Grant, G. A., Cheshier, S. H., Yeom, K. W. Macrophage Exclusion after Radiation Therapy (MERT): A First in Human Phase I/II Trial using a CXCR4 Inhibitor in Glioblastoma. Altered cerebral perfusion in children with Langerhans cell histiocytosis after chemotherapy. He completed his radiology residency training at Practical Pearl: Use of MRI to Differentiate Pseudo-subarachnoid Hemorrhage from True Subarachnoid Hemorrhage. Electrode placement accuracy was determined by analyzing postoperative CT scans laid over preoperative virtual electrode trajectory paths. A computational framework was developed to extract MR imaging-based radiomic features from tumor segmentations, and we tested 2 predictive models: a double 10-fold cross-validation using a combined dataset consisting of all 3 patient cohorts and a 3-dataset cross-validation, in which training was performed on 2 cohorts and testing was performed on the third independent cohort. The ideal imaging modality provides excellent vascular visualization without incurring added risks, such as radiation exposure. We conducted a phase I/II study to determine the safety and efficacy of Macrophage Exclusion after Radiation Therapy (MERT) using the reversible CXCR4 inhibitor plerixafor in newly diagnosed glioblastoma patients.We enrolled 9 patients to the phase I study and an additional 20 patients to phase II using a modified toxicity probability interval (mTPI) design. This rare diagnosis carries an extremely poor prognosis, with death usually occurring within 1 year. For the subgroup, the mean interval between the first and last ferumoxytol administration was 14 months 8 (range, 1-25 months). To investigate the frequency and characteristics of developmental venous anomaly (DVA)-associated perfusion abnormalities on arterial spin labeling (ASL) and bolus perfusion-weighted imaging (PWI) and discuss their potential causes.We reviewed brain MR reports to identify all DVAs reported on studies performed between 2009 and 2012. Here we use a cross-disciplinary approach to highlight studies in radiomics. Multivariable regression analysis was used for statistical analysis.A total of 18 patients [brainstem (15) and thalamus/basal ganglia (3); median follow-up: 270 d] were identified over 2 yr. The primary outcome measure was accurate ET triage. Statistical analyses were performed using SAS Enterprise Guide, version 4.3.LM was identified in 30 patients. With the independent 3-dataset cross-validation strategy, select radiomic features were predictive of sonic hedgehog (area under the curve = 0.70-0.73) and group 4 (area under the curve = 0.76-0.80) medulloblastoma.This study provides proof-of-concept results for the application of radiomic and machine learning approaches to a multi-institutional dataset for the prediction of medulloblastoma subgroups. Data sets were evaluated with a prototype of now commercially available software (Syngo Circulation I; Siemens Medical Solutions, Erlangen, Germany), which automatically segments the blood volume in the left ventricle after the user defines the mitral valve plane and any point within the ventricle. Newer MRI sequences have been developed to increase the conspicuity of detecting enhancing metastases. Children with intracranial arteriovenous malformations (AVMs) undergo digital DSA for lesion surveillance following their initial diagnosis. Ultrasmall superparamagnetic iron oxide nanoparticles are an emerging tool that can add clinically useful information due to their distinct physiochemical features and biodistribution, while having a good safety profile. Yet, in both MCI and AD, we know little about what site of stimulation would be ideal for improving cognitive function. View details for DOI 10.1016/j.clinimag.2020.08.029. Ependymoma prediction was the least accurate. Zhang, M., Telischak, N. A., Fischbein, N. J., Steinberg, G. K., Marks, M., Zaharchuk, G., Heit, J. J., Iv, M. Magnetic resonance perfusion image features uncover an angiogenic subgroup of glioblastoma patients with poor survival and better response to antiangiogenic treatment.

D., Kapadia, K. B., Zaharchuk, G. Deep Learning for Pediatric Posterior Fossa Tumor Detection and Classification: A Multi-Institutional Study. Huang, Y., Singer, T. G., Iv, M., Lanzman, B., Nair, S., Stadler, J. On PWI, the majority of DVAs demonstrated abnormalities (108/136, 79%), typically increased CBF, CBV, MTT, and Tmax. DWI and PWI images alone were anonymized and scored for cerebral infarction, LVO presence and LVO location, DWI-PWI mismatch, and ET candidacy. Previous clinical trials testing whether cholinesterase inhibitors can slow the rate of progression from MCI to AD dementia have yielded disappointing results. The primary efficacy measure is the California Verbal Learning Test-II (CVLT-II), assessed 1week after intervention. Plerixafor was continuously infused intravenously via PICC line for four consecutive weeks beginning at day 35 of conventional treatment with concurrent chemo-radiation. MR imaging is key to tumor detection, diagnosis, and therapy guidance. Interrater agreement was very good ( = .81-1.0, P < .001).A DVA-like lesion with increased ASL signal likely represents a TVA with arteriovenous shunting. Tumor histology served as ground truth except for diffuse midline glioma of the pons, which was primarily diagnosed by MR imaging. Association of developmental venous anomalies with perfusion abnormalities on arterial spin labeling and bolus perfusion-weighted imaging. MR Imaging-Based Radiomic Signatures of Distinct Molecular Subgroups of Medulloblastoma. The mean age was 58 years. A., Huang, Y., Lee, E. H., Iv, M., Moseley, M. E., Holdsworth, S. J., Yeom, K. W. Variable Refocusing Flip Angle Single-Shot Imaging for Sedation-Free Fast Brain MRI. Mild Cognitive Impairment (MCI) carries a high risk of progression to Alzheimer's disease (AD) dementia. A Bland-Altman plot revealed a slight mean difference between EF measurements on CT and echocardiography, with all differences falling within two standard deviations of the mean in the setting of wide limits of agreement. Stereoelectroencephalography (SEEG) is a powerful intracranial diagnostic tool that requires accurate imaging for proper electrode trajectory planning to ensure efficacy and maximize patient safety. The total number of metastases identified was not significantly different across the image types.

Calter - Deputy University Librarian Email [email protected] Tel 650-723-5553 Bio ACADEMIC APPOINTMENTS • Vice Provost, Academic Council, Stanford University Libraries In 27 female and seven male patients (mean age, 62.8 years), mean normalized TBF for meningiomas with tumor blush on DSA was significantly higher than those without tumor blush (p < 0.001). Two sites in each tumor were selected for intraoperative sampling on the basis of the degree of ferumoxytol-induced signal change. A preliminary report is generated with use of software for a DXA unit and a customized template that includes numeric and qualitative assessments of osteoporosis as well as data from prior studies if available. This supplement sketches how a reductive form of analysis emerged in Descartes’s development of analytic geometry, and elaborates onthe way in which decompositional conceptions of analysis came to the fore in the early modern period, as outlined in §4of the main document. As a result, we reduced our routine scheduling time for functional MR imaging from 2 hours to 1 hour, improving patient comfort and satisfaction as well as saving time for additional potential MR imaging acquisitions. Diffusion tensor imaging (DTI) is an advanced magnetic resonance imaging technique that is capable of providing rich information on the brain's neuroanatomic connectome. Interrater agreement was good to very good for all image groups ( = 0.77-1.0, p < 0.001). There were 157 overall intersection + near-miss events. Theruvath, A.
