<h3>BACKGROUND AND PURPOSE:</h3> Unlike in Europe and Japan, guidelines or recommendations from specialized radiological societies on workflow management adaptive intervention to reduce error rates are currently lacking the United States. This study of neuroradiologic reads at a large US academic medical center, which may hopefully contribute this discussion, found direct relationship between rate shift volume. <h3>MATERIALS METHODS:</h3> CT MR imaging reports our institution's...
BACKGROUND: Modifiable risk factors play a central role in the development and course of neurodegenerative disorders later life, including dementias. Although past research has focused on independent associations modifiable factors, cardiovascular disease using Framingham score, physical activity, dietary quality, body mass index, sleep, neurodegeneration, impact all 5 simultaneously multimodal model not been studied. We examined an overall combined with white matter injury, recognized...
BACKGROUND. Numerous studies have explored factors associated with diagnostic errors in neuroradiology; however, large-scale multivariable analyses are lacking. OBJECTIVE. The purpose of this study was to evaluate associations interpretation time, shift volume, care setting, day week, and trainee participation by neuroradiologists at a large academic medical center. METHODS. This retrospective case-control using tertiary-care center's neuroradiology quality assurance database evaluated CT...
Abstract The Hispanic/Latino population is one of the largest and most diverse ethnoracial groups in United States at high risk for dementia. We examined cognitive constructs associations with subsequent hippocampal volume (HV) white matter hyperintensity (WMHV). Participants were from Hispanic Community Health Study/Study Latinos–Magnetic Resonance Imaging Study ( n = 2029). confirmatory factor analysis longitudinal invariance using neurocognitive scores Visits 1 (2008–2011) 2 (2014–2018)...
<h3>BACKGROUND AND PURPOSE:</h3> Unilateral decreased/nonvisualization of a transverse dural sinus on MRV poses diagnostic dilemma when gadolinium administration is contraindicated. We determined the frequency unilateral and performance pregadolinium MR imaging sequences in diagnosing thrombosis presence phase-contrast MRV. <h3>MATERIALS METHODS:</h3> conducted retrospective review consecutive 3D (VENC, 30 cm/s) routine brain (noncontrast sagittal T1, axial T2, FLAIR, DWI, GRE,...
Background For patients with oral cavity squamous cell carcinoma (OCSCC) without evidence of nodal metastasis (cN0) on pre-operative evaluation, there are no clear guidelines who should undergo elective neck dissection (END) versus clinical surveillance. Objective To identify CT imaging characteristics sub-centimeter lymph nodes that would help predict the likelihood metastases pathology. Methods Retrospective review cN0 OCSCC at a tertiary academic medical center was performed. Inclusion...
To develop an image fusion technique using elliptical centric contrast-enhanced (CE) MR angiography (MRA) and three-dimensional (3D) time-of-flight (TOF) acquisitions for radiosurgery treatment planning of arteriovenous malformations (AVMs).CE 3D-TOF angiograms with disparate in-plane fields view (FOVs) were acquired, followed by k-space reformatting to provide equal voxel dimensions. Spatial domain addition was performed a third, fused data volume. distortion evaluated on MRA phantom...
Diagnostic errors affect 2%-8% of neuroradiology studies, resulting in significant potential morbidity and mortality. This retrospective analysis a large database at single tertiary academic institution focuses on diagnostic misses cerebrovascular pathology suggests error-reduction strategies.CT MR imaging reports from consecutive spanning 2015-2020 were searched for attending physicians pathology. Data collected missed findings, study types, interpretation settings. Errors categorized as...
Biphenotypic sinonasal sarcomas were initially described in 2012 and introduced to the 4th edition of World Health Organization (WHO) classification head neck tumors as a new disease entity. We present first comprehensive case description combining radiologic, surgical pathologic findings biphenotypic sarcoma young patient who presented with nonspecific obstructive symptoms, left orbital pain proptosis. While there is no distinct radiologic imaging finding differentiate from other...
Medical errors result in significant mortality and morbidity. The purpose of this study is to analyze skull-base at a single tertiary institution, identify common anatomic sites errors, offer strategies reduce region.A Neuroradiology Quality Assurance Database radiologic was searched for attending physician computer tomography magnetic resonance imaging pathology from 2014 2020. Data were limited CT MRI reports. Errors separated into four subcategories (tumor, trauma, vascular, congenital)...
OBJECTIVE. Accurate diagnosis of spinal cord compression (SCC) or cauda equina (CEC) is important in the emergency setting so management decisions may be made promptly. The purpose this study to evaluate performance on-call radiology residents interpreting total spine MRI studies for detection SCC CEC. MATERIALS AND METHODS. On-call residents' preliminary interpretation performed over a period two and half years were evaluated. Agreements disagreements determined (defined as severe stenosis...
We study the $\mathbb{Z}_2$-homology groups of orbit space $X_n = G_{n,2}/T^n$ for canonical action compact torus $T^n$ on a complex Grassmann manifold $G_{n,2}$. Our starting point is model $(U_n, p_n)$ $X_n$ constructed by Buchstaber and Terzi\'c (2020), where $U_n \Delta _{n,2}\times \mathcal{F}_{n}$ hypersimplex $\Delta_{n,2}$ an universal parameters $\mathcal{F}_{n}$ defined in (2019), (2020). It proved (2021) that diffeomorphic to moduli $\mathcal{M}_{0,n}$ stable $n$-pointed genus...
ABSTRACT Background and Purpose There is limited literature on the prevalence of incidental brain MRI findings in Hispanic/Latino population, despite their increased vascular disease undertreatment chronic conditions. The purpose our study was to determine clinically relevant examinations obtained as a part Study Latinos–Investigation NeuroCognitive Aging (SOL‐INCA‐MRI) study. Methods Brain were 1389 participants SOL‐INCA‐MRI study, cross‐sectional ancillary Hispanic Community Health Study,...
Intraoperative magnetic resonance imaging (iMRI) is a powerful tool used to verify maximal safe resection of gliomas. However, unsuspected new or incidental findings can present difficult clinical scenarios. Here we case large supratentorial glioma where new, bilateral cerebellar hemispheric enhancement was noted on iMRI. A 52-year-old male with intra-axial mass spanning the right temporal and parietal lobes underwent craniotomy for tumor utilizing Imaging displayed remote, enhancement. Upon...
Purpose To reduce the total scan time of multiple postlabeling delay (multi‐PLD) pseudo‐continuous arterial spin labeling (pCASL) by developing a hierarchically structured 3D convolutional neural network (H‐CNN) that estimates transit (ATT) and cerebral blow flow (CBF) maps from reduced number PLDs as well averages. Methods A 48 subjects (38 females 10 males), aged 56–80 years, compromising training group (n = 45) validation 3) underwent MRI including multi‐PLD pCASL. We proposed an H‐CNN to...
