The objective of our study was to determine the value diffusion-weighted imaging (DWI) and conventional MRI (non-DWI sequences) in differentiating benign portal vein thrombus (PVT) from malignant PVT cirrhotic patients.A retrospective search department radiology's database examinations performed October 2006 through December 2010 for "portal thrombosis" "cirrhosis" "hepatocellular cancer" performed. Patients who underwent diagnostic DWI had shown be rapidly (< 3 months) increasing size...
The object of this study was to determine the specific CT findings injury profile in penetrating brain (PBI) that are risk factors related intracranial arterial injuries.The authors retrospectively evaluated admission head CTs and accompanying digital subtraction angiography (DSA) studies from patients with trauma period between January 2005 December 2012. Two reviewed images presence or absence 30 variables quantified selected variables. characteristics without injuries were compared using...
Object The authors conducted a study to compare the sensitivity and specificity of helical CT angiography (CTA) digital subtraction (DSA) in detecting intracranial arterial injuries after penetrating traumatic brain injury (PTBI). Methods In retrospective evaluation 48 sets angiograms from 45 consecutive patients with PTBI, 3 readers unaware DSA findings reviewed CTA images determine presence or absence injuries. A fourth reader all disagreements decided among interpretations. Sensitivity,...
INTRODUCTION: Diffuse Axonal Injury (DAI) is graded on MRI using the Adams Classification, which has limited prognostic utility. Machine Learning (ML) a promising tool to detect more granular lesions predict clinical outcomes. METHODS: The study included patients diagnosed with DAI who were hospitalized between July 2012 and March 2022 without midline shift or surgical intervention. ML was used segment SWI images correlated anatomic parcellation maps identify lesion location, number, volume....
<h3>BACKGROUND AND PURPOSE:</h3> Abnormal signal intensity of the optic nerve due to diffusion restriction may be seen in traumatic neuropathy. In addition evaluating hyperintensity on diffusion-weighted imaging, we compared group differences ADC values between injured and uninjured contralateral identified relation measured admission visual acuity. <h3>MATERIALS METHODS:</h3> We retrospectively evaluated 29 patients with neuropathy who underwent MR imaging DWI. Uninjured nerves were used as...
Purpose To develop and test a computed tomography (CT)-based predictive model for major arterial injury after blunt pelvic ring disruptions that incorporates semiautomated hematoma volume quantification. Materials Methods A multivariable logistic regression was developed in patients with who underwent phase abdominopelvic CT before angiography from 2008 to 2013. Arterial at requiring transarterial embolization (TAE) served as the outcome. Areas under receiver operating characteristic (ROC)...
To present a method that automatically detects, subtypes, and locates acute or subacute intracranial hemorrhage (ICH) on noncontrast CT (NCCT) head scans; generates detection confidence scores to identify high-confidence data subsets with higher accuracy; improves radiology worklist prioritization. Such may enable clinicians better use artificial intelligence (AI) tools. This retrospective study included 46 057 studies from seven "internal" centers for development (training, architecture...
Abstract The INSPIRE randomized clinical trial demonstrated that a high protein diet (HPRO) combined with neuromuscular electrical stimulation (NMES) attenuates muscle atrophy and may improve outcomes after aneurysmal subarachnoid hemorrhage We sought to identify specific metabolites mediating these effects. Blood samples were collected from subjects on admission prior randomization either standard of care (SOC; N = 12) or HPRO + NMES (N at 7 days. Untargeted metabolomics performed for each...
To determine the specific facial computed tomographic (CT) findings that can be used to predict traumatic optic neuropathy (TON) in patients with blunt craniofacial trauma and propose a scoring system identify at highest risk of TON.This study was compliant HIPAA, permission obtained from institutional review board. Facial CT examination 637 consecutive history were evaluated retrospectively. The following variables evaluated: midfacial fractures, extraconal hematoma, intraconal hematoma...

Decompression of the injured spinal cord confers neuroprotection. Compared with timing surgery, verification surgical decompression is understudied.To compare judgment cervical using real-time intraoperative ultrasound (IOUS) following laminectomy postoperative MRI and CT myelography.Fifty-one patients were retrospectively reviewed. Completeness was evaluated by IOUS compared (47 cases) myelography (4 cases).Five cases (9.8%) underwent additional after initial evaluation to yield a final...
Using diffusion tensor imaging, we evaluated the directional diffusivities of optic nerve in patients with traumatic neuropathy (TON).Our study consisted 12 unilateral TON, 6 severe brain injury (comparison group A), and normal conventional magnetic resonance imaging B). The contralateral TON also was C). Two trauma radiologists, blinded to clinical diagnosis, independently obtained diffusivities. intraorbital divided into anterior posterior segments evaluate intersegmental differences...
<h3>BACKGROUND AND PURPOSE:</h3> Extravasation of iodinated contrast into subdural space following contrast-enhanced radiographic studies results in hyperdense effusions, which can be mistaken as acute hematomas on follow-up noncontrast head CTs. Our aim was to identify the factors associated with contrast-enhancing effusion, characterize diffusion and washout kinetics iodine enhancing assess utility dual-energy CT differentiating effusion from hematoma. <h3>MATERIALS METHODS:</h3> We...
This prospective longitudinal study compares the ability of conventional and diffusion tensor imaging (DTI) parameters made at cervical spinal cord injury (CSCI) site to predict long-term neurological functional outcomes. Twenty patients with CSCI, follow-up 6 or 12 months, 15 control volunteers were included. Conventional magnetic resonance (MRI) DTI measured on admission studies. Stepwise regression analysis was performed find relevant (normalized values, MRI measurements, hemorrhagic...
Background Grading of pelvic fracture instability is challenging in patients with binders. Dual-energy CT (DECT) and cinematic rendering can provide ancillary information regarding osteoligamentous integrity, but the utility these tools remains unknown. Purpose To assess added diagnostic value DECT rendering, respect to single-energy (SECT), for discriminating any translational Materials Methods In this retrospective analysis, consecutive adult (age ≥18 years) were stabilized binders scanned...
The purposes of this study were to assess the diagnostic performance 40- and 64-MDCT angiography with digital subtraction as reference standard in detection arterial injuries patients at high risk after penetrating neck trauma perform a separate analysis external carotid artery.In retrospective evaluation 53 sets angiograms from 51 injury, three reviewers unaware angiographic findings reviewed CT (CTA) images discern presence or absence injuries. Sensitivity specificity CTA calculated per...
