VIPR-SSFP was added 1.5-T MR performed on 95 patients (52 men, 43 women; average age, 41.6 years) who...

Sarcoidosis is a systemic granulomatous disorder associated with hypergammaglobulinemia and the presence of autoantibodies. The specific antigens initiating inflammation in sarcoidosis are unknown, there no test available to diagnose sarcoidosis. To discover novel antigens, we developed high-throughput T7 phage display library derived from cDNA identified numerous clones differentiating other respiratory diseases. After clone sequencing homology search, two epitopes (cofilin μ chain A) that...

The purpose of this study was to examine prevalence trends serious extra-articular manifestations (EAMs) in a data set representing both hospitalized and ambulatory patients with RA.This retrospective cohort used serial cross-sectional the EAMs RA from 1985 2006 across United States (US) Veteran's Health Administration system. Serious included rheumatoid carditis, lung disease, FS pooled EAM rates previously reported vasculitis as queried by ICD-9 searches. Statistical analysis employed...

The purpose of this study was to compare the accuracy 3-T MRI with that 1.5-T knee in diagnosis meniscal tear and analyze causes diagnostic error.We reviewed medical records original interpretations 100 consecutive patients who underwent determine diagnoses tear. Knee arthroscopy reference standard. We retrospectively all errors cause errors.At arthroscopy, 109 medial 77 lateral tears were identified 200 patients. With two abnormal MR images indicating a tear, sensitivity specificity for...

To evaluate the clinical usefulness of volumetric analysis at nonenhanced computed tomography (CT) as sole method with which to follow up endovascular abdominal aortic aneurysm repair (EVAR) and identify endoleaks causing more than 2% increase from previous volume determination.The study had institutional review board approval. Images were reviewed retrospectively in a HIPAA-compliant manner for 230 CT studies 70 patients (11 women, 59 men; mean age, 74 years) who underwent EVAR. The...

The purpose of this study was to compare multiple imaging planes and two pulse sequences for detection arthroscopically proven labral tears.From March 2004 through June 2007, acetabular tear diagnosed at hip arthroscopy 189 patients. Preoperative MR arthrography the affected performed on 144 patients our institution. These arthrograms were retrospectively reviewed by a musculoskeletal fellow radiologists. used coronal T1-weighted with fat saturation, T2-weighted sagittal axial oblique...

Purpose To determine whether the mammographic density of noncalcified solid breast masses is associated with malignancy and to measure agreement between prospective retrospective assessment. Materials Methods The institutional review board approved this study waived informed consent. Three hundred forty-eight consecutive in 328 women who underwent image-guided or surgical biopsy October 2005 December 2007 were included. All 348 biopsy-proved randomized assigned a radiologist was blinded...

To compare the diagnostic performance of iterative decomposition water and fat with echo asymmetry least-squares estimation (IDEAL) gradient-recalled acquisition in steady-state (GRASS) imaging a routine magnetic resonance (MR) protocol for evaluating knee cartilage at 3.0 T patients by using arthroscopy as reference standard.This prospective Health Insurance Portability Accountability Act-compliant study was performed waiver informed consent from institutional review board.

Slow or stagnant flow is a hemodynamic feature that has been linked to the risk of aneurysm rupture.To assess potential value ratio volume an area its ostium (VOR) as indicator intra-aneurysmal slow and, thus, in turn, rupture.Using sample defined from internal databases, retrospective analysis size, aspect (AR), and VOR was performed on series 155 consecutive aneurysms having undergone 3-dimensional digital subtraction angiography part their evaluation. Measurements were obtained studies...

To compare the diagnostic performance of iterative decomposition water and fat with echo asymmetry least-squares estimation (IDEAL)-spoiled gradient-recalled (SPGR) that standard magnetic resonance (MR) arthrography sequences for detecting grading cartilage lesions within hip joint during MR arthrography.Following institutional review board approval, 67 consecutive arthrograms were retrospectively reviewed independently by three musculoskeletal radiologists one fellow. IDEAL-SPGR images...

Abstract Objective To examine trends in the prevalence of rheumatoid vasculitis a national US population comprising both hospitalized and ambulatory patients with arthritis (RA). Methods In this serial cross‐sectional study, we analyzed data on spanning 22 years (1985–2006) 10 (1997–2006), respectively, to determine vasculitis, as defined by International Classification Diseases, Ninth Revision. Our search encompassed collected predominantly male study during million hospitalizations...

In this study, a reliability-based calibration of live-load factors for bridge design specific to the state Michigan was conducted. Two years high-frequency weigh-in-motion (WIM) data from 20 representative statewide sites were analyzed, and load effects generated spans 6 122 m (20 400 ft), considering simple continuous moments shears, single-lane two-lane effects. Seventy-five-year statistics maximum live then estimated with probabilistic projection. Bridge girders considered included...

The purpose of our study is to identify and quantify the association between high breast mass density malignancy using inductive logic programming (ILP) conditional probabilities, validate this in an independent dataset. We ran ILP algorithm on 62,219 mammographic abnormalities. set Aleph system generate 10,000 rules per malignant finding with a recall >5% precision >25%. reported best rule for each finding.

BACKGROUND Impaired microvascular perfusion in the obese patient has been linked to chronic adverse health consequences. The impact on acute illnesses including trauma, sepsis, and hemorrhagic shock (HS) is uncertain. Studies have shown that endothelial glycocalyx vascular derangements are causally abnormalities. Trauma HS also associated with impaired which injury dysfunction sentinel events. We postulate obesity may consequences of barrier. This was studied vivo a biomimetic model using...
