To estimate cumulative radiation exposure and lifetime attributable risk (LAR) of radiation-induced cancer from computed tomographic (CT) scanning adult patients at a tertiary care academic medical center.This HIPAA-compliant study was approved by the institutional review board with waiver informed consent. The cohort comprised 31,462 who underwent diagnostic CT in 2007 had undergone 190,712 examinations over prior 22 years. Each patient's estimated summing typical effective doses,...
To estimate the correlation between negative appendectomy rate (NAR) and of preoperative computed tomography (CT) in patients suspected having acute appendicitis who presented to emergency department during an 18-year period.This retrospective institutional review board-approved, HIPAA-compliant study was performed a 719-bed tertiary care adult teaching hospital with 58,000 annual visits. The authors obtained waiver informed consent used medical records system compare 2003 2007 those 1990...
To determine the effect of evidence-based clinical decision support (CDS) on use and yield computed tomographic (CT) pulmonary angiography for acute embolism (PE) in emergency department (ED).Institutional review board approval was obtained this HIPAA-compliant study, which performed between October 1, 2003, September 30, 2009, at a 793-bed quaternary care institution with 60,000 annual ED visits. Use (number examinations per 1000 visits) (percentage positive PE) CT were compared before...
The purpose of our study was to define a conservative estimate the number patients undergoing repeat or multiple emergency department CT studies and quantify their cumulative radiation doses lifetime attributable risk developing cancer.We identified all at tertiary care adult academic medical center with least three visits within 1-year period that included neck, chest, abdomen, pelvis. For this cohort, we diagnostic over previous 7.7 years. We calculated by summing typical effective...
Traumatic elbow injuries are commonly encountered in the emergency department setting, but their complexity and clinical significance often go unrecognized at initial evaluation. Initial imaging patients with trauma should not only help identify major that require immediate intervention also allow detection of other, more subtle may lead to instability or poor functional outcomes if appropriate treatment is delayed. Awareness these be improved by a better-developed intuitive understanding...
Use of computed tomography (CT) in medicine comes with the responsibility its appropriate (wise) and safe (gentle) application to obtain required diagnostic information lowest possible dose radiation. CT provides useful that may not be available other imaging modalities many clinical situations children adults. Inappropriate or excessive use should avoided, especially if can obtained an accurate time-efficient manner require a lower radiation dose, non-radiation-based such as ultrasonography...
Frailty is associated with poor surgical outcomes in elderly patients but difficult to measure the emergency setting. Sarcopenia, or loss of lean muscle mass, a surrogate for frailty and can be measured using cross-sectional imaging. We sought determine impact sarcopenia on 1-year mortality after abdominal surgery patients.Sarcopenia was assessed 70 years older who underwent at single hospital from 2006 2011. Average bilateral psoas area L3, normalized height (Total Psoas Index [TPI]),...
Purpose: To retrospectively evaluate the technical quality of and visibility biliary tree pancreatic duct on magnetic resonance (MR) cholangiopancreatographic (MRCP) images obtained with a single-breath-hold three-dimensional (3D) fast-recovery fast spin-echo (FRFSE) sequence in comparison conventional two-dimensional (2D) single-shot (SSFSE) thin-section thick-slab sequences. Materials Methods: Institutional review board approval was obtained; informed consent not required for this...
The objective of our study was to assess radiology utilization trends for emergency department (ED) patients from 1993 through 2012.For this retrospective study, we reviewed at a 793-bed quaternary care academic medical center January 1, 1993, December 31, 2012, during which time the number ED patient visits increased approximately 48,000 61,000, and determined imaging studies by modality (radiography, sonography, CT, MRI, other) associated relative value units (RVUs). We used linear...
Treating trauma patients with displaced pelvic fractures requires a multidisciplinary approach at designated center to reduce morbidity and mortality. Immediate recognition of ring disruption determination stability are critical components in the evaluation such patients. Stability is achieved by ability osseoligamentous structures pelvis withstand physiologic stresses without abnormal deformation. The supporting ligaments, including posterior anterior sacroiliac, iliolumbar, sacrospinous,...
The Thoracolumbar Injury Classification and Severity Score (TLICS) is a scoring classification system developed by the Spine Trauma Study Group in response to recognition that previous systems have limited prognostic value generally do not suggest treatment pathways. TLICS provides spine injury severity score based on three components: morphology, integrity of posterior ligamentous complex (PLC), neurologic status patient. A numerical calculated for each category, with lower point assigned...
Imaging utilization in emergency departments (EDs) has increased significantly. More than half of the 1.2 million patients with mild traumatic brain injury (MTBI) presenting to US EDs receive head CT. While evidence-based guidelines can help clinicians decide whether obtain CT these patients, adoption been highly variable. Promulgation imaging efficiency by National Quality Forum intensified need for performance reporting, but measuring adherence currently requires labor-intensive and...
