Infarcts Due to Large Vessel Occlusions Continue to Grow Despite Near-Complete Reperfusion After Endovascular Treatment.

Background And Purpose: Infarcts in acute ischemic stroke (AIS) patients may continue to grow even after reperfusion, due to mechanisms such as microvascular obstruction and reperfusion injury. We investigated whether and how much infarcts grow in AIS patients after near-complete (expanded Thrombolysis in Cerebral Infarction [eTICI] 2c/3) reperfusion following endovascular treatment (EVT), and to assess the association of post-reperfusion infarct growth with clinical outcomes.

Methods: Data are from a single-center retrospective observational cohort study that included AIS patients undergoing EVT with near-complete reperfusion who received diffusion-weighted magnetic resonance imaging (MRI) within 2 hours post-EVT and 24 hours after EVT.

Parotid Warthin's tumor: novel MR imaging score as diagnostic indicator.

Objectives: Despite known characteristic radiologic and clinical features, differentiation between Warthin's tumor (WT) and other parotid tumors remains challenging. The purpose of this study was to more precisely assess the MR imaging features of WT and to develop a scoring system combining the most specific characteristics.

Methods: A total of 208 patients with parotid gland tumors and presurgical MRI were included.

Imaging features of vertebral artery fenestration.

Purpose: Vertebral artery fenestration (VAF) is a rare congenital vascular anomaly which has been associated with intracranial aneurysm. VAF can share some similar imaging features with vertebral artery dissection (VAD), which may confound diagnosis of the latter on CT and MR angiography. The purpose of this investigation is to assess the prevalence of VAF, evaluate its association with other vascular anomalies, and identify imaging features to help in distinguishing VAF and VAD.

Comparing the short-term cost-effectiveness of epidural steroid injections and medical management alone for discogenic lumbar radiculopathy.

Objective: Epidural steroid injections (ESIs) are a commonly used treatment strategy for low back pain and lumbar radiculopathy. However, their cost-effectiveness and ability to mediate long-term quality of life (QOL) improvements is debated. We sought to analyze the cost-effectiveness of lumbar epidural steroid injections (ESIs) compared to medical management alone for patients with lumbar radiculopathy and low back pain.

Musculoskeletal Radiology Reports: Overlooked or Valuable?

The electronic medical record (EMR) can reveal preferences of clinicians regarding imaging services. We sought to evaluate viewing habits for reports and images of musculoskeletal (MSK) studies by ordering clinicians. We hypothesized that MSK reports are important to clinical management, especially for advanced imaging modalities.

Quality of life changes after lumbar decompression in patients with tandem spinal stenosis.

Objective: Tandem spinal stenosis (TSS) is a degenerative spinal condition characterized by spinal canal narrowing at 2 or more distinct spinal levels. It is an aging-related condition that is likely to increase as the population ages, but which remains poorly described in the literature. Here we sought to determine the impact of primary lumbar decompression on quality-of-life (QOL) outcomes in patients with symptomatic TSS.

Cost and quality of life outcome analysis of postoperative infections after posterior lumbar decompression and fusion.

Surgical site infections (SSI) following spine procedures are serious and costly complications that may reduce patient quality of life (QOL). Deep SSIs may also extend hospitalizations and require surgical debridement or antibiotic therapy, increasing costs to both patients and the healthcare system. Here we sought to evaluate the effect of deep SSI on care cost and QOL outcomes in patients undergoing posterior lumbar decompression and fusion.

Cost-Effectiveness of Cervical Epidural Steroid Injections: A 3-Month Pilot Study.

Study Design: Retrospective cohort.

Objectives: There are conflicting reports on the short- and long-term quality of life (QOL) outcomes and cost-effectiveness of cervical epidural steroid injections (ESIs). The present study analyzes the cost-effectiveness analysis of ESIs versus conservative management for patients with radiculopathy or neck pain in the short term.

Factors Impacting False Positive Recall in Screening Mammography.

Rationale And Objectives: Our objective was to identify factors impacting false positive recalls in screening mammography.

Materials And Methods: We retrospectively reviewed our screening mammography database from August 31, 2015 to September 30, 2016, including full field digital mammograms (FFDM) and digital breast tomosynthesis (DBT) mammograms. False positive (FP) exams were defined as Breast Imaging-Reporting and Data System (BI-RADS) 1 or 2 assessments at diagnostic imaging with 1 year cancer-free follow-up, Breast Imaging-Reporting and Data System 3 assessment at diagnostic imaging with 2 years cancer free follow-up, or biopsy with benign pathology.

"Worst Headache of Life" in a Migraineur: Marginal Value of Emergency Department CT Scanning.

Purpose: The ACR Appropriateness Criteria recommend performing noncontrast head CT (NCCT) for patients with sudden severe headache ("worst headache of life" [WHOL] or "thunderclap headache" [TCH]). The aim of this study was to assess the value of NCCT scanning in patients with known migraine histories and WHOL or TCH. The hypothesis was that there would be little utility in performing emergency department (ED) NCCT scans in migraineurs without other red flags, even if they had WHOL or TCH.

Spine Surgeon Treatment Variability: The Impact on Costs.

Study Design: Cross-sectional analysis.

Objectives: Given the lack of strong evidence/guidelines on appropriate treatment for lumbar spine disease, substantial variability exists among surgical treatments utilized, which is associated with differences in costs to treat a given pathology. Our goal was to investigate the variability in costs among spine surgeons nationally for the same pathology in similar patients.

Cost-Effectiveness Analysis in Radiology: A Systematic Review.

Purpose: Cost-effectiveness analyses (CEAs) have become more prevalent in radiology. However, the lack of standard methodology may lead to conflicting conclusions on the cost-effectiveness of an imaging modality and hinder CEA-based policy recommendations. This study reviews recent CEAs to identify areas of methodological variation, explore their impact on interpretation, and discuss optimal strategies for performing CEAs in radiology.

Clinical Access and Utilization of Reports and Images in Neuroradiology.

Background: The radiology report serves as the primary means of communication between radiologist and clinician. However, the value clinicians place on imaging and reports is variable, with many images of studies or their reports never being viewed. This has implications on the perceived value of the radiologist in the imaging chain.

Cervical spine surgery for tandem spinal stenosis: The impact on low back pain.

Study Design: Retrospective Cohort.

Objective: Tandem spinal stenosis (TSS) can present similarly to cervical myelopathy, but often has a worse prognosis. Few studies have investigated outcomes and compared treatment approaches for patients with TSS.

Transitioning to a High-Value Health Care Model: Academic Accountability.

Health care spending in the United States has increased to unprecedented levels, and these costs have broken medical providers' promise to do no harm. Medical debt is the leading contributor to U.S.

Eliminating Creatine Kinase-Myocardial Band Testing in Suspected Acute Coronary Syndrome: A Value-Based Quality Improvement.

Cardiac biomarker testing is estimated to occur in nearly 30 million emergency department visits nationwide each year in the United States. The American College of Cardiology/European Society of Cardiology indicate that cardiac troponin is the biomarker of choice owing to its nearly absolute myocardial tissue specificity and high clinical sensitivity for myocardial injury. Multiple academic medical centers have implemented interventions to eliminate the routine ordering of creatine kinase-myocardial band tests, with published patient safety outcomes data; however, creatine kinase-myocardial band testing is still ordered in many hospitals and emergency departments.
