Transition From Peer Review to Peer Learning: Lessons Learned.

Landmark publications, such as To Err is Human, confronted the healthcare community with the egregious toll medical errors played in both patient safety and overall healthcare costs. This heralded a paradigm shift and a call for action by professional organizations to enact methods to ensure physician competency and quality assurance. The American College of Radiology similarly convened a task force to discuss these concerns and how best to address quality assurance in radiology practice, leading to the development of RADPEER, a score-based peer review system.

Analysis of Imaging Results for Semisitting Compared with Supine Positioning in the Retrosigmoid Approach for Resection of Cerebellopontine Angle Vestibular Schwannomas.

Objective: To compare the completeness of resection of vestibular schwannomas using three-dimensional segmented volumetric analysis of pre- and postoperative magnetic resonance imaging (MRI) of patients undergoing supine and semisitting positioning for the retrosigmoid approach.

Study Design: Retrospective chart review.

Setting: Tertiary medical center.

Rates of bone reabsorption and union in mandibular reconstruction using the osteocutaneous radial forearm free flap.

Background: Historical concerns over bone resorption and malunion of the osteocutaneous radial forearm free flap (OCRFFF) limited its widespread adoption for head and neck reconstruction, despite lack of outcomes data evaluating this notion.

Methods: A retrospective cohort study was performed including patients 18 years or older who underwent reconstruction of the mandible using an OCRFFF. Linear modeling and logistic regression were used to evaluate the change in bone volume and union over time.

Computed Tomography Measurements in Assessment of Idiopathic Vocal Fold Paralysis.

Objective: Our study aimed to both identify the incidence and clinical presentation of patients presenting with idiopathic vocal fold paralysis (IVFP). Secondarily we aimed to assess the radiographic findings of computed tomography (CT) studies along the course of the vagus and recurrent laryngeal nerves (RLN), specifically measuring for potential areas of compression at the skull base and mediastinum. We hypothesized that a proportion of patients diagnosed with IVFP would have significant differences in measurements when compared to age-gender matched controls on CT imaging.

Augmenting Amyloid PET Interpretations With Quantitative Information Improves Consistency of Early Amyloid Detection.

Purpose: Establishing reliable methods for interpreting elevated cerebral amyloid-β plaque on PET scans is increasingly important for radiologists, as availability of PET imaging in clinical practice increases. We examined a 3-step method to detect plaque in cognitively normal older adults, focusing on the additive value of quantitative information during the PET scan interpretation process.

Methods: Fifty-five F-florbetapir PET scans were evaluated by 3 experienced raters.
