Purpose To evaluate interradiologist agreement on assessments of computed tomography (CT) imaging features of high-grade serous ovarian cancer (HGSOC), to assess their associations with time-to-disease progression (TTP) and HGSOC transcriptomic profiles (Classification of Ovarian Cancer [CLOVAR]), and to develop an imaging-based risk score system to predict TTP and CLOVAR profiles. Materials and Methods This study was a multireader, multi-institutional, institutional review board-approved, HIPAA-compliant retrospective analysis of 92 patients with HGSOC (median age, 61 years) with abdominopelvic CT before primary cytoreductive surgery available through the Cancer Imaging Archive...

PURPOSE: To measure the apparent diffusion coefficient (ADC) values in estrogen receptor-positive (ER+) and axillary lymph node-negative (LN-) invasive breast cancer and investigate the correlation of ADC with Oncotype Dx test recurrence scores (ODxRS). MATERIALS AND METHODS: This was a Health Insurance Portability and Accountability Act (HIPAA)-compliant single-site retrospective study. Patients underwent preoperative 3.0T MRI scans with additional diffusion-weighted imaging sequential scans (b = 0, 600 and b = 0, 1000 s/mm(2) ) from January 2011 to 2013...

To design and conduct a survey analyzing pre-, intra- and post- hip arthroscopy practice patterns among hip arthroscopists worldwide. A 21-question, IRB-exempt, HIPAA-compliant, cross-sectional survey was conducted via email using SurveyMonkey to examine pre-operative evaluation, intra-operative techniques and post-operative management. The survey was administered internationally to 151 hip arthroscopists identified from publicly available sources. Seventy-five respondents completed the survey (151 ± 116 hip arthroscopy procedures per year; 8...

PURPOSE: To describe success rates and long-term outcomes of conjunctivodacryocystorhinostomy (CDCR) with larger collar (4.5 or 5.0 mm) frosted Jones tubes (FJTs). METHODS: A retrospective chart review of all patients who received a larger collar (4.5 or 5.0 mm) FJT following CDCR by an author (RAD) was performed between January 1, 2010 and July 1, 2016. Patient demographics, etiology of tearing, follow-up time from placement of larger collar FJT, original tube collar diameter, number and sizes of collar adjustments, tearing status, and complications were recorded...

De-identification of clinical narratives is one of the main obstacles to making healthcare free text available for research. In this paper we describe our experience in expanding and tailoring two existing tools as part of the 2016 CEGS N-GRID Shared Tasks Track 1, which evaluated de-identification methods on a set of psychiatric evaluation notes for up to 25 different types of Protected Health Information (PHI). The methods we used rely on machine learning on either a large or small feature space, with additional strategies, including two-pass tagging and multi-class models, which both proved to be beneficial...

Purpose To correlate multiparametric magnetic resonance (MR) imaging and quantitative digital histopathologic analysis (DHA) of the prostate. Materials and Methods This retrospective study was approved by the local institutional review board and was HIPAA compliant.

PURPOSE: Technology has enhanced modern health care delivery, particularly through accessibility to health information and ease of communication with tools like mobile device messaging (texting). However, text messaging has created new risks for breach of protected health information (PHI). In the current study, we sought to evaluate hand surgeons' knowledge and compliance with privacy and security standards for electronic communication by text message. METHODS: A cross-sectional survey of the American Society for Surgery of the Hand membership was conducted in March and April 2016...

OBJECTIVES: To determine the accuracy of post-operative MR in predicting residual disease in women with positive margins, emphasizing the size thresholds at which residual disease can be confidently identified. METHODS: This IRB-approved HIPAA-compliant retrospective study included 175 patients with MR after positive margins following initial surgery for breast cancer.

RATIONALE AND OBJECTIVES: To investigate whether imaging features on multiphasic multidetector computed tomography (MDCT) can help discriminate sarcomatoid renal cell carcinoma (RCC) and collecting duct carcinoma (CDC) from other solid renal masses. MATERIALS AND METHODS: With institutional review board approval for this HIPAA-compliant study, we derived a cohort of 7 sarcomatoid RCCs, 4 CDCs, 165 clear cell RCCs, 56 papillary RCCs, 22 chromophobe RCCs, 49 oncocytomas, and 16 lipid-poor angiomyolipomas with preoperative multiphasic MDCT with up to four phases (unenhanced, corticomedullary, nephrographic, and excretory)...

PURPOSE: This randomized, double-blind controlled study evaluated the effectiveness of sodium bicarbonate-buffered lidocaine on reducing pain during imaging-guided breast biopsies. MATERIALS AND METHODS: This prospective, HIPAA-compliant study randomly assigned 85 women undergoing ultrasound- or stereotactic-guided core-needle breast biopsies to receive intradermally and intraparenchymally either 1% lidocaine buffered with sodium bicarbonate (9:1 ratio) (bicarbonate study group) or 1% lidocaine alone (control group)...

Background.: Patient engagement efforts often rely on a participatory research approach, which means engaging patients and community members in all aspects of research. As research team members, they require familiarity with the principles of human subject protection, privacy, and institutional review boards (IRB). However, the time required for individual IRB training may be a barrier to engaging community members in participatory research. As more community members participated in research, the State Networks of Colorado Practices and Partners (SNOCAP) was faced with finding a balance between including community members as part of the research team and the significant time commitment and institutional requirements for human subjects research oversight...

Purpose To evaluate associations between pulmonary function and both quantitative analysis and visual assessment of thin-section computed tomography (CT) images at baseline and at 15-month follow-up in subjects with idiopathic pulmonary fibrosis (IPF). Materials and Methods This retrospective analysis of preexisting anonymized data, collected prospectively between 2007 and 2013 in a HIPAA-compliant study, was exempt from additional institutional review board approval. The extent of lung fibrosis at baseline inspiratory chest CT in 280 subjects enrolled in the IPF Network was evaluated...
