CT-Based Radiomics Nomogram: A Potential Tool for Differentiating Hepatocellular Adenoma From Hepatocellular Carcinoma in the Noncirrhotic Liver.

Acad Radiol 2020 May 5. Epub 2020 May 5.

Department of Radiology, the Affiliated Hospital of Qingdao University, No. 16 Jiangsu Road, Qingdao 266000, Shandong, China. Electronic address:

Rationale And Objectives: To evaluate the value of a radiomics nomogram for preoperative differentiating hepatocellular adenoma (HCA) from hepatocellular carcinoma (HCC) in the noncirrhotic liver.

Materials And Methods: One hundred and thirty-one patients with HCA (n = 46) and HCC (n = 85) were divided into a training set (n = 93) and a test set (n = 38). Clinical data and CT findings were analyzed. Read More

Full Resolution Simulation for Evaluation of Critical Care Imaging Interpretation; Part 1: Fixed Effects Identify Influences of Exam, Specialty, Fatigue, and Training on Resident Performance.

Acad Radiol 2020 May 3. Epub 2020 May 3.

Department of Radiology, University of Florida Health Center, P.O. Box 100374, JHMHC, 1600 SW Archer Road, Gainesville, FL 32610-0374.

Rationale And Objectives: To describe our full-resolution simulation of critical care imaging coupled with posthoc grading of resident's interpretations and present results from the fixed effects terms in a comprehensive mixed regression model of the resulting scores.

Materials And Methods: The system delivered full resolution DICOM studies via clinical-grade viewing software integrated with a custom built web-based workflow and reporting system. The interpretations submitted by participating residents from 47 different programs were graded (scores of 0-10) on a case by case basis by a cadre of faculty members from our department. Read More

Impact of Age, Race, and Socioeconomic Status on Women's Perceptions and Preferences Regarding Communication of Estimated Breast Cancer Risk.

Acad Radiol 2020 May 3. Epub 2020 May 3.

University of Massachusetts Medical School, 55 N Lake Ave, Worcester, MA 01655. Phone: (508) 856-8798. Fax (508) 856-8993. Electronic address:

Rationale And Objectives: Performing breast cancer risk assessment at the time of screening mammography has potential to increase high-risk identification, appropriate supplemental screening, and risk management. The study's goal is to investigate women's interest in risk assessment and preferred method of risk communication in a diverse patient population.

Materials And Methods: Surveys in English and five non-English languages were distributed to women presenting for screening mammography at eight screening mammography facilities between February and May 2019 to assess their interest in risk assessment, preferred method, and level of detail of estimated risk communication in hypothetical scenarios where estimated risks are average and elevated.

The Diagnostic Value of Conventional MRI and CT Features in the Identification of the IDH1-Mutant and 1p/19q Co-Deletion in WHO Grade II Gliomas.

Acad Radiol 2020 Apr 28. Epub 2020 Apr 28.

Department of Neurosurgery, First Medical Center, Chinese PLA General Hospital, Beijing, China. Electronic address:

Rationale And Objectives: The classification of patients based on pathology and molecular features is important for improving WHO grade II glioma patient prognosis, especially for the initially diagnosed patients. Less invasive and more convenient methods for the prediction of the pathological type and gene status are desired.

Materials And Methods: This study investigates the ability to use conventional magnetic resonance imaging (MRI) and computed tomography (CT) features for determining the Isocitrate Dehydrogenase (IDH)-mutant and 1p/19q-codeletion status, through a retrospective review of information obtained from 189 WHO grade II glioma patients.
