Pulmonary Embolism at CT Pulmonary Angiography in Patients with COVID-19.

Purpose: To evaluate pulmonary embolism (PE) prevalence at CT pulmonary angiography in patients testing positive for coronavirus disease 2019 (COVID-19) and factors associated with PE severity.

Materials And Methods: A retrospective, single-center study evaluated 62 patients who tested positive for COVID-19 who underwent CT pulmonary angiography between March 13 and April 5, 2020. Another 62-patient cohort who underwent CT pulmonary angiography before the first reported local COVID-19 case was retrospectively selected.

Effectiveness of Lung-RADS in Reducing False-Positive Results in a Diverse, Underserved, Urban Lung Cancer Screening Cohort.

Purpose: The Lung CT Screening Reporting and Data System (Lung-RADS) was created to standardize lung cancer screening CT reporting and recommendations but has not been well validated prospectively in clinical practice. The aim of this study was to determine the effectiveness of lung cancer screening using Lung-RADS in a diverse, underserved, academic clinical screening program, focusing on whether Lung-RADS would successfully reduce the 23.3% false-positive rate found in the National Lung Screening Trial.

Computed tomography screening for lung cancer: preliminary results in a diverse urban population.

Purpose: The purpose of this study was to describe the baseline characteristics and results of the initial 18 months of our clinical computed tomography (CT) lung cancer screening program in an ethnically diverse, poor, predominantly overweight, and obese population, which differs dramatically from the National Lung Screening Trial population.

Materials And Methods: All patients had a physician referral for CT lung cancer screening and met National Lung Screening Trial eligibility criteria. Infrastructure developed for the program included a standardized results report [Bronx score of 1 to 5 (modeled on BI-RADS)] for the electronic medical record and a dedicated bilingual screening coordinator.
