Background: Hemoptysis is common following percutaneous image-guided cryoablation of pulmonary tumors. Objective: To evaluate the effect of a final active thaw on the incidence, grade, and onset of hemoptysis following percutaneous cryoablation of pulmonary tumors. Methods: This retrospective cohort study included 60 consecutive CT-guided cryoablation sessions targeting 95 pulmonary tumors in 47 patients from 2017 to 2020. The final thaw of a triple-freeze protocol was active (electrical, helium...

Background: Extension of type A aortic dissection (TAAD) from the sinus of Valsalva (SV) into the coronary arteries is associated with worse prognosis and requires direct coronary repair or coronary artery bypass graft (CABG) depending on extent of involvement. Objectives: To assess the diagnostic performance of ECG-gated aortic CTA for detection and classification of coronary artery involvement in patients with TAAD involving the SV, using surgical findings as reference. Methods: This retrospec...
Increasing healthcare consumerism has been proposed as a solution for rising U.S. healthcare costs. While price transparency initiatives aim to inform patients about out-of-pocket costs (OOPC), challenges remain regarding price transparency tools, including limited accuracy of estimates, accounting for multiple payers for the same service, need for quality measures, optimal OOPC delivery, and psychosocial consequences of OOPC information. As radiology practices consider implementing price transp...
Background: COVID-19 vaccination may trigger reactive lymphadenopathy, confounding imaging interpretation. There has been limited systematic analysis of PET findings after COVID-19 vaccination. Objective: To evaluate the frequency and characteristics of abnormal FDG and 11C-choline uptake on PET imaging performed after COVID-19 vaccination. Methods: This retrospective study included 67 patients (mean age 75.6±9.2 years; 43 men, 24 women) who underwent PET examination (PET/CT in 66, PET/MRI in 1;...

You are consulted regarding an 83-year-old healthy woman who underwent renal protocol CT for a 3.6 cm renal mass. The CT was degraded by motion artifact but showed indeterminate (17 HU) enhancement in the mass, reported as suspicious for papillary renal cell carcinoma. What do you recommend for further management?

Background: Despite numerous published studies, management of benign papillomas without atypia remains controversial. Objective: To determine the malignancy upgrade rate of benign papillomas, identify risk factors for upgrade, and formulate criteria for selective surgery. Methods: This retrospective study included benign papillomas without atypia diagnosed on percutaneous biopsy between 12/01/2000 and 12/31/2019. Papillomas that did not undergo surgical excision or at least 2 years of imaging an...
