Pulmonary Imaging,   Electronic Cigarette or Vaping-associated Lung Injury (EVALI): The Tip of the Iceberg,   Radiologists will continue to play an important role in understanding and interpreting radiologic findings of lung injury in those with a history of using e-cigarette or vaping products.     Suhny Abbara, Fernando Uliana Kay

Original Research

Cardiac CT   Diagnostic Performance of On-Site Coronary CT Angiography–derived Fractional Flow Reserve Based on Patient-specific Lumped Parameter Models   Diagnostic performance of on-site coronary CT angiography–derived fractional flow reserve was superior to stenosis evaluation at coronary CT angiography for identification of functionally significant coronary artery stenosis in patients suspected of having or known to have coronary artery disease.     Robbert W. van Hamersvelt, Michiel Voskuil...Tim Leiner

Cardiac CT   False-Negative Low Tube Voltage Coronary CT Angiography: High Intravascular Attenuation at Coronary CT Angiography Can Mask Calcified Plaques   Low tube voltage coronary CT angiography performed without a concomitant coronary calcium scoring scan may give false-negative results in patients with low plaque burden.     Vinit Baliyan, Jan-Erik Scholtz...Brian B.

Cardiac MRI   Respiration Dependency of Caval Blood Flow in Patients with Fontan Circulation: Quantification Using 5D Flow MRI   A cardiac- and respiration-resolved three-directional and three-dimensional phase-contrast MRI sequence was applied in 10 volunteers and six patients with Fontan circulation, and blood flow rates and flow distribution were shown to be affected by respiration in the total cavopulmonary connection of patients with Fontan circulation.     Rene Bastkowski, Robert Bindermann...Daniel Giese

Cardiac MRI   Myocardial Stress Perfusion MRI Using Regadenoson: A Weight-based Approach in Infants and Young Children   Weight-based dosing of regadenoson for stress cardiac MRI was safe and feasible in infants and young children less than 40 kg and impacts clinical decision-making.     James C. Wilkinson, Tam T. Doan...Cory V. Noel

Chest CT   Accuracy of Non–Electrocardiographically Gated Thoracic CT Angiography for Right Atrial and Right Ventricular Enlargement   Right ventricular enlargement and right atrial enlargement can be identified using non–electrocardiographically gated CT angiography.     Zachary Nuffer, Timothy M. Baran...Abhishek Chaturvedi

Cardiac MRI   Feature-Tracking MRI Fractal Analysis of Right Ventricular Remodeling in Adults with Congenitally Corrected Transposition of the Great Arteries   The results of fractal analysis performed by using feature-tracking cardiac MRI correlated with adverse remodeling of the right ventricle, including changes in the strain pattern and trabeculae of the ventricle, in patients with congenitally corrected transposition of the great arteries.     Masateru Kawakubo, Michinobu Nagao...Shuji Sakai

Cardiac MRI   Global Longitudinal Strain Analysis Using Cardiac MRI in Aortic Stenosis: Comparison with Left Ventricular Remodeling, Myocardial Fibrosis, and 2-year Clinical Outcomes   Global longitudinal strain by using cardiac MRI is a widely available functional surrogate of myocardial fibrosis but is limited by overlap between diseases and does not provide additional prognostic information beyond established cardiac MRI assessments; its clinical utility may be greater when assessing changes over time.     Nicholas B. Spath, Miquel Gomez...Marc R. Dweck

Cardiac MRI   Eosinophillic Myocarditis Secondary to Metastatic Melanoma   In the presence of hypereosinophilia and findings consistent with myocarditis at transesophageal echocardiography and cardiac MRI, a diagnosis of eosinophilic myocarditis secondary to metastatic melanoma was made.     Robyn E.
