Original Research

Cardiac CT   Prognosis of CT-derived Fractional Flow Reserve in the Prediction of Clinical Outcomes   In this single-center real-world experience of intermediate-term outcomes, it was demonstrated that at a median follow-up of more than 1 year, a positive result at fractional flow reserve (FFR) derived from CT (or FFRCT) analysis was associated with a significantly increased risk of late revascularization and myocardial infarction.  Charis G. McNabney, Stephanie L. Sellers... Jonathan R. Weir-McCall

Cardiac MRI   Free-breathing Cardiorespiratory Synchronized Cine MRI for Assessment of Left and Right Ventricular Volume and Function in Sedated Children and Adolescents with Impaired Breath-holding Capacity   A free-breathing cardiorespiratory synchronized cine sequence acquires the complete cardiac cycle with adequate spatial, contrast, and temporal resolutions for evaluating ventricular morphology, volume, and function with image quality equivalent to that of the standard of reference breath-hold sequence.  Amol S. Pednekar, Siddharth Jadhav, Cory Noel, Prakash

Myocardial Imaging   Stress Myocardial Perfusion PET Provides Incremental Risk Prediction in Patients with and Patients without Diabetes   In this large cohort including nearly 2000 patients with diabetes, myocardial perfusion PET results provide powerful and incremental prognostic information with appropriate reclassification improvement in 39% of patients with diabetes.  Hicham Skali, Marcelo F.

Pulmonary Imaging   Predicting Outcome in Idiopathic Pulmonary Fibrosis: Addition of Fibrotic Score at Thin-Section CT of the Chest to Gender, Age, and Physiology Score Improves the Prediction Model   Incorporating semiquantitative fibrotic score from thin-section CT to gender, age, and physiology (GAP) score provides an improved prediction model for survival in patients with idiopathic pulmonary fibrosis, especially in early-stage or mild disease.  Anurag Chahal, Roozbeh Sharif... Sushilkumar Sonavane

Vascular Imaging   Two-Minute k-Space and Time–accelerated Aortic Four-dimensional Flow MRI: Dual-Center Study of Feasibility and Impact on Velocity and Wall Shear Stress Quantification   The feasibility of 2-minute aortic four-dimensional flow MRI in 68 healthy volunteers and patients from two centers is shown, providing reproducible velocity and wall shear stress indices sensitive to expected aging- and disease-related aortic hemodynamic alterations.
