Gastrointestinal Imaging,   Shear-Wave Dispersion Slope from US Shear-Wave Elastography: Detection of Allograft Damage after Liver Transplantation   Shear-wave dispersion slope determined at two-dimensional US shear-wave elastography provides high sensitivity and negative predictive value in detecting allograft damage after liver transplant.     Dong Ho Lee, Jae Young Lee...Joon Koo Han

Preoperative CT Classification of the Resectability of Pancreatic Cancer: Interobserver Agreement   Considerable interobserver variability exists in the assignment at CT of local resectability of pancreatic cancer, even amongst experienced radiologists.     Ijin Joo, Jeong Min Lee...Hyun Kyung Yang

Genitourinary Imaging   Diagnostic Accuracy of Multiparametric MRI versus 68Ga-PSMA-11 PET/MRI for Extracapsular Extension and Seminal Vesicle Invasion in Patients with Prostate Cancer   While overall diagnostic performance in local staging of patients with prostate cancer at intermediate to high risk was similar, use of a gallium 68 (68Ga)-labeled Glu-urea-Lys (Ahx)-HBED-CC ligand targeting the prostate-specific membrane antigen (PSMA) (68Ga-PSMA-11) PET/MRI may improve the sensitivity of multiparametric MRI for the detection of extracapsular disease, at the cost of a slightly reduced specificity.     Urs J. Muehlematter, Irene A. Burger...Olivio F. Donati

Musculoskeletal Imaging   Statin Use and Knee Osteoarthritis Outcome Measures according to the Presence of Heberden Nodes: Results from the Osteoarthritis Initiative   This observational analysis shows that statin use may reduce the risk of radiographic knee joint space narrowing progression in patients with nodal (Heberden node–positive) knee osteoarthritis, indicative of a distinct pleiotropic statin effect.     Arya Haj-Mirzaian, Bahram Mohajer...Shadpour Demehri

Reviews and Commentary

Review   Review of Clinical Applications for Virtual Monoenergetic Dual-Energy CT   A growing body of literature encourages routine implementation of virtual monoenergetic imaging for dual-energy CT because it affords fewer beam-hardening artifacts, reduced iodine dose, and better contrast between enhancing and nonenhancing areas, ultimately providing greater diagnostic value.     Moritz H. Albrecht, Thomas J. Vogl...U. Joseph Schoepf
