放射線診断学において、American Journal of Roentgenology (AJR) がとても役立ちますよ、ということを以前お話ししましたが、 最新号（Volume 220 Issue 6 June 2023）から、下記2論文を紹介します。
「Ringlike Peripheral Increased Iodine Concentration for the Differentiation of Primary Lung Cancer and Pulmonary Metastases on Contrast-Enhanced Dual-Energy CT.（AJR 2023;220(6):20:828-837.）」
Dual-Energy CTを用いた肺結節の鑑別方法を提唱しています。
「Utility of Dark-Blood Dual-Energy CT Images for Predicting Vascular Involvement and R0 Resection in Patients With Pancreatic Cancer.（AJR 2023;220(6):20:838-849.）」
Dark-Blood Dual-Energy CTを用いた膵癌血管浸潤の評価を提唱しています。
