“…In the arterial phase, analyzing via VMI60 keV with a cut-off value of 68.42 HU demonstrated a good diagnostic performance in differential diagnosis with an AUC of 0.978; otherwise, the same analysis in the venous phase VMI70 keV with a cut-off value of 59.77 HU achieved a good diagnostic performance in differential diagnosis, with an AUC of 0.956. The IC evaluation with cut-off values of 10.99 mg/dL and 11.05 mg/dL, used to distinguish small neoplasms from thymic cysts, presented an AUC of 0.956 and 0.924, respectively [64]. Rajamohan N. et al revealed several parameters with excellent diagnostic performances in CT texture analysis for differentiating thymoma from thymic hyperplasia, low from high thymoma (WHO grade), and low from high Masaoka Koga/International Thymic Malignancy Interest Group stages [98].…”

Dual-energy computed tomography (DECT) is one of the most promising technological innovations made in the field of imaging in recent years. Thanks to its ability to provide quantitative and reproducible data, and to improve radiologists’ confidence, especially in the less experienced, its applications are increasing in number and variety. In thoracic diseases, DECT is able to provide well-known benefits, although many recent articles have sought to investigate new perspectives. This narrative review aims to provide the reader with an overview of the applications and advantages of DECT in thoracic diseases, focusing on the most recent innovations. The research process was conducted on the databases of Pubmed and Cochrane. The article is organized according to the anatomical district: the review will focus on pleural, lung parenchymal, breast, mediastinal, lymph nodes, vascular and skeletal applications of DECT. In conclusion, considering the new potential applications and the evidence reported in the latest papers, DECT is progressively entering the daily practice of radiologists, and by reading this simple narrative review, every radiologist will know the state of the art of DECT in thoracic diseases.
