Cover Story: Dual-energy CT has been successfully used in clinical practice for advanced tissue characterization beyond that of conventional CT. Several applications can be applied during the post-processing phase to significantly enhance the quality of diagnoses in oncology patients. On the one hand, it can improve the ability to identify hypervascularized and hypovascularized primary lesions, thanks to the use of applications related to iodine maps and monoenergetic applications. On the other hand, numerous other applications can enhance diagnostic accuracy in terms of the sensitivity and specificity of computed tomography in assessing potential complications in oncology patients. Also, DECT objective measurements can be utilized for monitoring treatment response in oncologic patients. View this paper
