Dual-energy CT (DECT) imaging has broadened the potential of CT imaging by offering multiple postprocessing datasets with a single acquisition at more than one energy level. DECT shows profound capabilities to improve diagnosis based on its superior material differentiation and its quantitative value. However, the potential of dual-energy imaging remains relatively untapped, possibly due to its intricate workflow and the intrinsic technical limitations of DECT. Knowing the clinical advantages of dual-energy imaging and recognizing its limitations and pitfalls is necessary for an appropriate clinical use. The aims of this paper are to review the physical and technical bases of DECT acquisition and analysis, to discuss the advantages and limitations of DECT in different clinical scenarios, to review the technical constraints in material labeling and quantification, and to evaluate the cutting-edge applications of DECT imaging, including artificial intelligence, qualitative and quantitative imaging biomarkers, and DECT-derived radiomics and radiogenomics.

Imaging plays a crucial role in the management of patients with Lesions of splenium of corpus callosum (SCC) . The magnetic resonance (MRI) with the development of, new imaging techniques, improved the detection and characterization of Lesions of splenium of corpus callosum. This review provides a general description of splenium of corpus callosum injuries and their radiological

Introduction: The basal ganglia are paired deep gray matter structures that can be involved in a wide variety of diseases. However, only a few substances reduce T1 relaxation time, and they appear bright on T1-weighted images. These include methemoglobin, protein, calcium, different minerals, lipids, and melanin. Radiologists can detect Uni or bilateral abnormalities of the basal

There are many disorders that may involve the left ventricular (LV) apex; however, they are sometimes difficult to differentiate. In this setting cardiac imaging methods can provide the clue to obtaining the diagnosis. The purpose of this review is to illustrate the spectrum of diseases that most frequently affect the apex of the LV including Tako-Tsubo cardiomyopathy, LV aneurysms and pseudoaneurysms, apical diverticula, apical ventricular remodelling, apical hypertrophic cardiomyopathy, LV non-compaction, arrhythmogenic right ventricular dysplasia with LV involvement and LV false tendons, with an emphasis on the diagnostic criteria and imaging features.

OBJECTIVE. The objective of this article is to show how MRI findings can be used to differentiate Takotsubo cardiomyopathy from acute coronary syndrome.CONCLUSION. Takotsubo cardiomyopathy is a disorder that mimics acute coronary syndrome. MRI can show not only edema in the ventricular wall, which is diffuse and without arterial territory distribution, but also motion abnormalities with typical akinesis in the apical and mid planes. Moreover, MRI can detect potential complications such as obstruction of the left ventricular outflow tract or thrombus in the left ventricular cavity.
