Abstract: Dual-energy CT, the object is scanned at two different energies, makes it possible to identify the characteristics of materials that cannot be evaluated on conventional single- energy CT images. This imaging method can be used to perform material decomposition based on differences in the material- attenuation coefficients at different energies. Dual- energy analyses can be classified as image data- based- and raw data- based analysis. the beam- hardening effect is lower with raw data based analysis, resulting in more accurate daul- energy analysis. on virtual monachromatic images, the iodine contrast increases as the energy level decreases; this improves visualization of contrast- enhanced lesions. Also the application of material decomposition, such as iodine and edema images, increases the detectability of lesions due to diseases encountered in daily clinical practice in this review, the minimal essentials of dual-energy CT scanning are presented and its usefulness in daily clinical practice is discussed.
