Dual-energy CT revisited with multidetector CT: review of principles and clinical applications.
Although dual-energy CT (DECT) was first conceived in the 1970s, it was not widely used for CT indications. Recently, the simultaneous acquisition of volumetric dual-energy data has been introduced using multidetector CT (MDCT) with two X-ray tubes and rapid kVp switching (gemstone spectral imaging). Two major advantages of DECT are material decomposition by acquiring two image series with diff...
متن کاملDual-energy CT in oncology: technical principles and clinical prospects
Learning objectives • Dual-energy CT (DECT) can amply contribute to a more efficient workflow in oncologic imaging. • DECT has the potential to reduce the radiation dose and to replace classical dual-phase protocols. • DECT improves oncologic imaging with improved tumour detection and opens up avenues for tissue differentiation and characterisation. • DECT allows for optimised and repeatable th...

متن کاملA novel dual energy CT-based attenuation correction method in PET/CT systems: A phantom study
In present PET/CT scanners, PET attenuation correction is performed by relying on the information given by CT scan. In the CT-based attenuation correction methods, dual-energy technique (DECT) is the most accurate approach, which has been limited due to the increasing patient dose. In this feasibility study, we have introduced a new method that can implement dual-en...
