WebFeb 8, 2024 · • The performance of dual-energy CT for patient management is not superior to that reported in literature for single-energy CT (0.83 sensitivity and 0.96 specificity). • Dual-energy CT did not yield substantial advantages in the identification of patients with acute pulmonary embolism compared to single-energy techniques. WebThe two acquisition systems are mounted on the rotating gantry with an angular offset of 90° (first-generation dual-source CT) or 95° (second-generation dual-source CT). For DECT acquisitions, the tube voltage is set at high energy (140 kVp) for one tube and at lower energy (80 or 100 kVp) for the other tube.
