Background: Pleural effusion is a common clinical problem. The ability to differentiate between benign and malignant pleural effusions has many benefits. However, few studies have investigated the diagnostic value of dual-energy spectral computed tomography (DECT) in effusion. Objective: To evaluate values DECT for assessment Materials Methods: We retrospectively analyzed data from 87 patients ...

To identify the optimal monochromatic energy of the dual energy spectral CT Angiography (CTA) of celiac artery with high image quality. 32 patients were tested by the contrast-enhanced CT with the dual energy spectral imaging mode. Based on the polychromatic data, images of celiac artery were reconstructed at the optimal monochromatic energy, 70 keV monochromatic energy level and the 140 kVp tu...
