Differential diagnosis between benign and malignant pleural effusion with dual-energy spectral CT.

ABSTRACT:

Purpose

To investigate the value of spectral CT in the differential diagnosis of benign from malignant pleural effusion.

Method and materials

14 patients with benign pleural effusion and 15 patients with malignant pleural effusion underwent non-contrast spectral CT imaging. These patients were later verified by the combination of disease history, clinical signs and other information with the consensus of surgeons and radiologists. Various Spectral CT image parameters measured for the effusion were as follows: CT numbers of the polychromatic 140kVp images, monochromatic images at 40keV and 100keV, the material density contents from the water, fat and blood-based material decomposition images, the effective atomic number and the spectral curve slope. These values were statisti
