Gemstone Spectral Imaging with Dual-Energy CT for the Differential Diagnosis of Prostate Cancer and Benign Prostatic Hyperplasia Using

Objective To evaluate the clinical utility of Gemstone spectral imaging( GSI) for the differentiation of prostate cancer( PCa) from benign prostatic hyperplasia( BPH). Methods Thirty three patients with PCa and 38 patients with BPH were recruited and underwent GSI with dual-energy CT,with histopathologic findings regarded as the reference standard. Monochromatic images,material-decomposition images,polychromatic image sets with photon energies...
