Economic impact of spectral body imaging in diagnosis of patients suspected for occult cancer

open access: yesInsights into Imaging, 2021
Background Based on prior studies spectral CT has shown a higher sensitivity for malignant lesions than conventional CT at the cost of lower specificity. For the radiologists, it also offers a higher degree of certainty in the diagnosis of benign lesions.

Spatial-spectral cube matching frame for spectral CT reconstruction [PDF]

open access: yesInverse Problems, 2018
Abstract Spectral computed tomography (CT) reconstructs the same scanned object from projections of multiple narrow energy windows, and it can be used for material identification and decomposition. However, the multi-energy projection dataset has a lower signal-noise-ratio (SNR), resulting in poor reconstructed ...
