Dual-energy CT arthrography: a feasibility study

To evaluate the feasibility of producing 2-dimensional (2D) virtual noncontrast images and 3-dimensional (3D) bone models from dual-energy computed tomography (DECT) arthrograms and to determine whether this is best accomplished using 190 keV virtual monoenergetic images (VMI) or virtual unenhanced (VUE) images. VMI and VUE images were retrospectively reconstructed from patients with internal derangement of the shoulder or knee joint who...
