The inherent spectral capabilities of Mayo Clinic's new third-generation photon-counting CT research scanner allows clear visualization of the intact portions of the coronary artery lumen (arrowhead) by reducing the bright signal from the dense coronary calcifications (arrows). Spectral CT is able to bin photos on different energies that can be used to enhance or subtract chemical elements based on their spectral signature, such as calcium shown here, and iodine.
