Tóm tắt

The advent of photon-counting detector CT brought up various new interesting possibilities for coronary imaging including different scan modes and various post-processing options. The two main scan modes include spectral data acquisition with inherent energy-resolved imaging and ultra-high-resolution scanning with unprecedented high spatial resolution, both at the highest available temporal resolution. Post-processing options include the generation of virtual monoenergetic images at different levels and the generation of virtual non-calcium images. Many early studies indicated the potential of each of these options for coronary CT angiography but also show that much more work is needed to clarify the optimal scan mode for each individual patient and clinical setting.
