1) Spectral detector CT  recent introduction to dual layer technology imaging. 2) This technology potentially offers advantages due to spatial and temporal registration and improved beam hardening correction due to projection domain technique. 3) The retrospective availability of spectral data enables several cardiovascular applications using this novel technology.  

- Spectral dector CT using dual-layer detector technology - Physics - Phantom studies in cardiovascular imaging - Advantages of  spectral detector technology - Cardiovascular applications of spectral CT with illustrations o Myocardial perfusion imaging- Qualitative and quantitative analysis o Atherosclerotic plaque characterization o Generating optimal virtual monoenergetic image for luminal depiction in coronary arteries o Virtual calcium scoring from CTA o Decreased calcium blooming artifact using monoenergetic high keV images o Metal artifact reduction with monoenergetic images - Pacemakers, sternal wires, clips, and stents o Contrast boosting using low keV images - reducing contrast dose, salvage suboptimal studies o Virtual non-contrast images – shortening examination times and saving radiation dose - Limitations and pitfalls
