55 IQon Spectral CT retrospective gated cardiac CT Benefit Spectral based images were loaded into the Comprehensive Cardiac Application (CCA) allowing the physician to look at different spectral results and to evaluate the coronary artery segments. Case Summary Curved multi-planar reformation (CMPR) images were generated for spectral results to evaluate the coronary stent in the proximal LAD. MonoE and Z effective reconstructions were used for evaluation. These results allowed the clinician to identify a blockage in the proximal stent graph which was confirmed with the angiography

56 C-MPR RCA C-MPR LAD C-MPR LCx IQon Spectral CT cardiac Benefit Gated spectral cardiac capabilities allowed the physician to review the spectral cardiac anatomy immediately post scan. Case Summary 24 year old male admitted for atypical chest pain The EKG showed a suspected inferior wall infarction and his troponins were elevated. Due to his young age myocarditis was clinically entertained as a suspected diagnosis. A gated cardiac CTA scan was performed on the IQon Spectral CT that showed normal coronary arteries, but a suspicious area that was questionable for an infarct was identified in the inferior wall of the myocardium.
