The result suggests that proposed endocardial deformation analysis using CT can be conducted on site and in time for the acute
setting, and may be useful for the diagnosis of cardiac dysfunction or myocardial ischemia.

From July 2016 to February 2017, cardiac CT data were collected from ten consecutive subjects (41-80 years old) who underwent a coronay CT examination for clinical reasons at Hokkaido University Hospital.
Retrospective analysis of patient data undergoing coronary CT
None
Our study of 65 endocardial segments in ten subjects showed that global endocardial deformation has a positive relationship with the stroke volume index (r = 0.896 and 0.829 in E and S, respectively) and ejection fraction (r = 0.804 and 0.835). A positive relationship between segmental E and S (r = 0.845), a higher value of E in ischemic segments (p = 0.021) that are determined by fractional flow reserve estimated from coronary CT data, and a higher value of S in the left circumflex artery territory (p < 0.05) were also observed. The required radiation dose was 5.0 +- 0.7 mSv and the computation time was 7.2 +- 1.1 min.
