Key result
A set of parameters and visualizations for assessing global and regional left ventricle function across multiple cardiac phases from coronary CT angiography was presented to aid clinical exploration.
Why the study?
Does the analysis of multiple cardiac phases from coronary CT angiography provide further insight into regional and global left ventricle function compared to standard two-phase assessment?

Utilizing data from multiple cardiac phases during coronary CT angiography may provide clinicians with deeper insights into regional and global left ventricular function.
Coronary CT angiography is widely used in clinical practice for the assessment of coronary artery disease. Several studies have shown that the same exam can also be used to assess left ventricle (LV) function. Even though coronary CT angiography provides data concerning multiple cardiac phases, along the cardiac cycle, LV function is usually evaluated using just the end‐systolic and end‐diastolic phases. This unused wealth of data, mostly due to its complexity and the lack of proper tools, has still to be explored to assess if further insight is possible regarding regional LV functional analysis. Furthermore, different parameters can be computed to characterize LV function and though some are well known by clinicians others still need to be tested concerning their value in clinical scenarios. Based on these premises, we present several parameters characterizing global and regional LV function, computed for several cardiac phases over one cardiac cycle. The data provided by the computed parameters is shown using a set of visualizations allowing synchronized visual exploration of the different data. The main purpose is to provide means for clinicians to explore the data and gather insight over their meaning and their correlation with each other and with diagnosis outcomes.
