Assessment of Myocardial Bridge and Mural Coronary Artery Using ECG-Gated 256-Slice CT Angiography: A Retrospective Study

Figure 4

The comparison of the percent change in thickness of MB, diameter and length of MCA from ED to ES phase. The bar graph showed that the percent of thickness change (Δthickness) of MB was the largest from ED to ES phase, followed by the percent of diameter change (Δdiameter) of MCA, and the percent of length change (Δlength) was the least.
