Utility of Saline-Induced Resting Full-Cycle Ratio Compared with Resting Full-Cycle Ratio and Fractional Flow Reserve

Figure 1

A representative data. Saline-induced resting full-cycle ratio (sRFR) record from a 62-year-old man with stable angina. The red-arrow shows sRFR value in the present case. The white arrow shows the starting point of saline injection and the green arrow shows the ending point of saline injection.
