Scatterplot of thoracic aortic calcification volume measured by radial-VIBE against CT. Red solid line is the line of best fit and green dashed lines represent its 95% confidence intervals (CI); black dashed line is the line of unity. The linear regression equation and R-squared value are on the bottom right; Spearman’s rank correlation coefficient \((\rho )\), with its 95% CI and p-value, are on the top left
