Summary of the results

Patient	Study type	Correlation (ref. vs. svm)	Jaccard (ref. vs. svm)	Jaccard (ref. vs. co)
1	Gated	0.72	0.82	0.60
	Free-breathing	0.69	0.82	0.61
2	Gated	0.77	0.96	0.73
	Free-breathing	0.86	0.96	0.81

ref. vs. svm = comparison of the reference data with the results obtained using the support vector machine–based algorithm (correlation coefficient between the threshold values, and geometric similarity coefficient between the delineated regions); ref. vs. co = comparison of the reference data with the results obtained using the contrast-oriented algorithm ¹⁵ (geometric similarity coefficient between the delineated regions).
