Myocardial, blood pool, and 3D ECV values.

Parameters	Healthy group (n = 9)	Subjects with diastolic heart failure (n = 5)	Subjects with systolic heart failure (n = 10)	P value
Before contrast
Myocardium, HU, mean ± SD	44.0 ± 5.2	43.0 ± 4.7	38.1 ± 10.9	0.27
Blood pool, HU, mean ± SD	43.2 ± 3.4	46.5 ± 4.5	41.3 ± 8.7	0.34
After contrast
Myocardium, HU, mean ± SD	82.6 ± 14.2	97.9 ± 5.1	90.3 ± 18.4	0.20
Blood pool, HU, mean ± SD	110.0 ± 22.38	136.5 ± 11.0	117.25 ± 30.5	0.18
ECV
3D ECV, %, mean ± SD	33.8 ± 2.6^*,^†	35.7 ± 5.8^†	40.8 ± 6.8^*	0.02

3D, 3-dimensional; ECV, extracellular volume fraction.

After post hoc Bonferroni correction, 3D ECV of patients with systolic heart failure was significantly greater than that of control subjects (P = 0.01).

^†

The 3D ECV of patients with diastolic heart failure was not significantly different than that of control subjects (P = 0.51).
