Differences between CMR measurements and actual results with correlation coefficients in explanted canine hearts

	Reference (mold)	LAX	SAX 10 mm	SAX 8 mm	SAX 5 mm
LV Volume	23.3 ± 5.3 ml	-2.5 ± 1.1% CV = 1.18	-7.0 ± 7.8% CV = 3.63	-0.7 ± 4.6% CV = -12.1	+0.3 ± 5.3% CV = -12.7
LA Volume	11.8 ± 7.5 ml	-13.3 ± 7.0% CV = 1.61	-4.2 ± 6.9% CV = 3.49	-3.3 ± 6.9% CV = 6.07	+5.3 ± 9.1% CV = -9.24
LV Mass	99.6 ± 5.5 g	-3.3 ± 3.0% CV = 2.68	+7.5 ± 5.6% CV = -3.49	+4.0 ± 4.2% CV = -5.31	+0.1 ± 6.0% CV = 17.3

Difference CV shows the degree of variation by providing the ratio of the standard deviation relative to the mean. Values are expressed as mean ± SE. LV: Left ventricular; LA: Left atrial; LAX: Long axis method; SAX: Short axis method; CV: coefficient of variation of the difference between mold and CMR values.
