Imaging of aortic coarctation using Gd-DTPA and Gadofosveset: a comparative study

Table 1 Values are expressed as mean ± standard deviation

Contrast Agent	Sequence	Contrast to Noise Ratio (CNR)	Vessel Wall sharpness (%)	Image quality (mean ± SD)	Vessel Area (cm²)	Isotropic spatial resolution (mm³)
Gd-DTPA	CEMRA	110 ± 10^†	41 ± 4^†	2.4 ± 0.8^†	4.6 ± 1.9^†	1.77
	SSFP	135 ± 11*	48 ± 6*	3.3 ± 0.5*	4.1 ± 1.7*	1.49
Gadofosveset	CEMRA	99 ± 21^†	40 ± 4^†	2.7 ± 0.5^†	4.7 ± 2.1^†	1.77
	SSFP	128 ± 19*	46 ± 3*	3.1 ± 0.7*	4.1 ± 1.6*	1.49

^†*, no significant differences between corresponding sequences (Gd-DTPA vs Gadofosveset). Image quality: 1 = non diagnostic, 2 = diagnostic, 3 = good, 4 = excellent.
