Table 2 Comparison of contrast values for 2D and 3D high-dose (HD) and 3D low-dose (LD) in ⁸²Rb PET myocardial imaging – sharper filter H13

From: Comparison of 2D, 3D high dose and 3D low dose gated myocardial ⁸²Rb PET imaging

	2D	HD-3D	2D	LD-3D
Contrast	0.48	0.50	0.33	0.34
NAS × 10-4	4.43	5.17	8.18	9.18***
NWS × 10-2	2.00	2.00	2.00	2.00

***p < 0.001 vs HD
NAS = noise among segments NWS = noise within segments
