Table 1 Comparison of the main diagnostic and quality assessment parameters for 2D and iNav3D LGE.

From: Clinical Evaluation of 3D High Resolution Late Enhancement using Image-Based Navigation

DIAGNOSTIC PERFORMANCE

2D (n = 22) 77% (17)
iNav3D (n = 22) 59% (13)
Segmental LGE detection (p, 0.28)
Number of segments 0 1 2 3 4 5
2D (n = 352) 75.9% (267) 10.2% (36) 3.7% (13) 7.7% (27) 2% (7) 0.6% (2)
