Flow of patient material selection for developing and testing the virtual native enhancement technology. *The excluded T1 maps (n=10) in testing materials are disclosed in Figure III in the Data Supplement. **Four of the 36 triplets were retrospectively excluded from analysis because of slice position mismatch and coil problems identified by consensus of 2 cardiovascular magnetic resonance experts (see Figure IV in the Data Supplement). These examples were not detected automatically using the predefined criteria in slice position matching, and were excluded after manual inspection. HCMR indicates Hypertrophic Cardiomyopathy Registry; LGE, late gadolinium enhancement; and VNE, virtual native enhancement.
