Key result
Semiautomated LGE cardiovascular MR gray-scale thresholding with 6 SDs above the mean provides a highly reproducible approximation of LGE extent in hypertrophic cardiomyopathy patients.
Why the study?
Does semiautomated LGE cardiovascular MR gray-scale thresholding with ≥6 SDs accurately quantify LGE compared to visual assessment in patients with HCM?
Does semiautomated LGE cardiovascular MR gray-scale thresholding with ≥6 SDs accurately quantify LGE compared to visual assessment in patients with HCM?
Semiautomated LGE cardiovascular MR thresholding at ≥6 SDs provides an objective and highly reproducible method for quantifying LGE in patients with hypertrophic cardiomyopathy.
