BACKGROUND
In patients with suspected or known hypertrophic cardiomyopathy (HCM), late gadolinium enhancement (LGE) provides diagnostic and prognostic value. However, contraindications and long-term retention of gadolinium have raised concern about repeated gadolinium administration in this population. Alternatively, native T
PURPOSE
To apply radiomic texture analysis on native T
STUDY TYPE
Retrospective interpretation of prospectively acquired data.
SUBJECTS
In all, 188 (54.7 ± 14.4 years, 71% men) with suspected or known HCM.
FIELD STRENGTH/SEQUENCE
A 1.5T scanner; slice-interleaved native T
ASSESSMENT
Left ventricular LGE images were location-matched with native T
STATISTICAL TESTS
Four sets of texture descriptors were applied to the training dataset for capture of spatially dependent and independent pixel statistics. Five texture features were sequentially selected with the best discriminatory capacity between LGE(+) and LGE(-) T
RESULTS
The selected texture features discriminated between LGE(+) and LGE(-) T
DATA CONCLUSION
Radiomic analysis of native T
