Abstract:<p>Image perturbation is the promising technique to assess radiomic feature repeatability without test-retest imaging. However, whether it can achieve the same effect on model reliability enhancement as test-retest imaging is unknown. This study aimed to compare radiomic model reliability based on repeatable features determined by image perturbation and test-retest imaging. A 191-patient public breast cancer dataset with 71 test-retest scans was used with pre-determined 117 training and 74 testing sample… Show more
