![]() Statistical analysis was used to build radiomic signatures with significant inter-group differences of NMIBCs and MIBCs. The radiomic features quantifying tumor signal intensity and textures were extracted from each VOI and its high-order derivative maps to characterize heterogeneity of tumor tissues. A total of 118 cancerous volumes of interest (VOI) were segmented from patientsâ T2 weighted MR images (T2WI), including 34 non-muscle invasive bladder carcinomas (NMIBCs, stage patients with clinicopathologically confirmed BC were included in this retrospective study. ![]() ![]() To determine radiomic features which are capable of reflecting muscular invasiveness of bladder cancer (BC) and propose a non-invasive strategy for the differentiation of muscular invasiveness preoperatively.
