The diagnostic performance of bpMRI and mpMRI was analyzed by the area under the curve (AUC). We built multiple ML models for detecting csPCa. The input parameters were: PI-RADS scores in bpMRI or mpMRI, age, prostate-specific antigen (PSA), MRI-defined PSA density (PSAD), and prostate volume (PV).

All the ML models exhibited the high AUC in detecting csPCa (0.93–0.96 based on mpMRI models and 0.91–0.94 based on bpMRI models). There were no statistically significant differences in the AUC values between the two groups of ML models in test sets.</div></div><div><h3>Conclusions</h3><div>Compared to bpMRI, the AUC of mpMRI based on PI-RADS v2.1 to detect csPCa was higher.

It can be useful to support diagnosis and management, particularly in bone oncology. By analysing complex patterns within imaging data, radiomics can provide detailed insights into tumour characteristics that are not apparent through visual inspection alone. This approach leverages machine learning algorithms to identify and quantify features like texture, shape, and intensity of tumours, which can help in discriminating between benign and malignant lesions and predicting treatment response and outcome in malignant tumours. In bone tumour diagnosis, radiomics can improve accuracy in differentiating benign lesions from skeletal metastases and primary malignant tumours, identifying different bone-tumour histotypes, and predicting tumour grade. Regarding management, it aids in treatment planning by predicting response to neoadjuvant therapy in chemosensitive tumours, such as osteosarcoma, thus personalising treatment strategies. Additionally, radiomic features can be used to monitor disease progression and recurrence of malignant bone tumours more effectively than traditional imaging methods. Recent studies have demonstrated that integrating radiomics with clinical data enhances predictive models for patient outcomes.
