What is BTI RADS 2.0 ?
This a machine-learning-based approach to distinguish benign from malignant focal bone lesions. The algorithm was developed on a 1114 patient cohort and yielded high performance for the benign/malignant differentiation with multimodal imaging, CT/radiographs only and an MRI only approaches (F1 score=0.80). This algorithm led to proposing the Bone Tumor Imaging Reporting And Data System (BTI-RADS) v.2.0 with increasing malignancy rates among classes from 0%, to 11%, to 42% to 89%.Prerequisites
This classification was tested on patient with solitary bone tumor with imaging evaluation centered on a focal bone lesion using MRI with contrast injection and with CT or conventionnal radiographs (i.e. radiographs were not accepted for spinal or pelvic lesions). The classification was NOT tested on soft tissue tumors, known multifocal bone lesion (i.e. multifocal metastatic disease or systemic conditions), and lesions previously treated surgically or by adjuvant therapy.Give it a try with the Calculator.
