AI Technical Summary

Technical Problem

Existing technologies for diagnosing bone metastases suffer from limitations in single-modality diagnostic accuracy, lack of prognostic assessment methods, reliance on human experience for lesion localization, imprecise lesion segmentation and classification, and a disconnect between diagnosis and prognosis.

Method used

A bone metastasis diagnosis and prognostic assessment system based on multimodal deep learning is adopted. Through data acquisition and preprocessing modules, bone anatomy partitioning modules, dual-stream feature extraction and fusion modules, and diagnostic modules, the system integrates the functional information of radionuclide bone scintigraphy and the anatomical information of CT images to achieve accurate detection, segmentation and classification of lesions, and combines clinical data for prognostic prediction.

Benefits of technology

It improves the accuracy of bone metastasis diagnosis, reduces the false positive rate, provides individualized prognostic assessment, supports clinical decision-making, realizes data integration from imaging to prognosis, and outputs quantitative survival prediction results.
