A non-invasive computer-aided personalized diagnosis system for Osteopenia and Osteoporosis

Abstract

Background:

Osteoporosis is a common bone related disease that is characterized by a severe decrease in bone mineral density and an elevated risk of fracture. To achieve an effective disease management and fractures avoidance, the detection of the disease at its early stage, the Osteopenia stage, is extremely beneficial.

Methods:

For this purpose, this paper presents a non-invasive computer aided diagnosis system for disease’s screening using knee X-ray scans in its two basic stages (i.e., Osteopenia and Osteoporosis). Furthermore, a probabilistic diagnosis is produced for each scan, offering a personalized diagnosis that in turn indicates the severity of the disease, if exist, for each individual independently. Accordingly, the proposed methodology consists of three main steps: (1) the X-ray scans of three groups (i.e., normal, Osteopenia, and Osteoporosis) are pre-processed to improve the scans’ quality, and to serve the feature extraction and the construction of the model; (2) the pre-trained VGG16 model is used to identify the descriminative characteristics of each studied group that are then; at stage (3) fed to the SVM classifier to accomplish the diagnosis task, including the severity grading task.

Results:

Evaluating the proposed framework showed promising results with an average overall accuracy of 94.85%. In the groups base, the results were around 93.75%, 96.77%, and 100% for the normal group’s recall, F1-score, and precision, respectively. For the Osteopenia group, the results were around 93.95%, 100%, and 88.60% for F1-score, recall, and precision, respectively. Finally, the Osteoporosis group’s results achieved an average of 93.91%, 90%, and 98% for F1-score, recall, and precision, respectively.

Conclusion:

These results reflect the powerful ability of the proposed work especially that it could outperform the related efforts. Accordingly, these results encourage further analysis to extract more related medical insights for consequent assistance in the relevant healthcare diagnosis and treatment plans.
