Recent work has confirmed the diagnostic performance of pseudo-CT sequences for detecting osteolytic lesions. Their integration into whole body MRI (WB MRI) could transform the diagnostic approach to MM, by allowing a combined assessment of bone marrow involvement, tissue viability and osteolysis, during a single non-irradiating imaging examination. Since the preliminary work mentioned above, optimizations have been made to the pseudo-CT sequences, including the addition of deep learning (correcting noise in the images) and the correction of chemical shift artifact (linked to the coexistence of hydrated tissue and fatty tissue), which carry real hope of improving their diagnostic potential and accuracy.

Evaluation of the diagnostic performance of the different imaging protocols
The diagnostic performance of the different imaging protocols will be evaluated by analyzing the receptor efficiency function (ROC curve) and by estimating the Sensitivity (Se), Specificity (Sp), Positive Predictive Value (PPV), Negative Predictive Value (NPV) ) as well as the Predictive Accuracy (Acc) of the different imaging protocols.
Comparison of Sensitivity (Se) and Predictive Precision (Acc) of the different imaging protocols
McNemar test on paired data. The Gold Standard will be determined by a panel of independent experts based on all available imaging techniques.
