From: Dixon chemical shift MR sequences for demonstrating of bone marrow vertebral metastasis

Modality  + CUI  − CUI
Value Rating (for case finding) Value Rating (for screening)
T2 Dixon (WO) and T2 (OP) 0.783 Good 0.375 Poor
T1 post-contrast Dixon (WO) 0.925 Excellent 0.636 Fair
T1 and T2 Dixon (FO) 0.894 Excellent 0.553 Fair
