Fig 2. With the cutoff value derived from ROC analysis, the fat-signal fraction could be used to differentiate symptomatic myeloma from asymptomatic myeloma with 75% sensitivity and 80.2% specificity.

BMPC% for symptomatic myeloma showed 66.7% sensitivity and 72.7% specificity, which resulted in an insignificant contributor to discriminate symptomatic myeloma from asymptomatic myeloma. BM, BMPC%; B2, β₂-microglobulin; FSF, fat-signal fraction.
