(A) Box plot of FDG SUV_max from malignant and benign vertebral compression fractures (VCFs). Bottom and top of each box are lower and upper quartiles. The band near middle of box is median. Extremes of lower and higher whiskers represent range of minimum and maximum values. *P<0.05, Wilcoxon signed-rank test. (B) Receiver operating characteristic (ROC) curve analysis was performed to calculate the optimal cutoff value of SUV_max for the differentiation between benignity and malignancy. Sensitivity and specificity changed with changes in the SUV_max. The SUV_max of the farthest point away from the chance line was 3.45.

Abbreviations: 18F-FDG, 2-[fluorine-18]-fluoro-2-deoxy-D-glucose; SUV_max, maximum standardized uptake value; AUC, area under the curve.
