How Effective Are Noninvasive Tests for Diagnosing Malignant Peripheral Nerve Sheath Tumors in Patients with Neurofibromatosis Type 1? Diagnosing MPNST in NF1 Patients

Table 3

Areas under the curve (AUC) and associated confidence intervals (CI) from receiver operating characteristic curves for SUV_max, SUV_peak, and tumor-to-liver ratio (TLR). Using these present data, cutoff points were selected to optimize sensitivity and specificity. Our cutoff point for SUV_max differed slightly from that established in the previous literature, so the sensitivity and specificity of the previous cutoff point were calculated using the present data.

	AUC	CI	Cutoff	Sensitivity	Specificity
SUVmax	0.85	0.73–0.96	5.3	91.2	70.0
SUVpeak	0.83	0.71–0.96	4.5	91.7	65.0
TLR	0.84	0.71–0.97	3.0	91.3	68.4
