Values of Apparent Diffusion Coefficient and Lesion-to-Spinal Cord Signal Intensity in Diagnosing Solitary Pulmonary Lesions: Turbo Spin-Echo versus Echo-Planar Imaging Diffusion-Weighted Imaging

Table 3

Sensitivity and specificity of ADC and LSR at optimal cutoff values in differentiating malignant from benign solitary pulmonary lesions.

Parameters	AUC	Cutoff value	Sensitivity (%)	Specificity (%)	+LR (%)	-LR (%)
TSE
ADC (^-3 mm^2/s)	0.781	1.450	81.82	72.73	3.00	0.25
LSR	0.748	1.060	72.73	81.82	4.00	0.33
EPI
ADC (^-3 mm^2/s)	0.789	1.380	86.36	81.82	4.75	0.17
LSR	0.818	0.878	77.27	81.82	4.25	0.28

Note: AUC: area under the ROC curve; ADC: apparent diffusion coefficient; LSR: lesion-to-spinal cord signal intensity ratio; +LR: positive likelihood ratio; -LR: negative likelihood ratio.
