Diagnostic Significance of 18F-FDG PET/CT Imaging Coupled with Magnetic Resonance Imaging of the Entire Body for Bone Metastases

Table 3

MR whole-body diffusion imaging and their combined examination techniques were examined to determine the diagnostic usefulness of 18F-FDG PET/CT images.

Diagnosis way	AUC (95%CI)	Cut-off value	Sensitivity	Specificity
18 F - FDG PET/CT imaging	0.747 (0.613–0.857)	0.734	(87/97), 89.69%	(26/39), 66.67%
Magnetic resonance whole-body diffusion imaging	0.724 (0.577–0.832)	0.704	(85/97), 87.63%	(29/39) 74.36%
Two combined	0.856 (0.691–0.943)	0.890	(95/97), 97.93%	(36/39) 92.31%
χ ^2-value	3.883	-	6.917	3.912
