Efficacy and Cost-Benefit Analysis of Magnetic Resonance Imaging in the Follow-Up of Soft Tissue Sarcomas of the Extremities and Trunk

Table 5

Sensitivity, specificity, and predictive values of MRI diagnostics for discovery of local recurrence. Suspected local recurrence is composed of striking (suspected recurrence) and uncertain (unable to exclude recurrence) findings. These values are explicitly broken down in square brackets; in round brackets are the results of the evaluation using this separation.

	Tumor status: positive	Tumor status: negative	Sum of lines	Predictive values
Suspected local recurrence	68 [58 + 10]	145 [34 + 111]	213 [92 + 121]	Positive: 32% (63%)
Exclusion of local recurrence	0	1186	1186	Negative: 100%
Sum of columns	68	1331	1399
Sensitivity/specificity	Sensitivity: 100% (85%)	Specificity: 89% (89%)
