Table 2. Performance of soft tissue inflammation in pathogen detection.

Soft tissue inflammation	Sens [%]	Spec [%]	Acc [%]	PPV [%]	NPV [%]
Paravertebral infiltration	100.0	50.0	64.7	45.5	100.0
Epidural infiltration	40.0	83.3	70.6	50.0	76.9
Paravertebral abscess	40.0	90.9	75.0	66.7	76.9
Paravertebral infiltration >5 mm	100.0	62.5	73.5	52.6	100.0

Soft tissue inflammation was categorized into paravertebral infiltration, epidural infiltration, paravertebral abscess, and paravertebral infiltration > 5 mm. Sensitivities, specificities, accuracies, PPVs, and NPVs for successful pathogen detection by CT-guided biopsy are specified.
