Table 2:

Sensitivity of MR imaging relative to intraoperative findings for soft tissue and ligamentous structures in the subdental cervical spine

Structure	No. Injured at Surgery	N	Sensitivity (%)
Anterior longitudinal ligament	14	18	71
Disk	15	18	93
Posterior longitudinal ligament	15	18	93
Vertebral body	6	18	100
Posterior osseous structures	22	77	45
Facet capsules	22	26	86
Ligamentum flavum	6	14	67
Interspinous soft tissues	6	14	100

Note:—Sensitivity here is defined as the proportion of injuries at surgery that were abnormal on MR imaging: that is, (True-positive)/(True-positive + False-negative).
