Reference documentation and conspicuity of proved lesions in positive CT examinations with imaging findings corresponding to cause of acute neurologic deficit (n = 42)
| Target Diagnosis | No. of Imaging Findings with Target Diagnosis | No. with Reference Criterion (Nonexclusive List) | Ranking of Conspicuity Scoresa (Mean) (SD) |
|---|---|---|---|
| Infarct | 29 | Clinical confirmation of corresponding deficit = 29 | 2.10 (0.76) |
| Progression/confirmation on another imaging study = 23 | |||
| Confirmation at surgery = 0 | |||
| Mass | 25 | Clinical confirmation of corresponding deficit = 22 Progression/confirmation on another imaging study = 21 Confirmation at surgery = 2 | 2.80 (0.70) |
| Extra-axial hemorrhage | 10 | Clinical confirmation of corresponding deficit = 10 Progression/confirmation on another imaging study = 3 Confirmation at surgery = 0 | 2.60 (0.66) |
| Intra-axial hemorrhage | 6 | Clinical confirmation of corresponding deficit = 6 Progression/confirmation on another imaging study = 2 Confirmation at surgery = 0 | 2.67 (0.47) |
↵a Please see Materials and Methods. In brief, conspicuity scores: 1, minimally evident; 2, subtle; 3, distinct focal abnormality; 4, obvious.
