Comparison of Diagnostic Accuracies of Different Imaging Modalities in AD. a
| Modality | Sensitivity | Specificity |
|---|---|---|
| CT | 80 (68-88) | 87 (78-93) |
| MRI | 83 (79-87) | 85 (80-89) |
| FDG-PET | 91 (86-94) | 85 (79-91) |
| rCBF-SPECT | 79 (72-85) | 84 (78-88) |
AD = Alzheimer’s disease; CT = computed tomography; MRI = magnetic resonance imaging; FDG-PET = [18F]fluorodeoxyglucose–positron emission tomography; rCBF-SPECT = regional cerebral blood flow–single photon emission computed tomography.
