Patient profiles, examinations, and diagnoses
| Patient No./Age (y)/Sex | Delay between Pre- and Post-Acetazolamide 128I-IMP SPECT (d)* | Diagnosis† |
|---|---|---|
| 1/68/M | 7 | Right ICA severe stenosis at MRA and DSA |
| 2/63/M | 3 | Right ICA severe stenosis (90%) and left ICA stenosis (40%) at MRA and DSA |
| 3/48/M | 4 | Right MCA (M1) occulusion with collateral circulation at DSA |
| 4/51M | 3 | TIA, normal findings at MR imaging and SPECT |
| 5/53/F | 8 | Right ICA occulsion, left ICA stenosis, left ACA occulsion at DSA |
| 6/69/F | 7 | Bilateral mild ICA stenosis with lacunar infarctions at MRA and MR imaging |
| 7/57/F | 7 | Dizziness, normal flow and perfusion at MRA and SPECT |
| 8/55/M | 4 | Right ICA, MCA, and ACA stenosis at MRA; decreased perfusion at SPECT |
| 9/69/M | 4 | Right ICA stenosis at MRA, mildly decreased perfusion at SPECT |
* Both pre- and post-acetazolamide FAIR studies were performed on the day of post-acetazolamide 123I-IMP SPECT.
† ACA indicates anterior cerebral artery; DSA, digital subtraction angiography; ICA, internal carotid artery; MCA, middle cerebral artery; MRA, magnetic resonance angiography; and TIA, transient ischemic attack.
