From Dr. Sclafani himself . . . here's what I need first:
1. transverse doppler of the IJV in J1, J2 and J3 during inspiration in the supine and sitting positions. Measure color and waveform at each site in both positions. Look for reflux and looking for no flow.
2. Longitudinal doppler imaging of the vertebral veins during inspiration in supine and sitting positions looking for reflux by color and waveform
3. B-mode ultrasound to look for abnormal valves, septae, webs
4. Transcranial color doppler and waveforms to look at the deep cerebral veins for reflux
5. measure cross sectional area of jugular vein in the spot where it is largest in supine and measure same cross sectional area in the same location while sitting up. Subtract sitting csa from supine CSA.
DOPPLER DIAGNOSTIC OF CCSVI IF TWO OF FOLLOWING PRESENT
1. REFLUX IN IJV OR VERTEBRALS
2. NO FLOW IN JUGULAR
3. REFLUX IN DEEP CEREBRAL VEINS
4. CSA SUPINE MINUS CSA SITTING IS NEGATIVE NUMBER
5. BMODE SHOWS STENOSIS, WEBS, ABNORMAL VALVES ETC
