I am from China, 25 years old, and I dunno if I have been suffering this disease or not, perhaps only further diagnosises could tell.

This is my TCD report,(transcranial Doppler ultrasonography ) in which shows some anomaly of blood moving speed in some vessel, esp in Siphon, which seemed highly related to MoyaMoya.

If any one knows how to understand the data from the report, please send message to tell me. Thank you!

Left     Depth      Vm      Vs      Vd      PI      RI
(2MHz Occipital)                                    
BA prox.     72      -30      -47      -21      0.79      0.55
VA      58      -32      -48      -22      0.75      0.54

(2MHz Temporal)                                    
MCA      56      62      99      44      0.91      0.56

VA      58      -31      -45      -21      0.73      0.53
(2MHz Orbital)                                    
Siphon     64      -37      -62      -22      1.00      0.64
(2MHz Temporal)                                    
MCA     54      68      112      46      0.98      0.59
ACA      68      -36      -53      -30      0.57      0.44
PCA-P1      68      35      52      26      0.71      0.49    

Doppler spectral patterns are normal.

Conclusion:
1, velocities in BA and RACA decreased.
2, Velocities in LCS(Siphon) and RMCA increased.

Since you have had fainting episodes, might be a good idea to get a second opinion from a neurosurgeon who specializes in Moyamoya
