Does this test definitively diagnose or rule out vascular TOS?

It seems people talk more about MRA/MRV or other radiography to see arteries/veins.

For those that have vascular TOS, can you share how you got a definitive diagnosis?

I just got the test - it came back normal for the most part. Except that when i put my arms straight up, the blood flow to the hands is completely cut off. The doc says I definitely don't have vascular TOS - but b/c my blood flow gets cut off when my arm are straight up-- it indicates that my 'thoracic outlet space" is smaller and that I may have a predisposition for TOS...neurogenic TOS.

Does anyone have any input or experience they can share...about the Doppler? Would really appreciate it....
