This appears to be correct; however, for an end diastolic velocity of 150 cm/sec to have a high clinical utility, values less than 150 cm/sec should be helpful in identifying arteries that lack critical stenosis. Figure 3 of Olin and colleagues' report shows that this is clearly not the case ([1]). Several investigators have shown that end diastolic velocity correlates inversely with...
