In a prior version of this Context Group, the code LN: 11726-7 was specified for Peak Velocity. This has been corrected to be Peak Systolic Velocity. Some applications might continue to send code LN: 11726-7 instead of LN: 20351-3 for Peak Velocity. Applications that need to encode peak velocity without pre-coordinating the phase can use LN: 20355-4 Peak Blood Velocity.
In a prior version of this Context Group, the code LN: 20352-1 was specified for Mean Velocity. This has been corrected to be Time Averaged Mean Velocity. Some applications might continue to send code LN: 20352-1 instead of LN: 11692-1 for Time Averaged Peak Velocity.
