TID 3508 Gradient Measurement

The Gradient Measurement Template consists of a CONTAINER, with an acquisition context of the measurement anatomic site, and containing the gradient measurement. This implies that the name of the measurement is effectively post-coordinated from the measurement name, the Hemodynamic Measurement Group container (procedure phase) name, and the acquisition context (finding site) value.

Content Item Descriptions

Row 5

Is used to encode the gradient measurements. Uses TID 300 “Measurement” for the Content Item structure of the measurements. That Template allows an INFERRED FROM relationship to other numeric measurements used in the computation or derivation of the current measurement. In the case of a gradient measurement, the pressure measurements at the distal and proximal locations may thus be explicitly conveyed.
