Content Item Descriptions

Row 10

The nominal shear wave speed for the tissue of interest. How this nominal value is derived from the measurements in Row 25 is implementation dependent.

Rows 11-14

These values are a statistical characterization of shear wave speed measurements in Row 25 from which the value in Row 10 was derived.

Row 15

The nominal Elasticity for the tissue of interest. How this nominal value is derived from the measurements in Row 25 is implementation dependent.

Rows 16-19

These values are a statistical characterization of Elasticity measurements in Row 25 from which the value in Row 15 was derived.

Row 20

The nominal Shear Wave Dispersion Slope for the tissue of interest. How this nominal value is derived from the measurements in Row 25 is implementation dependent.

Rows 21-24

These values are a statistical characterization of Shear Wave Dispersion Slope measurements in Row 25 from which the value in Row 20 was derived.

Row 26

The identifier is used to distinguish the different measurement ROIs. For example, the identifier might be used as a column header when displaying the measurements from all the ROIs in a table.

Row 27

The specific location of a measurement, e.g. the specific segment of the liver, may be recorded here. If this row is absent, the measurement is presumed to be somewhere within the organ/tissue identified in Row 3.

Row 29

In Shear Wave Elastography, the Reference Measurement Group is used to record measured values for a reference region against which the measurements in Row 25 may be compared.

Row 30

A coded description of the location of the reference measurement. If this row is absent, the reference measurement is presumed to be some conventional location appropriate for the organ/tissue identified in Row 3. If the SCOORD in TID 5402 is present, that indicates the spatial location.
