6. Enhancement Curve
As soon as you have defined an ROI, an enhancement
curve (time-density curve) is calculated and displayed
in the fourth segment. To facilitate identification, this
curve has the same color and numbering as the associ
-
ated ROI. The maximum CT-value of the ROI first drawn
is indicated by a dashed sampling line.
In the table, for each ROI, the following parameters are
given:
• Peak [HU]: Highest CT value detected in the ROI.
• Time to Peak [s]: Period of time in seconds from the
time when the first image was acquired (Delay = 0)
or the time when the contrast was injected
(Delay
> 0) to the time when the highest CT value is
reached in an ROI.
• Sample [HU]: CT value at the point of time (in sec)
where the vertical line is positioned on the enhance
-
ment curve.
Absolute/Relative Enhancement curve
The enhancement curves are displayed as absolute or
relative curves.
• The Absolute Enhancement curve displays the origi-
nal CT-value derived at every point in time during the
examination.
• The Relative Enhancement curve displays the varia-
tion of CT-values with reference to the CT-values in
the baseline image at every point in time.
