4 Working with Contrast Images
You can work with the contrast images by using the features in the frozen mode, such as
cine review, annotations, data storage or measurement. For details, refer to Section 11.4
Using Cine, Section 11.5 Annotations and Body Marks, 12 Managing Images/Data and the
relevant sections in the advanced user manual.
You can also get more information about blood flow characteristics through observing TIC
curves. TIC curve indicates the contrast agent intensity variation with duration. To make a
TIC analysis, you should position ROI (8 at most), and then make a detailed analysis of the
contrast agent intensity variation with duration.
Perform the following steps to make a TIC analysis.
1. Tap TIC in the frozen mode to enter the TIC analysis screen.
2. Position one or more ROI on the contrast image.
−
Tap Ellipse on the touch screen, position a ROI by performing an ellipse
measurement.
−
Tap Trace on the touch screen, position a ROI by performing an auto-trace
measurement.
Once you position a ROI, the corresponding TIC curve is displayed on the bottom,
colors of TIC curve and ROI are consistent.
As Figure 8-3 shows, all relevant parameters are displayed on the top right part of the
screen.
