Siemens Software version syngo CT 2005C Filtering, Moving the Sampling Line, Delay of Injection

syngo Dynamic Evaluation

•Filtering

To reduce noise in the Time to Peak and Peak Enhance- ment image you can apply a smoothing filter. Filtering does not affect the evaluation of ROIs.

•Moving the Sampling Line

If you want to evaluate the enhancement values for a different point in time, move the sampling line in the horizontal direction.

You can display the tomographic image for the time marked by the sampling line as the top image in the tomo segment. To do that, double-click on the sam- pling line.

•Delay of Injection

You usually start the CT scans with contrast medium after a delay following contrast medium injection. You can have this off-set taken into account in calculation of the Time to Peak image and enhancement curves. The results then refer to the time of contrast medium administration (zero on the time scale).

➭Enter the delay from the start of injection of the con- trast to the start of the scan and confirm with the Enter key.
