syngo Calcium Scoring
2. Evaluating Coronary Lesions
– Screening loaded images for coronary lesions with
significantly increased calcification.
– Marking the detected lesions in the tomogram.
– Editing the coronary lesions in 3D or 2D.
2.1. Screening
After loading the CT images, you can
– scroll through
–zoom
– change window for better display.
In the images of your Calcium Scoring examination all
structures with calcium values above the set threshold
value are displayed in color.
Before you start to identify coronary arteries and spe-
cific coronary lesions you should optimize the thresh-
old settings.
Initially, the threshold value is set to a default value of
130 HU which is an empirical value. However, you can
freely configure this value yourself.
Hint: If you change the threshold value during Calcium
Scoring evaluation you will lose all the evaluation
results you have obtained so far.
If you have already performed a Calcium Scoring eval-
uation for a particular patient and then changed the
threshold values, those evaluation results are no
longer valid. You will then have to repeat the Calcium
Scoring evaluation for that patient.
By browsing through the axial image stack and viewing
the MIP Thin, MIP or the MPR reconstruction, you can
quickly locate suspected calcification in any of the 4
major coronary arteries.
