syngo Calcium Scoring

Prerequisites

To achieve standardization of the evaluation results

the image material must meet the following require-

ments:

• Only images of one patient must be loaded for

syngo Calcium Scoring evaluation.

• The scans must have been acquired without gantry

tilt (gantry tilt = 0).

• Only original image material must be used that

has neither been edited with 2D tools in the Viewing

task card e.g., Zoom&Pan nor with 3D tools in 3D

e.g., curved mode.

• Only image data sets with the same slice orientation

must be used.

• Only contiguously scanned and reconstructed

sequence or spiral data sets with identical slice

distances and identical thickness must be evaluated.

• The slices must have been scanned at different table

positions.

• The data capacity of the volume must not exceed

1024 images with a matrix size of 512 x 512 pixels.

• Only studies without contrast medium must be used.

Best Calcium Scoring results are achieved when

special scan protocols for image acquisition have been

used.

For this reason, the SOMATOM CT Scanners offer

several Calcium Scoring scan modes (for example:

“CaScoreSeq“ or “CaScoreRoutine“), which use the

advanced CT HeartView trigger method for scanning.
