syngo.CT CaScoring
Overview
syngo.CT CaScoring is an advanced image analysis software package developed by Siemens Medical Solutions USA, designed to support physicians in the evaluation and documentation of calcified coronary lesions from Computed Tomography (CT) data sets. This software allows for quick quantification and accurate visualization of calcified coronary lesions, including the number of lesions, volume, calcium mass, and the Agatston Score. It can assess plaque burden in total or for individual main coronary arteries (RCA, LM, LAD, CX).
The tool is integrated within the syngo.via multimodality reading solution, which operates on a client-server platform, providing a comprehensive environment for advanced visualization, measurement, and evaluation of CT images. syngo.CT CaScoring utilizes standard or low-dose spiral or sequential CT scanning data sets. It features automatic highlighting of coronary calcifications and allows for user modification of the default threshold (130 HU) for score calculation. The software also provides an immediate comparison of the patient’s score to a healthy reference group, presenting it in a percentile graph and calculating the patient’s ‘Coronary Age’. It supports the creation of detailed paper reports that can include calcium scoring data, user-documented images, and relevant clinical information.

What Physicians Need to Know
syngo.CT CaScoring provides crucial quantitative data, including Agatston, volume, and mass scores, essential for assessing atherosclerotic coronary heart disease risk. The automatic highlighting and 3D segmentation features enhance efficiency and accuracy in identifying and quantifying lesions. The 'Coronary Age' feature is a valuable tool for patient communication, offering an intuitive understanding of their coronary health relative to a healthy population. Utilize the prognostic indicators to guide primary prevention strategies and reclassify cardiovascular risk, informing appropriate treatment decisions. Remember that the physician is responsible for correctly assigning lesions to their respective coronary arteries.
syngo.CT CaScoring is an integral component of the Siemens Healthineers CT Cardio-Vascular Engine, alongside applications like syngo.CT Cardiac Function, syngo.CT Coronary Analysis, and syngo.CT Vascular Analysis. It seamlessly integrates with syngo.via, a comprehensive software solution that supports the entire workflow from case preparation to results sharing, including viewing, manipulating, communicating, and storing medical images. The software facilitates the generation of detailed reports in various formats such as HTML, RTF, PDF, JPEG, and MS Word.

What the Web Says
syngo.CT CaScoring is a software package from Siemens Healthineers designed to quantify and visualize calcified coronary lesions from CT data. It supports physicians in evaluating and documenting coronary artery calcifications, which are a risk factor for coronary artery disease. The software calculates various scores, including the Agatston equivalent score, volume score, and calcium mass, and compares the patient's score to a healthy reference group. Recent studies suggest that the AI-powered version of syngo.CT CaScoring can significantly improve workflow efficiency and achieve accuracy comparable to radiologists, especially when used in a semi-automatic mode with expert review.
Overall: PositiveStrengths
- Quick quantification and accurate visualization of calcified coronary lesions.
- Calculates Agatston, volume, and mass scores, and provides a percentile graph for comparison to healthy reference groups.
- Automatic highlighting of coronary calcifications with customizable thresholds.
- Can significantly reduce evaluation time, especially with AI-powered automatic scoring.
- High accuracy in identifying and quantifying coronary artery calcium, comparable to manual expert review.
- Supports standardized image creation and reporting for clinical routine.
Limitations
- Optimal results often recommend a semi-automatic approach with physician review to minimize potential errors.
- Virtual non-contrast (VNC) images should not be used for scoring as they can lead to incorrect results.
- Requires specific slice thickness and increment for Agatston equivalent scores.
- Accuracy of measurements is primarily determined by the quality of the image data.
- Some studies indicate a slight tendency for AI to underestimate extremely high Agatston scores (>1000).
- Functionality for scoring lesions manually by drawing a region of interest (ROI) is only available for data from Siemens Healthineers CT scanners.
