What Physicians Need to Know

DICOM Support & Standards
AI-Rad Companion conforms to the DICOM 2016a Standard, supporting network services through teamplay Images and teamplay Receiver. It receives input DICOM data, stores result DICOM data, and can export segmentations and contours as DICOM RTSTRUCT. The tool generates standardized, reproducible, and quantitative reports in DICOM SC format and is seamlessly integrated into existing clinical workflows as a DICOM-compliant solution.
PACS Integration Method
The solution communicates indirectly with other DICOM nodes via teamplay Images and teamplay Receiver. Results can be transferred to PACS based on configuration, and the AI-Rad Companion with Notifier allows radiologists to review AI results independently of PACS limitations. Images and supporting information, including DICOM SC format reports, are automatically made available in the PACS for clinical routine.
Reading Room Workflow Impact
AI-Rad Companion supports physicians' reading workflow by automating post-processing and reducing the burden of repetitive tasks, potentially increasing diagnostic precision and speeding up the workflow. It seamlessly integrates into reading and reporting workflows, offering automated measurements and DICOM structured reports. The system automatically highlights abnormalities, segments anatomies, compares results to reference values, and provides AI results for review and inclusion in reports. Early studies showed radiologists could annotate chest CTs up to 25% faster without compromising accuracy. It also acts as a diagnostic aid, helping to alleviate potentially missed findings and providing confirmatory evidence.
AI Model Architecture (deep learning approach)
The AI-Rad Companion family leverages deep learning algorithms. These algorithms are trained on extensive clinical datasets and meticulously annotated by qualified clinical specialists to provide segmentation, measurement, and highlighting of key anatomical structures, supporting quantitative and qualitative analysis.
Processing Speed (per study)
The AI-Rad Companion significantly reduces processing time, with automated segmentation of the prostate on MRI images taking seconds rather than minutes. Similarly, automated contouring of anatomical structures in CT or MRI scans can be completed in a matter of seconds, leading to a noteworthy reduction in turnaround time for tasks like radiation therapy planning.
FDA Clearance Pathway (510k/De Novo)
Multiple modules of the AI-Rad Companion have received FDA 510(k) clearance. This includes the AI-Rad Companion Engine (K183272), Pulmonary (K183271), and Cardiovascular (K183268) modules for Chest CT (cleared September 2019). The AI-Rad Companion Brain MR for Morphometry Analysis and AI-Rad Companion Prostate MR for Biopsy Support received clearance in August 2020. AI-Rad Companion Organs RT also received 510(k) clearance in November 2020. The entire AI-Rad Companion family is CE-marked.
Supported Modalities (CT/MRI/X-ray/US)
The AI-Rad Companion supports a multi-modality approach: CT (e.g., Chest CT, Organs RT for head and neck, thorax, abdomen, pelvis), MRI (e.g., Brain MR for Morphometry Analysis, Prostate MR for Biopsy Support), and X-ray (e.g., Chest X-ray). While the AI-Rad Companion processes MRI for prostate biopsy support, the annotated MRI images can be used for fusion with Ultrasound (US) images during biopsy.
Sensitivity & Specificity Data
For AI-Rad Companion Chest X-ray, studies demonstrate high accuracy with AUC of 95u201399% for target radiographic findings. Specific data includes: Pulmonary Lesions (AI sensitivity 85.5% vs. reader 35.5%; one study showed 0.83 sensitivity and 0.83 specificity at confidence score u2265 6), Atelectasis (AI sensitivity improved by 35.5%), Pleural Effusion (AI sensitivity 95.7% vs. reader 83.4%), and Pneumothorax (AI sensitivity 78.7% vs. average reader 30%, with comparable specificity of 97% vs. 99.7%). High Negative Predictive Values (NPV) are observed across findings, though superior sensitivity can sometimes be accompanied by higher false-detection rates. For Chest CT, in 14% of analyzed cases, the software provided additional clinically valuable information not initially noticed.
RSNA/ACR Validation
Siemens Healthineers has a strong presence and validation through major radiological societies. AI-Rad Companion Chest CT was presented at the 2018 RSNA annual meeting, and the MRI assistants (Brain MR and Prostate MR) were introduced at the 2019 RSNA annual meeting. The FDA clearance for AI-Rad Companion Organs RT was announced during the virtual 106th RSNA (2020). Siemens Healthineers partners with the ACR for end-user education and transparency, and its AI solutions are listed on the ACR Data Science Instituteu00ae AI Central database.
Physician Tip

Leverage AI-Rad Companion to offload repetitive tasks like segmentation and measurement, allowing more focus on complex cases requiring human interpretation. Utilize the automated structured reports and highlighted abnormalities for increased diagnostic precision and efficiency in the reading room. Be aware of the specific sensitivity and specificity data for each module, especially the potential for higher false-detection rates in some Chest X-ray findings, and use the high Negative Predictive Values to reinforce confidence in negative findings. Integrate the AI results concurrently with original images for a comprehensive review.

AI-Rad Companion is a cloud-based solution deployed via the teamplay digital health platform, ensuring secure data transfer and GDPR compliance. It offers seamless integration into existing clinical workflows and PACS through DICOM standards, including DICOM SC and RTSTRUCT. The platform facilitates automatic updates and upgrades of algorithms, and it is designed to be vendor-neutral, capable of analyzing image data from various CT and MRI manufacturers.
