What Physicians Need to Know

DICOM Support & Standards
AI-Rad Companion (Musculoskeletal) processes previously acquired Computed Tomography (CT) DICOM images. It conforms to the DICOM 2016a Standard and supports network services through teamplay Images and teamplay Receiver. The system can store result DICOM data via teamplay Images and teamplay Receiver to a target node. Reports are generated in human and machine-readable formats, including DICOM structured report (SR) format (TID 1500 for applicable content).
PACS Integration Method
The tool is designed for full integration into the image interpretation workflow, providing results in various data formats for advanced integration, such as direct inclusion in reporting templates. The AI-Rad Companion with Notifier allows radiologists to review AI results independently of PACS limitations. Structured DICOM SR outputs can flow into PACS, RIS, or syngo carbon archives, and results can be transferred to PACS based on configuration. It integrates seamlessly into existing clinical workflows and imaging infrastructure.
Reading Room Workflow Impact
AI-Rad Companion (Musculoskeletal) aims to reduce the burden of basic repetitive tasks and may increase diagnostic precision by providing automatic post-processing of imaging datasets. It automates routine workflows with high case volumes, supporting interpretation by automatically providing results for review, confirmation, and inclusion in the final report. This can lead to increased precision, faster workflows, and reduced cognitive load by streamlining and standardizing reporting. It can also identify abnormalities that might otherwise go unnoticed.
AI Model Architecture (deep learning approach)
The tool utilizes deep learning algorithms, specifically a 3D Deep Image-to-Image network for organ segmentation. The network architecture follows a symmetric convolutional encoder-decoder design, with all blocks consisting of 3D convolutional and bilinear upscaling layers. The algorithms are trained, tested, and validated against extensive and diverse clinical datasets.
FDA Clearance Pathway (510k/De Novo)
AI-Rad Companion (Musculoskeletal) received FDA clearance via the 510(k) pathway. The initial clearance (K193267) was on March 16, 2020, and an enhanced version (K222361) with an improved AI algorithm was cleared on October 20, 2022. It is classified as a Class II device.
Supported Modalities (CT/MRI/X-ray/US)
For the Musculoskeletal module, the tool specifically processes Computed Tomography (CT) DICOM images. The broader AI-Rad Companion family supports multi-modality imaging, including CT, MRI, and X-ray.
Sensitivity & Specificity Data
Performance testing for AI-Rad Companion (Musculoskeletal) was conducted on 140 subjects, demonstrating equivalent performance compared to a reference device. A retrospective study evaluating the AI algorithm for vertebral body alterations on chest CT scans reported a sensitivity of 47.37% and a specificity of 63.87%, suggesting its utility as an auxiliary diagnostic method for dorsal spine fractures.
RSNA/ACR Validation
Siemens Healthineers presented the AI-Rad Companion Chest CT at the 2018 Radiological Society of North America (RSNA) annual meeting. While the ACR Data Science Institute (DSI) collaborates on developing, evaluating, validating, and monitoring AI algorithms, specific validation of AI-Rad Companion Musculoskeletal by RSNA/ACR is not explicitly detailed in the provided information. The algorithms are, however, trained and validated against extensive clinical datasets.
Physician Tip

Leverage AI-Rad Companion (Musculoskeletal) to automate repetitive tasks like vertebral segmentation and measurement on CT images, freeing up time for more complex diagnostic challenges. Integrate the AI-generated structured reports directly into your PACS and reporting templates for a streamlined workflow and enhanced consistency. Be aware that while the tool provides valuable quantitative and qualitative analysis, especially for spine evaluation, it serves as an auxiliary diagnostic method. Always review AI findings in conjunction with the original images and your clinical expertise, particularly considering the reported sensitivity and specificity for specific findings like vertebral body alterations. The tool's ability to highlight potentially overlooked abnormalities can act as a valuable safety net.

AI-Rad Companion (Musculoskeletal) is designed for seamless integration into existing radiology IT environments. It operates as a cloud-based application, deployed via the teamplay digital health platform, which facilitates regular updates and integration of new offerings. It communicates using DICOM standards (2016a, TID 1500 for SRs) and integrates with PACS, RIS, and syngo carbon archives. The 'Notifier' feature allows radiologists to access AI results even with PACS limitations, ensuring flexibility in diverse hospital infrastructures. Both cloud and on-premise 'edge' deployment options are supported.
