MSKai

The MSKai device is a Class II Medical Image Management and Processing System designed to provide qualitative viewing and quantitative lumbar spine measurements from T2-weighted MRI. Its functionality relies on image identification and post-processing algorithms, validated through non-clinical performance testing which demonstrated accuracy for anatomical segmentations and measurements, affirming its safety and effectiveness for assisting medical professionals.

The MSKai device is categorized as a Class II Medical Image Management and Processing System, and following a comprehensive review, it was deemed substantially equivalent for its intended indications, permitting its marketing under general regulatory controls. These controls ensure ongoing compliance with requirements such as annual registration, device listing, adherence to good manufacturing practices, specific labeling, and strict prohibitions against misbranding or adulteration, all while conforming to the Quality System regulation. The MSKai software functions as an advanced tool for image identification, post-processing, measurement, and reporting, specifically designed to provide qualitative viewing and quantitative spine measurements from pre-acquired T2-weighted DICOM lumbar spine MRI images. While it is not intended for diagnostic purposes, it significantly aids physicians, radiologists, and other medical professionals in their review, evaluation, and analysis. Rigorous non-clinical performance testing, including software design verification, a standalone performance assessment study, and cybersecurity evaluations, confirmed the software's accuracy for anatomical segmentations and measurements within specified margins, thereby affirming its safety and effectiveness.

• Q1. Given it is not a diagnostic device, how is the MSKai intended to integrate into clinical workflows without leading to misinterpretation or over-reliance by physicians?; What are the specific "defined margins" for accuracy of anatomical segmentations and measurements, and how do these compare to inter-reader variability or established clinical benchmarks?; Beyond general "cybersecurity evaluations," what specific vulnerabilities were tested, and what detailed measures are in place to protect patient data managed by the system?; What types of T2-weighted DICOM lumbar spine MRI images (e.g., specific sequences, field strengths, patient populations) were used in the non-clinical performance testing, and does the device perform consistently across such variations?; Are there plans for post-market surveillance or clinical validation studies to further assess the device's utility and impact on patient outcomes or diagnostic efficiency in real-world settings?
