What Physicians Need to Know

Median Nerve Segmentation and Measurement
Clarius Median Nerve AI automatically identifies, segments, and measures the cross-sectional area of the median nerve in ultrasound images, primarily for carpal tunnel syndrome (CTS) assessments. This automation aims to reduce reliance on subjective manual interpretation and improve diagnostic precision.
Accuracy and Reliability
The AI model has demonstrated high accuracy in segmenting the median nerve, with some studies reporting a Dice Similarity Coefficient (DSC) of 0.922 and an Intersection over Union (IoU) of 0.855, indicating strong agreement with expert segmentations. AI measurements of the median nerve have shown high agreement with manual measurements, with an error of only 0.92 mm². The system has also been shown to be non-inferior to experienced ultrasound reviewers/clinicians for median nerve cross-sectional area measurements.
Workflow Efficiency
Clarius Median Nerve AI is designed to accelerate carpal tunnel diagnosis by automating identification and measurement, streamlining the workflow with auto-segmentation and one-tap documentation. This can save time and improve documentation.
Ease of Use and Learning Curve
The tool is described as intuitive and easy to learn, allowing even non-experts to produce reliable, surgical-grade data after minimal training. It guides novice users and enhances efficiency for experts, making ultrasound more accessible.
Quality Control Indicator
The AI model includes a built-in quality control indicator, segmenting the nerve only when a clear, perpendicular image free of anisotropy is achieved, which serves as a check for less experienced operators.
Mobile Notification System
Clarius handheld wireless ultrasound scanners connect to iOS and Android devices, enabling high-resolution ultrasound images to be viewed on a smartphone or tablet. This allows for point-of-care scanning and potentially mobile notifications through the app.
Physician Tip

Clarius Median Nerve AI can significantly enhance the efficiency and objectivity of carpal tunnel syndrome (CTS) assessments. Physicians can leverage this tool to automate median nerve identification and cross-sectional area measurements, reducing subjectivity and variability in diagnosis. This can lead to faster clinical decisions and improved patient satisfaction. The built-in quality control indicator helps ensure accurate measurements, even for less experienced users, making it a valuable tool for training and delegation to medical assistants for initial scans. Integrating this AI into your practice can also help track treatment response with consistently performed measurements. While the AI provides automated measurements, the physician retains responsibility for confirming the validity of these measurements based on standard practices and clinical judgment.

Clarius Median Nerve AI is integrated into the Clarius App software and is available with Clarius L20 HD3, L15 HD3, and L7 HD3 handheld ultrasound scanners. It is part of the broader Clarius AI portfolio, which includes other tools like MSK AI and T-Mode™ AI for anatomical learning and workflow enhancements. All Clarius AI models are available with a Clarius Membership or One-Time License and include specialized imaging presets, built-in patient reports, and integrated billing codes to streamline workflow.
