Sep. 15, 2025 —ScanLabMR has introduced its Signal-to-Noise Ratio (SNR) calculator. This feature gives MRI technologists, radiologists and educators a smarter, more reliable way to understand and optimize image quality.
Currently available SNR calculators provided by MRI manufacturers often fall short, offering only partial calculations and measurements that fail to capture all the complex variables affecting SNR. In particular, these tools cannot account for the composition of various tissues within the imaging slice in real time—a critical limitation that leads to an overall misunderstanding of SNR in clinical practice.
ScanLab’s breakthrough SNR Calculator overcomes these limitations by prospectively calculating the true SNR outcome based on the user’s prescribed slices. This allows for the creation of quantitative SNR values that account for all parameter adjustments and physical factors present within the MRI environment.
The competitive advantage lies in its predictive power: users can estimate SNR outcomes before performing a scan. This unique capability allows students and professionals to explore parameter changes, test protocol variations, and understand trade-offs between image quality and scan time—all in a safe, risk-free learning environment.
“Accurate SNR modeling is a crucial step toward advancing MRI education and clinical practice, because it has never been done accurately before,” said Matthew Hayes, President and Creator of ScanLabMR. “We believe every user should have access to this level of insight without worrying about whether they can afford it. That’s why we’re including the SNR Calculator in all existing licenses at no extra charge. Our mission is to give MRI professionals the tools they need to take ownership of image optimization and deliver the highest quality of care.”
By making the SNR Calculator freely available to all current users, ScanLab reinforces its commitment to ensuring that cutting-edge technology for education and training remains accessible to students, technologists, and radiologists worldwide.
This new tool also strengthens ScanLab’s position as the go-to resource for MRI education and simulation, offering institutions, hospitals, and training programs an unrivaled platform for teaching and skill development. By enabling learners to experiment with protocol adjustments virtually, ScanLab empowers MRI professionals to move beyond vendor presets and take control of image optimization.
Key Benefits of the ScanLab SNR Calculator:
- More accurate than manufacturer calculators
- Predictive insight into SNR outcomes without running a scan
- Educational value for students and technologists learning the impact of protocol changes
- Competitive edge for institutions training the next generation of MRI professionals
