Measurement of tumor volume is a key component in estimating tumor burden in patients with NF1, NF2, and schwannomatosis. Linear measurements are often used as a surrogate for tumor volume, but for irregularly shaped tumors that grow in non-uniform ways, linear measurements are often inaccurate and unreliable, and may vary considerably between scans and reviewers.

Semi-automated volumetric techniques improve tumor measurement and longitudinal tracking of tumor growth but are not widely available to NF clinics.

The NF Tumor Metrics Service provides reliable volumetric analyses of lesions on MR images to neurofibromatosis clinics nation- and worldwide. Our web-based systems ensure easy access to imaging results—anywhere, anytime—with very reasonable turnaround time.
