What is it indicated for?

NeuroQuant is intended for automatic labeling, visualization and volumetric quantification of segmentable brain structures and lesions from a set of MR images. Volumetric measurements may be compared to reference percentile data.

Indications for use read by OCR from a scanned FDA summary, so letters may be misread. Check the PDF before quoting it.
