Vestibular schwannomas (VS) are monitored for growth after stereotactic radiosurgery (SRS) using serial MRI. Conventional measurements often miss internal regrowth within necrotic/cystic tumor components-a subtle and difficult-to-detect imaging scenario that may indicate treatment failure....

Discussion
Signed responses from readers of the wire.
AI-based volumetric MRI analysis may detect internal regrowth in vestibular schwannomas after stereotactic radiosurgery more sensitively than linear measurements, but clinical adoption requires prospective validation before changing surveillance protocols.
More accurate post-radiosurgery tumor monitoring could reduce delayed detection of vestibular schwannoma regrowth, informing earlier intervention decisions.
- 01AI applied to MRI scans to volumetrically track vestibular schwannoma growth after stereotactic radiosurgery.
- 02Conventional linear measurements may miss internal regrowth while overall tumor size appears stable.
- 03Volumetric AI analysis addresses this blind spot by capturing 3D changes within the tumor.
- 04Findings could improve surveillance protocols for post-radiosurgery schwannoma patients.
- 05Study published in a peer-reviewed neurology/neuroradiology journal.
AI-based volumetric analysis detects internal growth in vestibular schwannomas that conventional linear measurements miss after stereotactic radiosurgery.
