While invasive methods provide the most accurate data, the Non-Invasive ICP Monitoring segment is forecasted to be the fastest-growing category, with a CAGR exceeding 7.9% through 2032. This growth in the Intracranial Pressure (ICP) Monitoring Market is driven by the demand for "zero-risk" diagnostics. Technologies such as Transcranial Doppler (TCD) Ultrasonography and Optic Nerve Sheath Diameter (ONSD) measurement are increasingly used as first-line screening tools.

In late 2025, regulatory approvals for non-invasive devices using optical sensors have accelerated market entry. Advanced imaging techniques, including MRI-based pressure estimation, are also gaining traction for routine follow-ups. These methods allow clinicians to assess brain compliance without surgical intervention, which is particularly vital for pediatric patients where avoiding sedation and surgery is a high priority.

The development of portable, non-invasive versions is also supporting specialized applications in defense and aerospace. These "space-medicine" inspired devices support mountaineers, soldiers, and pilots operating at extreme altitudes where invasive catheters are impractical. This expansion into non-clinical environments is creating a downstream market pull for miniaturized, battery-powered sensors that are now migrating into civilian emergency transport settings.
