Figure 3From: Use of T2-weighted magnetic resonance imaging of the optic nerve sheath to detect raised intracranial pressureROC curves for ONSD and OND with respect to raised ICP. 'Raised ICP' is defined as an ICP above 20 mmHg identified during T2-weighted magnetic resonance imaging. ICP, intracranial pressure; OND, optic nerve diameter; ONSD, optic nerve sheath diameter; ROC, receiver operating characteristic.Back to article page
