Can MRI detect intracranial pressure?
The best threshold for detecting elevated intracranial pressure with MRI was a nerve sheath diameter of 5.82 mm, which had a sensitivity of 90%, specificity of 92%, and negative predictive value of 92%. A threshold of 5.30 mm had 100% sensitivity and negative predictive value but specificity of only 50%.
Does IIH show up on MRI?
While many MRI findings have been reported for IIH, except for optic nerve head protrusion and globe flattening, the majority of these signs of IIH on MRI are not helpful in differentiating between idiopathic and secondary causes of intracranial hypertension. IIH is a diagnosis of exclusion.

Can a CT scan detect intracranial hypertension?
CT scan findings may be normal or may show slit-like ventricles in patients with benign intracranial hypertension (pseudotumor cerebri). CT scanning is usually needed to exclude other causes of increased intracranial pressure, such as tumors.
Can a neurologist diagnose IIH?
Given the relatively small number of neuro-ophthalmology specialists in the US, it is incumbent upon neurologists to diagnose and manage IIH. Idiopathic intracranial hypertension (IIH) is a syndrome that involves headache as one of its primary symptoms, and papilledema is a finding that supports this diagnosis.
