Overview

MRI

MRI may indicated in patients with subarachnoid hemorrhage if no lesion were found on prior angiography. Disadvantage of performing MRI in patients with subarachnoid hemorrhage may include:

Higher cost
Lower availability
Longer study time make it less optimal for detecting SAH. In addition
Not being sensitive for detection of subarachnoid hemorrhage within the first 48 hours

T2- and T2*-weighted images can potentially demonstrate SAH as low signal intensity in normally high-signal subarachnoid spaces. On T1-weighted images, acute SAH may appear as intermediate- or high-intensity signal in the subarachnoid space
