MRI

• Fluid-attenuated inversion recovery (FLAIR) is the most sensitive MRI pulse sequence for the detection of SAH. SAH appears as high-intensity signal in normally low signal CSF spaces.
• 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.
• MR angiography may be useful in the evaluation of aneurysms and other vascular lesions that cause SAH.
