Key Findings

• SyMRI detected intracranial complications of SAH similarly to conventional MRI.
• SyMRI acquisitions have quality metrics comparable to conventional MRI.
• SyMRI acquisition time is shorter compared to conventional MRI.

The two techniques performed well in detecting ischaemic lesions and extra-axial collections (kappa = 0.80 and 0.88 respectively) and were good for the detection of hydrocephalus (kappa = 0.69). No significant differences were detected in the number of ischaemic lesions (p=0.31) or in the Evans index (p=0.11). 

The WMv and CSFv measures were also similar (p=0.18 and p=0.94, respectively), as well as the volume of ischaemic lesions (p=0.79). The SyMRI acquisition time was shorter compared to conventional MRI regardless of the number of sections (32% and 6% time reduction for 4 or 3 mm section thickness, respectively).
