Explanation:
Detailed explanation-1: -CT. CT scan is almost always the first imaging modality used to assess patients with suspected intracranial hemorrhage.
Detailed explanation-2: -Brain MRI with DWI has the most sensitivity and specificity and is the best option to diagnose acute stroke. It is superior to NCCT to early detection of acute ischemic stroke; however, MRI/MRA may not always be available in all centers, and performing this modality is time-consuming.
