Detailed explanation-1: -Non-contrast computed tomography (NCCT) is deemed as the first choice for all stroke diagnosis due to its relative high speed, broad accessibility and cost-effectiveness compared with magnetic resonance imaging (MRI) and CT perfusion (CTP) [3, 4], especially in the setting of emergence department [5].
Detailed explanation-2: -A stroke diagnosis using a CT scan is ideal for identifying whether the stroke is hemorrhagic or ischemic. If there is blood in the skull due to a hemorrhage, a stroke CT scan can detect it immediately, ensuring this condition is treated the right way.
Detailed explanation-3: -A noncontrast head CT may identify the early signs of stroke, but most importantly will exclude intracerebral hemorrhage and lesions that might mimic acute ischemic stroke such as tumor or intracerebral hemorrhage.
