CT Scan Brain Normal Vs Ischemic Stroke Images | Non-Contrast Hyperacute/Acute/Chronic Infarction
*Cases:
Intro - 0:00
Ischemic Stroke- Immediate (Hyperdense MCA Sign) - 0:12
Hyperacute - 4:29
Acute - 7:48
Subacute - 9:35
Chronic - 10:56
Hyperacute:
Loss of Gray-white matter differentiation
Hypodense cortex
Gyral effacement - Flattening of gyri
Disappearance of sulci
Acute:
Hypodense areas
Cytotoxic cerebral edema (Swelling)
Mass effect
Midline Shift
Sulcal Disappearance
Subacute:
Reduction of swelling
CT Fogging Effect- Hypodense areas become isodense
Normal Appearance
Cortical petechial hyperdense hemorrhages
Chronic:
Gliosis - Hypodense areas
Encephalomalacia due to liquefactive necrosis - hypodense
The hypodense areas have similar density to CSF
Ex vacuo dilatation of the lateral ventricle adjacent to the chronic infarct
