Sir can u clarify does blood appear hyper dense in both CT and MRI?

[@DrSamsImagingLibrary]

On CT Scan: Acute Hemorrhage (within hours) Hyperdense (bright white) on non-contrast CT images. Subacute Hemorrhage (days to a week) May start to appear isodense (same density as surrounding tissue) due to clot retraction and hemoglobin breakdown. Chronic Hemorrhage (weeks to months) Hypodense (dark grey to black) relative to brain tissue. Sometimes calcifications can occur in chronic hemorrhages, appearing hyperdense. On MRI: T1-Weighted Images: Acute Hemorrhage (within hours): Generally isointense to hypointense (dark). Early Subacute Hemorrhage (2-3 days): Becomes hyperintense (bright) due to methemoglobin formation within red blood cells. Late Subacute Hemorrhage (1-2 weeks): Remains hyperintense due to extracellular methemoglobin. Chronic Hemorrhage (weeks to months): Hypointense due to hemosiderin (iron storage complex). T2-Weighted Images: Acute Hemorrhage (within hours): Hypointense (dark). Early Subacute Hemorrhage (2-3 days): May appear hyperintense to isointense. Late Subacute Hemorrhage (1-2 weeks): Hypointense rim due to hemosiderin with a hyperintense center. Chronic Hemorrhage (weeks to months): Hypointense due to hemosiderin.

MCA ?

[@DrSamsImagingLibrary]

It stands for Middle Cerebral Artery
