CT - CT intracranial angiogram
Axial C+ arterial phase
Coronal C+ arterial phase
Sagittal C+ arterial phase
There is a filling defect in the top of basilar artery at the level of the midbrain. Similarly, there is filling defect in P1 segment of the left PCA. These correlate with the hyperdense clots seen in the non-contrasted phase.
Normal contrast is opacification in the remainder of the branches of circle of Willis with no evidence of contrast extravasation or large aneurysmal dilatation.
