Iain's CT and CTA scans

Iain’s non-contrast CT scan excludes a bleed but shows a dense (white) middle cerebral artery (MCA) on the left due to clot within the artery. There are also some early ischaemic changes (loss of grey/white matter discrimination) visible. A blocked proximal MCA is confirmed on the CTA (arrow).

Drag the words

Iain required an immediate *non-contrast* CT brain scan to exclude a cerebral *bleed* due to him taking an *anticoagulant*. Although, the onset is still less than an hour ago he is not *eligible* for treatment with *thrombectomy* because he is taking *apixaban*. *alteplase* is still an option, so they request a *CTA* to establish whether he has a blocked large *artery*.
