- Fig 1.
Plots of the number of LSAs between C-CTA and UHR-CTA. UHR-CTA identified more MCA perforators than C-CTA.
- Fig 2.
A 49-year-old man with anterior cerebral artery dissection. A, C-CTA of a coronal partial MIP (20 mm) image. B, UHR-CTA of a coronal partial MIP (20 mm) image. Bilateral LSAs, particularly left LSAs, are not depicted at all on C-CTA; however, they are depicted from the proximal-to-distal side in UHR-CTA (arrows). Peripheral branches of the anterior cerebral artery, MCA, and posterior cerebral artery in UHR-CTA are also observed more clearly compared with C-CTA.
- Fig 3.
A 74-year-old woman with bilateral MCA aneurysms. A, C-CTA of a coronal partial MIP (20 mm) image. B, UHR-CTA of a coronal partial MIP (20 mm) image. UHR-CTA shows bilateral LSAs more clearly (arrows), and it allows accurate assessment of the variation and structure of the LSAs compared with C-CTA.
