• Contrast X-Rays.
– Melibatkan penyuntikan sebuah substansi ke salah satu
kompartemen tubuh yang akan menyerap sinar-X dibanding
jaringan sekitarnya.
– Contohnya adalah: cerebral angiography.
– Vertebral Angiogram shows aneurysm of the top of the Basilar
Artery

X-Ray Computed Tomography
• Computed tomography (CT)  prosedur sinar-X dibantu
komputer yang dapat digunakan untuk
memvisualisasikan otak dan struktur-struktur internal
tubuh (manusia) lainnya.
