The Headlines of this lecture include: – Purpose of this 3d Angio study – Materials – Technique of i.a. cerebral DSA – Technique of 3D CTA – TYpe, age and number of Aneurysms – Size of aneurysm-max D (mm) – Visualisation of neck – Demonstration of vessels at the neck of aneurysm – Demonstration of vessels around the fundus – Mass effect due to extraluminal thrombus – Advantages and Limitations of 3D CTA – Advantages and disadvantages of i.a. DSA Conclusion: 3D recon capability of CTA is an excellent minimally invasive imaging modality in the evaluation of intra-cranial aneurysms 3D CTA is complimentary to i.a. DSA. Replacement of i.a.
