Preoperative MRTA scan showing the right VA adjacent to the CN-V (yellow box) in the REZ area (yellow localized cross) (A). MRTA-3D-MFI model shows that the right VA and PICA are offending vessels (B). The preoperative CTA/V + DTT + 3DFEISTA fusion image shows the same result as compared to MRTA (C). The CTA/V-DTT-3D-MFI model was more detailed than the MRTA-3D-MFI model, particularly in regard to the morphology of SCA and PICA (D)
