Results
MPR and partial MIP images of 3D-fusion angiography clearly demonstrated feeding arteries,
shunted pouches,
and draining vein in all but one patient.
Regarding the visualization of feeding arteries,
small feeding arteries running very closely to the bony structure or trasosseously could be depicted on 3D fusion angiography more clearly than 3D digital angiography in 10 lesions (Fig.
2-8) (Fig.
9-16) (Fig 24-27).
In 5 lesions,
feeding arteries were well depicted on both 3D fusion angiography and 3D digital angiography. In the remaining 1 lesion in a patient who showed disturbance of consciousness caused by TSSDAVFs at angiographic examination,
some of the small feeding arteries could not be well evaluated on 3D fusion images due to motion artifact.
Shunted pouches were well depicted on both 3D fusion images and 3D digital angiography images in 14 lesions (Fig.
17-23),
and more clearly visualized on 3D fusion images in 2 lesions which were located at the superior petrosal sinus and the TSS.
For the draining vein,
a tiny draining vein of the inferior temporal vein from the TSS DAVFs could be demonstrated on 3D fusion images but not on 3D digital angiography.
In the other 15 lesions,
draining veins were well demonstrated on both 3D fusion images and 3D digital angiography images.
