3D cerebral angiography: radiation dose comparison with digital subtraction angiography.
BACKGROUND AND PURPOSE As the use of 3D rotational angiography (3D RA) for the evaluation of cerebral vasculature becomes more widespread, it is important to evaluate this imaging method's effect on patient radiation dose. The purpose of the study is to measure 3D RA radiation dose as compared with biplanar digital subtraction angiography (DSA). METHODS The distribution and peak skin dose wer...
متن کاملInternal carotid artery stenosis measurement: comparison of 3D computed rotational angiography and conventional digital subtraction angiography.
BACKGROUND AND PURPOSE Clinical trials have shown that carotid endarterectomy reduces stroke risk in symptomatic individuals with severe internal carotid artery (ICA) stenosis. As a result of these trials, digital subtraction angiography (DSA) became a standard of reference for ICA stenosis diagnosis. Newer 3D techniques provide a larger number of views than DSA, which may influence the estimat...
متن کامل3D rotational digital subtraction angiography may underestimate intracranial aneurysms: findings from two basilar aneurysms.
3D digital subtraction angiography (DSA) allows clinicians to review intracranial aneurysms and other vascular lesions. We report 2 basilar aneurysms that were imaged by both 3D DSA and DynaCT. These 2 techniques produced very different aneurysm appearances. Anterior portions of the aneurysms were invisible on 3D DSA but were revealed by DynaCT. These aneurysms appeared to have been flattened b...
متن کاملExtravasation from rupturing aneurysm demonstrated by 3D digital subtraction angiography.
We describe the 3D digital subtraction angiography (3D-DSA) image of extravasation from a rupturing aneurysm. This image clearly showed that the extravasation was coming from a pseudoaneurysm on an aneurysmal wall. To the best of our knowledge, this is the first demonstration of a 3D-DSA image of a rupturing aneurysm.
متن کاملComparison of 2D and 3D digital subtraction angiography in evaluation of intracranial aneurysms.
BACKGROUND AND PURPOSE Although digital subtraction angiography (DSA) is considered the criterion standard for depiction of intracranial aneurysms, it is often difficult to determine the relationship of overlapping vessels to aneurysms when using 2D DSA. We compared 2D and 3D DSA in evaluation of intracranial aneurysms. METHODS Thirty-six consecutive patients with cerebral aneurysms underwent...
