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 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 کاملThe comparative study on diagnostic validity of cerebral aneurysm by computed tomography angiography versus digital subtraction angiography after subarachnoid hemorrhage*
BACKGROUND In order to declare the preoperative diagnostic value of brain aneurysms, two radiological modalities, computed tomographic angiography and digital subtraction angiography were compared. METHODS In this descriptive analytic study, diagnostic value of computed tomographic angiography (CTA) was compared with digital subtraction angiography (DSA). Sensitivity, specificity, positive an...
متن کاملComparison of 2D digital subtraction angiography and 3D rotational angiography in the evaluation of dome-to-neck ratio.
BACKGROUND AND PURPOSE Dome-to-neck ratio of intracranial aneurysms is an important predictor of outcomes of endovascular coiling. 3D imaging techniques are increasingly used in evaluating the dome-to-neck ratio of aneurysms for intervention. The purpose of this study was to determine whether 3D rotational angiography (3DRA) can be used to determine accurately the dome-to-neck ratio of intracra...
