Digital subtraction angiography of the intracranial vascular system: comparative study in 55 patients.
Intracranial vessels were examined in 55 patients with both conventional selective catheterization and intravenous digital subtraction angiography using a prototype digital subtraction unit. In 65% of the patients, the digital subtraction angiogram was diagnostic, but the overall quality was inferior to conventional selective angiography. In 22%, the digital subtraction angiogram provided diagn...
متن کاملA comparison between magnetic resonance angiography at 3 teslas (time-of-flight and contrast-enhanced) and flat-panel digital subtraction angiography in the assessment of embolized brain aneurysms
PURPOSE To compare the time-of-flight and contrast-enhanced- magnetic resonance angiography techniques in a 3 Tesla magnetic resonance unit with digital subtraction angiography with the latest flat-panel technology and 3D reconstruction in the evaluation of embolized cerebral aneurysms. INTRODUCTION Many embolized aneurysms are subject to a recurrence of intra-aneurismal filling. Traditionall...
متن کاملLarge-cohort comparison between three-dimensional time-of-flight magnetic resonance and rotational digital subtraction angiographies in intracranial aneurysm detection.
BACKGROUND AND PURPOSE The value of MR angiography varies in diagnosis of intracranial aneurysms due to the difference of equipment and imaging technique. This study was to compare the effectiveness of 3-dimensional time-of-flight MR angiography at 3 T and rotational digital subtraction angiography, both with volume rendering (VR), in detecting intracranial aneurysms. METHODS One hundred thir...
متن کاملDigital subtraction cerebral angiography by intraarterial injection: comparison with conventional angiography.
For 4 months, a prototype digital subtraction system was used to obtain images of the cerebral vasculature after intraarterial contrast injections. In 12 instances, the intraarterial injections were recorded with both a digital subtraction unit and conventional direct magnification film-screen system. The digital subtraction and conventional film subtraction images were compared and graded for ...
متن کاملDigital subtraction angiography in patients with cerebral ischaemic attacks and normal continuous wave doppler studies.
The cervico-cranial arteries were studied using digital subtraction angiography in 50 patients with reversible cerebral ischaemic attacks and normal continuous wave Doppler examination. Digital subtraction angiography was able to visualise the arteries satisfactorily in 45 patients (90%), and revealed minor arterial abnormalities in 12 patients (24%). However, neither occlusions nor stenoses gr...
متن کاملDigital subtraction angiography of glomus tympanicum and jugulare tumors.
Radiologic procedures used to evaluate patients with suspected glomus tumor have included plain skull radiography, temporal bone tomography, computed tomography, and cerebral angiography. Of these, only angiography has proven reliable as a screening procedure for small glomus tympanicum and jugulare tumors. Digital subtraction angiography was used as the initial examination for suspected paraga...
