Jan 28 2019 In subtraction CT angiography sCTA a non contrast CT acquisition is subtracted from a contrast enhanced CTA acquisition sCTA has shown to produce comparable results to digital subtraction angiography DSA in the detection and classification of intracranial aneurysms 1 2 3 sCTA is advantageous over DSA because of its non invasive
Digital subtraction angiography History Angiography is largely possible thanks to the Seldinger technique first described in 1953 for intravascular access Digital subtraction angiography whereby a pre contrast image is acquired then subtracted from subsequent post contrast images was made possible in the 1970s thanks to real time refreshing of the
Intravenous digital subtraction angiography was used to determine prospectively the positional variations of the common carotid bifurcation in 100 consecutive patients with clinically suspected arteriosclerotic disease The most common position 97/200 48 5 of the external carotid artery was anteromedial to the internal carotid artery

We sought to evaluate the accuracy of quantitative three dimensional 3D CT angiography CTA for the assessment of coronary luminal stenosis using digital subtraction angiography DSA as the standard of reference Twenty three patients with 54 lesions were referred for CTA followed by DSA The CTA scans were performed with 256 slice spiral CT 3D CTA were
X ray contrast arteriography has traditionally been used for pre operative evaluation in living kidney donors However magnetic resonance angiography MRA offers a non invasive alternative which has been considered to be less accurate This study was performed to determine whether MRA in the pre operative investigation of living kidney donors provides
DIGITAL SUBTRACTION ANGIOGRAPHY DSA is a relatively new technique which integrates digital data collection and computer processing to produce a medical image X ray signals are detected electroni cally rather than on film and then converted to digital form to be processed by a computer before being displayed The rapid development of new
Oct 31 2020 This paper aimed to study the agreement and repeatability both intra and interobserver of infrapopliteal lesion assessment with magnetic resonance angiography MRA using the TransAtlantic Inter Society Consensus TASC II criteria with perioperative digital subtraction angiography DSA as a reference Sixty eight patients with an MRA preceding
Objective Endovascular aneurysm repair EVAR can result in high radiation dose to patients and operators This prospective randomized study aimed to assess whether patient radiation dose sustained during EVAR could be decreased by predominantly using digital fluoroscopy DF vs the standard technique using digital subtraction angiography DSA
