Assessment of the cerebellar arteries with multidetector computed tomography angiography benefits from submillimeter slice thickness

Effect of Right-Sided Versus Left-Sided Contrast Injection on Intra-arterial Opacification Characteristics of Head and Neck Computed Tomography Angiograms and Interactions With Patient Sex, Weight, and Cardiac Output

“…Current standard of practice preferentially administers RSI injections due to the empiric understanding that this results in improved vessel opacification due to shorter venous course to the heart, less venous reflux, and perivenous artifact. Although there are many studies elucidating the effects of CT scanning parameters, contrast injection protocols, and reconstruction techniques on CTAs, 10,14,[21][22][23][24][25][26][27] few have directly investigated right-sided versus left-sided upper extremity contrast injection effects on vessel opacification. Furthermore, it is not known if there are patients who might benefit more from RSI.…”

Endovascular treatment for large and giant fusiform aneurysms of the vertebrobasilar arteries

“…Monitoring of brain stem auditory evoked potentials (BAEPs) was used to detect potential risk of ischemia in balloon occlusion test (BOT) when proximal occlusion of VA was considered. Follow-up evaluation was based on physical examination and imaging studies, including conventional angiography, computed tomographic (CT) angiography or magnetic resonance (MR) angiography as described before [8][9][10].…”

New hybrid reformations of peripheral CT angiography: do we still need axial images?

“…Since the introduction of multidetector row CT (MDCT) scanners [3][4][5] and optimized contrast injection protocols [6,7], the accuracy [8,9] and the clinical utility [10,11] of CT angiography (CTA) for this task have been confirmed by several studies. New MD-CT-scanners deliver an increasing number of axial images, which is of particular advantage for the depiction of intracranial vessels [12]. However, the evaluation of this increasing number of images is a time-consuming challenge for routine clinical practice; thus, 3D reformations are required in addition to facilitate the visualization of complex anatomical structures and to reduce the risk of missed pathologies [13][14][15].…”
