Evaluation of changes of intracranial blood flow after carotid artery stenting using digital subtraction angiography flow assessment

Figure 1 Digital subtraction angiography. A: Time-density curve of digital subtraction angiography lateral view. The change in the concentration of the contrast media, visualized as a change in brightness, was calculated; B: The parameters calculable by the “Flow-Insight” application; C: Lateral view of a pre-operative qualitative image of cerebral blood flow in Case 2; D: Pre-operative N-isopropyl-p-[123I] iodoamphetamine-single-photon emission computed tomography image.
