However, limited data exists to support its efficacy. In this study, we assessed the potential benefits of RHI. We hypothesized that RHI use is associated with improved procedural efficiency without loss of angiographic image quality or increase in radiation exposure.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A single-institution single-physician retrospective cohort study of patients who underwent cerebral digital subtraction angiography (DSA) or middle meningeal artery embolization (MMAE) under conscious sedation over a 1-year period was conducted.
