“…Survey of studies focused on 1 vasculopathy revealed intracranial atherosclerotic disease (ICAD) to be the most commonly studied vasculopathy (49%, n = 62, references in the On-line Appendix), followed by arterial dissection (13%, n = 16), 10,12 -26 aneurysm (8%, n = 10), [27][28][29][30][31][32][33][34][35][36] vasculitis (5%, n = 6), [37][38][39][40][41][42] Moyamoya disease (3%, n = 4), [43][44][45][46] postendovascular changes (2%, n = 3), [47][48][49] and reversible cerebral vasoconstriction syndrome (1%, n = 1) 50 ( Fig 3C). Among the 16 publications investigating arterial dissections, 11 used VWI 12,[14][15][16][17][18][22][23][24][25][26] and the other 5 publications 10,13,[19][20][21] assessed intramural hematoma signal characteristics on conventional MR imaging.…”
