(*)—Vessel was non-descript with the standard, but visualized with the manually window.
(SAME)—The standard window yielded good image quality after visual assessment.
(ND)—Vessel was non-descript.
(—)—Subject 7 exhibited having a small rudimentary right with left-dominance, thus the RCA-mid to distal end was not present.
BOLD—Lumen-to-Myocardium CNR.
