Healthy volunteer study. (A) The contrast-to-noise ratio (CNR) between the residual blood region and dark lumen decreases with the DANTE pulse train length. The CNR between the white matter and dark lumen has the similar trend. A pulse train length of 150 can adequately suppress venous blood signals while avoiding further signal loss in static tissues. (B) and (C) Representative images from two healthy subjects demonstrate that conventional SPACE imaging may have considerable flow artifacts that mimic thrombus denoted by yellow arrows in B.1 and C.1, whereas DANTE with 150 pulses can help dramatically reduce the artifacts (B.2 and C.2) and allow the visualization of normal sinus structures such as arachnoid granulations denoted by green arrows in B.2.
