WebThe flow voids is the condition occurs when the MRI image has lost its signal due to flow of bloods and other fluids such as cerebrospinal fluid (CSF) and urine. Generally, the MRI images particularly the vessels that contain vigorously flowing blood is seen low signal and this may reflect to vascular patency. Moreover, the manual delineation method to visually … WebForum ( 2) Flow Void. The occurrence of a low signal in regions of flow. For a spin echo sequence, this is caused in part by a lack of refocusing of blood, which is excited by the 90° pulse but not by the 180° pulse. For a gradient echo sequence, this is caused by the dephasing of blood signal.
