WebMRI Parameters. All brain MR imaging was acquired using a 3-Tesla MR scanner (Discovery MR 750W system;GE Healthcare, Milwaukee, WI, USA) with an eight-channel phased-array head coil. During the whole MRI scanning, subjects were required to keep their eyes closed while awake and keep their mind blank. WebSep 29, 2024 · An intriguing development is the use of the heartbeat itself as intrinsic driver for magnetic resonance elastography. 18,19 First, the hammering of cardiac pulsations on the arterioles and capillaries has been proposed as an important mechanism for vessel wall changes, as well as a key parameter in drainage of waste products. 52 Therefore, by …
