Incorporating MSDE
into breath-holding 3D GRASE-MRCP made it possible to suppress the background
signals without extending the image time and reducing the image quality.
Full MIP image of GRASE-MRCP and MSDE-GRASE-MRCP
On the GRASE-MRCP image, signals from veins and portal veins in the liver
remained, but they were well suppressed on the MSDE-GRASE-MRCP image. There was
no significant difference in image quality.
Raw image of GRASE-MRCP and MSDE-GRASE-MRCP
On the GRASE-MRCP image, the intrahepatic portal vein along with a biliary
duct had high signal but was well suppressed on the MSDE-GRASE-MRCP image.
