ARDL<\/dt>\n
ARDL is available on recent upgrades to GE scanners.
ARDL is a denoising technique.<\/dd>\n
Notes<\/dt>\n
Like any protocol update, each radiology department must test any change to protocol and get chief radiologist approval prior to implementing.
Recent upgrades to GE scanners removed the imaging option “No Phase Wrap (NPW)” and now has a “NPW Factor” that can be reduced or increased to prevent wrap.<\/dd>\n<\/dl>\n<\/section>\n
