SMS-acceleration allows for considerable scan time reduction in hepatic DWI without substantial drawbacks in image quality both using respiratory-triggering and free-breathing acquisitions. In the present study set-up, ADC measured in SMS-DWI were lower than in standard DWI which should be considered when using absolute ADC for clinical reading. The demonstrated high image quality of SMS-DWI obtained in FB indicates great potential for scan time reduction in DWI for abdominal and whole-body applications.
