摘要: In this chapter, we discuss the factors that affect image quality of DW-MRI and practical methods to improve DW-MR images obtained from clinical scanners. We demonstrate how simple phantoms may be used so high-quality can attained consistently. review relative merits fat-suppression schemes these applied different applications. optimization b-values number required for imaging further illustrate range considerations choices. survey data acquisition using breath-holding, physiological gating or free breathing, choice method relate a particular scanning application. Finally, provide recommendations enable reader develop their own diffusion-weighted protocols in body.
