Simultaneous multi-slice accelerated diffusion-weighted imaging with higher spatial resolution for patients with liver metastases from neuroendocrine tumours

Highlights: • SMS-DWI achieve higher spatial resolution than cDWI within the same acquisition time. • SMS-DWI provide better detectability and delineation of high signal liver lesions. • Motion correction techniques can further improve the image quality of SMS-DWI. • SMS-DWI with motion correction provide better test-retest variability of ADC values. To evaluate the imaging characteristics of simultaneous multi-slice (SMS) accelerated diffusion-weighted imaging (DWI) with decreased section thickness, with and without motion correction, in comparison to conventional DWI (cDWI) for the detection of lesions in patients with neuroendocrine tumour (NET) liver metastases.
