The purpose of this study is to assess whether
noncontrast-enhanced SSFP MRI with a spatially selective
IR pulse can improve the visibility of renal
corticomedullary differentiation to measure renal
cortical thickness in patients showing renal
dysfunction, and to investigate the correlation between
renal cortical thickness and eGFR. Mean corticomedullary
contrast ratio was higher in SSFP images with optimal TI
than in IP images. Additionally, positive correlation
was observed between minimal renal cortical thickness
and eGFR. This fact suggested that non-contrast-enhanced
SSFP MRI using this technique has a potential to
evaluate the renal dysfunction with higher sensitivity
than conventional imaging.
