Table 1.

The mean ADC and R2* values of kidneys in patients with LN compared with healthy volunteers $\left(\overline{\mathit{x}}\mathbf{\pm }\mathit{s}\right)$

	ADC (×10 −3  mm 2 / s)	R2* of cortex (1/sec)	R2*of medulla (1/sec)
Normal kidneys	2.52 ± 0.17	12.63 ± 1.40	18.14 ± 2.51
Kidneys with LN	2.40 ± 0.25	11.03 ± 1.60	14.05 ± 3.38
P value	0.048	0.045	0.008

ADC: apparent diffusion coefficient; LN: lupus nephritis.
