Diffusion-Weighted Magnetic Resonance Imaging Findings of Kidneys with Obstructive Uropathy: Differentiation between Benign and Malignant Etiology

Table 1

Comparison of ADC values of obstructed kidneys with normal kidneys.

𝑏 value	Obstructed kidneys with; benign etiology; Mean ± S.D.	Obstructed kidneys with; malignant etiology; Mean ± S.D.	Normal kidneys; Mean ± S.D.
100^∗	3.12±0.61×10^−3∗∗	3.28±0.44×10^−3∗∗	3.55±0.29×10^−3
600^∗	2.38±0.45×10^−3∗∗	2.57±0.68×10^−3	2.67±0.49×10^−3
1000^∗	1.93±0.33×10^−3∗∗	1.83±0.17×10^−3∗∗	2.09±0.19×10^−3

ADC average values calculated from the following 𝑏 values: 100, 600, and 1000 s/mm².
∗Independent t test, 0.05 significance level.
∗∗The differences are statistically significant between the groups.
