Illustration of the patients (no 3, 6 and 7) with diverse DTI characteristics on the diffusion dependent images b700 a, d, g, ADC b, e, h and tractography c, f, i. In patient no 3 (a–c) generalized changes were seen in the left kidney with increased b700, decreased ADC and patchy changes of the tracks on the tractography. In patient no 6 d–f there was an apico-lateral discrete increased signal with a central small low signal area (arrow) on the b700 of unclear etiologic. Distorted track pattern could be seen on the tractography in this area. In patient no 7 g–i there was a decreased ADC signal in the upper half of the right kidney showing less tracks with some distortion, but no signal increase could be depicted visually on the b700
