A comparison between acute and non-acute DVT. Acute thrombus (first line) and non-acute thrombus (second line) were hypointense on b = 0 (a, d), b = 800 s/mm2 (b, e) image. The signal intensity was about the same for acute and non-acute thrombus, while ADC values differed greatly (c, f). Mean ADC of this acute thrombus was above the cutoff of 0.32 × 10− 3 mm2/s, while that of non-acute thrombus was below the cutoff
