Fig. 2From: 3.0T MRI for long-term observation of lung nodules post cryoablation: a pilot studyPost-contrast images of venous phase (a), T1WI (b), and T2WI (c) of a non-progressive lesion. At the early stage (1 day, 1-month and 3-month), there was no definite enhancement in the ablation zone; later, mild enhancement was noted. Similarly, at the early stage the time-signal curve was a straight line type, and later became an inflow typeBack to article page
