3.2.3.2 Ablation zone lesions A 5-point score should be used to denote suspicion of recurrence within the ablation zone on a per-lesion basis. PI-RADS v2.1 scoring criteria should not be used. Instead, Figure 1 shows the recommended TARGET score design and examples of its use. This two-tier algorithm incorporates a major DCE sequence and joint minor DWI and T2W sequences. Each sequence should be individually assessed on a scale from 1 to 3: 1 = nonsuspicious; 2 = equivocal; and 3 = suspicious.
