1 Normal >1.2 × 10−3 mm2/s Normal
2 Faint decreased signal 1.0-1.2 × 10−3 mm2/s Mildly abnormal enhancement
3 Moderately dark nodule 0.8-1.0 × 10−3 mm2/s Moderately abnormal enhancement
4 Intensely dark nodule 0.6-0.8 × 10−3 mm2/s Highly abnormal enhancement
5 Dark nodule with mass

<0.6 × 10−3 mm2/s Profoundly abnormal enhancement

The higher the score, the greater the level of suspicion. Regions of interest with scores of 1 and 2 are no more likely to contain cancer than normal tissue and are not usually targeted. A score of 5 indicates cancer in most cases. From Sonn GA, Natarajan S, Margolis DJ, et al.
