The relationships between ADC values and Ki-67 LI (A) and ADC values and AgNOR count (B).
Figure 3.
ADC values were measured in tumors with different Ki-67 LI values.
In a low Ki-67 LI (Ki-67 value = 50% and AgNOR count = 2), which was limited to the bowel wall, without mesorectal lymph nodes, the ACD value (1.27 × 10−3 mm2/s, ROIs = 434 mm2) was higher than in a high Ki-67 LI (A: b = 800 s/mm2c image, B: ADC map, C: Ki-67 Immunohistochemical staining). In the high Ki-67 LI range (Ki-67 LI = 90% and AgNOR count = 4), in a tumor staged as T3N2, the ADC value (1.00 × 10−3 mm2/s, ROIs = 438.3 mm2) was lower (D: b = 800 s/mm2c image, E: ADC map, F: Ki-67 Immunohistochemical staining).
