Table 3.
Differences in rSI T1, rSI T2, ER and ADCm between “invasive and proliferative” vs other PM groups. Significant differences (*) were detected in ADCm and ER values.
| Clinicopathologicalclassification | Othergroups(Grade 1a,1b,2a) | Invasive and Proliferative(2b) | p-value |
|---|---|---|---|
| rSI T1 | 1.07 (1.07–1.09) | 1.06 (1.02–1.10) | 0.600 |
| rSI T2 | 2.15 (1.93–2.18) | 1.89 (1.75–2.26) | 0.602 |
| ER | 2.14 (1.98–2.29) | 1.92 (1.85–1.92) | *0.028 |
| ADCm | 0.869 (0.793–1.051) | 556.14 (504.92–599.91) | 0.117 |
| rADCm | 1.05 (1.00–1.08) | 0.67 (0.64–0.81) | 0.117 |
ADCm, mean apparent diffusion coefficient (x 10-6 mm2/sec); ER, enhancement ratio; Ki-67 LI, Ki-67 labelling index; rADCm, relative mean ADC; rSI T1, signal intensity ratio T1-weighted images; rSI T2, signal intensity ratio T2-weighted images.
