Table 6. Comparison of ADC, FF, and numbers of focal lesions between low and high sFLC-ratio groups in patients with different infiltration patterns.
| sFLC-ratio | Normal/diffuse infiltration pattern | Focal infiltration pattern | ||||
|---|---|---|---|---|---|---|
| ADC (×10−3 mm2/s) | FF (%) | ADC (×10−3 mm2/s) | FF (%) | Numbers of focal lesions | ||
| Low ratio group | 0.52±0.24 | 41.2±22.7* | 0.85±0.13 | 13.8±6.6 | 18.1±13.5 | |
| High ratio group | 0.60±0.17 | 27.4±22.4 | 0.87±0.25 | 13.6±5.6 | 16.6±15.5 | |
| t | −1.428 | 2.326 | −0.307 | 0.104 | 0.289 | |
| P | 0.158 | 0.023 | 0.762 | 0.918 | 0.774 | |
*, significant change (P<0.05) compared with high ratio group. sFLC-ratio, involved/uninvolved serum free light-chain ratio; ADC, apparent diffusion coefficient; FF, fat fraction.
