Results of Spearman rank correlation test between rCBV and ADC ratios versus cell and microvessel density
| Density | All Samples (n = 18, N = 81) | Peritumoral Tissue (n = 4, N = 9) | Infiltrated Tissue (n = 17, N = 39) | Bulk Tumor (n = 13, N = 33) |
|---|---|---|---|---|
| r (P) | r (P) | r (P) | r(P) | |
| ADC-cell | 0.11 (.34) | 0.02 (.97) | −0.02 (.90) | −0.20 (.26) |
| ADC-microvessel | −0.20 (.08) | −0.62 (.08) | −0.06 (.72) | −0.36 (.04)* |
| rCBV-cell | 0.37 (.0006)* | −0.07 (.86) | 0.09 (.59) | 0.57 (.0005)* |
| rCBV-microvessel | 0.26 (.02)* | 0.03 (.93) | −0.18 (.28) | 0.46 (.008)* |
Note:—nindicates number of patients; N, number of biopsy samples.
