A summary of the parameters obtained from the EMM to describe contrast medium uptake and washout in small ROI from benign lesions (n =6), malignant lesions (DCIS=9, IDC=2 and ILC=1), liver, heart and blood vessels
| A | α (1 min−1) | β (1 min−1) | γ (1 min−1) | q | R2 | |
|---|---|---|---|---|---|---|
| Benign | 4.0±2.1 | 1.00±1.96 | 0.006±0.011 | 0.0a | 0.8±0.7 | .96±.03 |
| Malignant | 5.7±3.0 | 1.77±0.77 | 0.020±0.014 | 0.0a | 0.8±0.5 | .93±.07 |
| Liver | 2.9±0.8 | 5.88±3.04 | 0.027±0.008 | 0.35±0.12 | 4.0±2.6 | .90±.06 |
| Heart | 5.1±2.8 | 13.4±2.01 | 0.026±0.007 | 0.46±0.15 | 4.5±1.7 | .86±.02 |
| Vessels | 4.9±2.4 | 10.1±7.71 | 0.028±0.015 | 0.03±0.11 | 4.5±3.5 | .86±.10 |
Values are reported as mean±S.D. for all slices.

Since the transition from contrast uptake to washout was undersampled for benign and malignant lesions, γ was set to zero for these curves.
