Table 2. IVIM Parameters and Sum of Squared Residuals for Two Carcinoma Types and Muscle Tissue.
D* (× 10−3 mm2/s) | Fp (%) | D (× 10−3 mm2/s) | b-Value Threshold (s/mm2) | Residuals | |
---|---|---|---|---|---|
Muscle | 5.7 (5.2–25.7) | 10.5 (8.1–12.3) | 1.40 (1.34–1.43) | 500 (40–500) | 0.29 (0.18–0.62) |
Squamous cell carcinoma | 45.1 (25.1–60.4) | 7.5 (7.0–9.0) | 0.89 (0.75–0.94) | 35 (22.5–50) | 0.74 (0.60–0.92) |
Adenocarcinoma | 12.4 (10.5–21.2) | 9.9 (9.0–11.4) | 0.90 (0.82–0.97) | 150 (100–150) | 0.94 (0.67–1.01) |
Data are median (interquartile range). IVIM = intravoxel incoherent motion
