Intravoxel incoherent motion diffusion-weighted imaging for monitoring chemotherapeutic efficacy in gastric cancer

Figure 4 Representative scatter diagrams showing the relationships between intravoxel incoherent motion diffusion-weighted imaging derived parameters and the histological features (n = 25). A and B: ADC and D were positively correlated with tumor necrosis fraction; C and D: f and D^* were positively correlated with microvascular density of tumor; E and F: ADC, D were positively correlated with tumor cellular apoptosis; G and H: f and D^* were negatively correlated with tumor cellular apoptosis. P values are shown in Table 2. ADC: Apparent diffusion coefficient.
