The voxel ADC vs. SUV comparisons for all SCCA tumors (a) and all AdenoCA tumors (b). Each point represents a single voxel, and all voxels from all tumors are displayed together. For the SCCAs (a), in the majority of tumors, there is a steeper SUV vs. ADC slope (blue); for two tumors, the slope is not as steep, but there is still a correlation (red). For the AdenoCAs (b), one tumor has a steep SUV vs. ADC slope (blue), but voxels from the rest of the tumors are more erratically scattered (red). When the correlation between ADC and SUV, as measured by Pearson’s r, is compared between SCCAs and AdenoCAs, there is a consistent inverse correlation between these values in SCCAs, but not AdenoCAs (c). Poorly differentiated tumors have a significantly greater inverse correlation between voxel SUV and ADC compared to well/moderately differentiated tumors (d). The correlation between voxel SUV and ADC varies with MTV, though this relationship is primarily driven by the AdenoCAs (e)
