[18F]ML-10 Imaging for Assessment of Apoptosis Response of Intracranial Tumor Early after Radiosurgery by PET/CT

Figure 5

Voxel-based subtraction scatterplots showing the effect of CK treatment in a subject with positive apoptotic response (a) and a subject without significantly apoptotic response (b). The X-axes represent the pre-CK radioactivity while the Y-axes represent post-CK radioactivity. Voxels with increased signal are shown in red, representing increased apoptotic activities. Voxels with decreased signal are shown in blue, and voxels with unchanged (change less than ±12.5%) signal are shown in green.
