Figure 5From: Increased absorbed liver dose in Selective Internal Radiation Therapy (SIRT) correlates with increased sphere-cluster frequency and absorbed dose inhomogeneity Linear relationship between cluster size and cluster cross-section. 277 clusters found within the 16 biopsies. There is a linear increase in cluster cross-section size (mean number of spheres per section) with cluster size (number of spheres per cluster) (R2 = 0.87, p < 0.05, two-sided t test).Back to article page
