Figure 1From: Heterogeneity of microsphere distribution in resected liver and tumour tissue following selective intrahepatic radiotherapyLight microscopy images illustrating the three main types of microsphere aggregations found in Pt 2. (A) Single isolated sphere in an arteriole in a small portal tract, magnified × 200. (B) A large cluster of 27 spheres in a relatively large portal tract with a wide arteriole, ×100. Based on adjacent slices, this cluster was part of a cluster of 36 spheres.Back to article page
