Figure 4: How Adipose Tissue and Lipid Crescents Lead to Multiple Scattering. In A, adipose tissue is shown where the lipid is completely transparent but there is a rapid loss of resolution and contrast with depth (green arrow). The histology is shown in B. In C, there is a rapid loss of contrast with depth relative to muscle due to multiple scattering. In D, cholesterol collections in intima are seen which have similar composition to the fat cells and result in multiple scattering..
