Imaging Intratumor Heterogeneity: Role in Therapy Response, Resistance, and Clinical Outcome
24 Nov 2014
Abstract excerpt
Tumors exhibit genomic and phenotypic heterogeneity, which has prognostic significance and may influence response to therapy. Imaging can quantify the spatial variation in architecture and function of individual tumors through quantifying basic biophysical parameters such as CT density or MRI signal relaxation rate; through measurements of blood flow, hypoxia, metabolism, cell death, and other phenotypic...
