PRIMARY OBJECTIVES:
I. Enhancing tumors with high diffusion measurements (low apparent diffusion coefficient \[ADCL\] \> 1.24 um\^2/ms) will have higher DCN protein expression compared with tumors exhibiting low diffusion measurements (ADCL \< 1.24 um\^2/ms.) (Aim 1A) II. Enhancing tumors with high diffusion measurements (low apparent diffusion coefficient \[ADCL\] \> 1.24 um\^2/ms) will have higher deoxyribonucleic acid (DNA) expression compared with tumors exhibiting low diffusion measurements (ADCL \< 1.24 um\^2/ms.) (Aim 1B) III. Enhancing tumors with high diffusion measurements (low apparent diffusion coefficient \[ADCL\] \> 1.24 um\^2/ms) will have higher ribonucleic acid (RNA) expression compared with tumors exhibiting low diffusion measurements (ADCL \< 1.24 um\^2/ms.) (Aim 1C) IV. Mesenchymal-Like (MES-like) cells will have higher frequency of incidence of tumors with high diffusion measurements (ADCL \> 1.24 um\^2/ms) and higher overall DCN expression levels compared to other genotypes.
SECONDARY OBJECTIVE:
I. DCN immunohistochemistry (IHC), in-situ hybridization (ISH), and RNA expression within the tumor will be linearly correlated with continuous values of diffusion measurements (ADCL).
OUTLINE:
Patients undergo one MRI scan over approximately 1 hour prior to surgery.
