CT Texture Analysis for Preoperative Identification of Lymphoma from Other Types of Primary Small Bowel Malignancies

Figure 2

Flowchart of texture analysis. Main steps are tumor segmentation, feature extraction and selection, model construction, and validation. GLRLM: gray level run-length matrix; GLCM: gray level cooccurrence matrix; GLSZM: grey level size zone matrix; mRMR: minimum redundancy maximum relevance; LGOCV: leave group out crossvalidation.
