Systems and methods for diagnosing tumors in a subject by performing a quantitative analysis of texture-based features of a tumor object in a radiological image

A method for diagnosing tumors in a subject by performing a quantitative analysis of a radiological image, comprising:

• identifying, using a processor, a region of interest (ROI) in the radiological image;
• segmenting the ROI from the radiological image using the processor;
• identifying a tumor object in the segmented ROI using the processor;
• segmenting the tumor object from the segmented ROI using the processor;
• extracting, by the processor, a plurality of quantitative features describing the segmented tumor object;
• and
• classifying the tumor object based on the extracted quantitative features using the processor, wherein the quantitative features include one or more shape-based features.
