Abstract

A method for characterizing regions on a map or image generated from diffusion image data of a region of a patient's body, including: loading into a data processing device image data achieved by calculation from MR diffusion imaging; providing a first threshold level to distinguish pixels with image data values that are above or below the values found that are not representative of pathological portions of the region; providing a second threshold level higher than the first threshold; deriving a measure related to the gradient pattern of those pixels that lie within a margin zone defined by those pixels that satisfy a criterion of the second threshold but do not satisfy a criterion of the first threshold and; outputting the measure related to the gradient as a parameter indicative of the likelihood that the pixels that are within the margin zone and/or a region of the body part are cancerous.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A method for characterizing regions on a map or image generated from diffusion image data of a region of a patient's body, comprising:
 loading into a data processing device image data achieved by calculation from MR diffusion imaging;   providing a first threshold level to distinguish pixels with image data values that are above or below the values found that are not representative of pathological portions of the region of the patient's body;   providing a second threshold level that is higher than the first threshold;   deriving a measure related to the gradient pattern of those pixels that lie within a margin zone defined by those pixels that satisfy a criterion of the second threshold but do not satisfy a criterion of the first threshold and;   outputting the measure related to the gradient as a parameter indicative of the likelihood that the pixels that are within the margin zone and/or a region of the body part are cancerous.   
     
     
         2 . The method of  claim 1 , wherein the second computed value is independent of the presence or lack of presence of a contrast agent. 
     
     
         3 . The method of  claim 1 , wherein the scans are performed while the region of the patient's body is free of contrast agent. 
     
     
         4 . The method of  claim 1 , wherein the region of the patient's body consists of at least a portion of a breast.
