Summary

At the time of our study, 108 cases with breast MRI data were available in the The Cancer Genome Atlas Breast Invasive Carcinoma Collection (TCGA-BRCA) collection. In order to minimize variations in image quality across the multi-institutional cases we included only breast MRI studies acquired on GE 1.5 Tesla magnet strength scanners (GE Medical Systems, Milwaukee, Wisconsin, USA) scanners, yielding a total of 93 cases. We then excluded cases that had missing images in the dynamic sequence (1 patient), or at the time did not have gene expression analysis available in the TCGA Data Portal (8 patients). After these criteria, a dataset of 84 breast cancer patients resulted, with MRIs from four institutions: Memorial Sloan Kettering Cancer Center, the Mayo Clinic, the University of Pittsburgh Medical Center, and the Roswell Park Cancer Institute. The resulting cases contributed by each institution were 9 (date range 1999-2002), 5 (1999-2003), 46 (1999-2004), and 24 (1999-2002), respectively. The dataset of biopsy proven invasive breast cancers included 74 (88%) ductal, 8 (10%) lobular, and 2 (2%) mixed. Of these, 73 (87%) were ER+, 67 (80%) were PR+, and 19 (23%) were HER2+.  Various types of analyses were conducted using the combined imaging, genomic, and clinical data.  Those analyses are described within several manuscripts created by the group (cited below).  Additional information about the methodology for how the Radiologist Annotations file can be found on the TCGA Breast Image Feature Scoring Project page.

Detailed Description

How to use the Segmentations

With regards to the naming structure, *S2-1.les: S2 means DCE-MRI sequence 2, lesion #1. Sometimes, there are multiple DCE-MRI sequences on TCIA data, and so the team used the sequence that corresponded to the one on which the radiologists annotated the truth.  Each of our tumor segmentation files is a binary file, consisting of the following format:

1. six uint16 values for the inclusive coordinates of the lesion’s cuboid , relative to the image:
y_start y_end
x_start x_end
z_start z_end

2. the N int8 on/off voxels (0 or 1) for the above specified cube, where N = (y_end y_start +1) * (x_end – x_start + 1) * (z_end – z_start + 1).

A voxel value of 1 denotes that it is part of the lesion, while a value of zero denotes it is not.

Please reference these data  extracted using version  V2010  of the UChicago MRI Quantitative Radiomics workstation.

 

The LES file is binary in format and contains the coordinates and shape mask volume of the lesion. It consists of six 2-byte short integer values which represent a 3×2 array of y,x,z start and end points. The remainder of the file contains the 1-byte mask values for the lesion voxels.

The following MATLAB statement reads a LES file:

 

[binles, lesRange] = loadlesion(targetfile);

 

where targetfile is a string of the file name path.

 

and where loadlesion.m is:

 

function [binles,rg]=loadlesion(targetfile)

    fid=fopen(targetfile,’r’);

    if fid ~=-1

        rg=fread(fid,[3 2],’uint16′)

        sz=rg(:,2)-rg(:,1)+1;

        binles=fread(fid,[prod(sz) 1],’int8′);

        binles=reshape(binles,sz’);

        fclose(fid);

        range=[rg(5)-rg(2)+1,rg(4)-rg(1)+1,rg(6)-rg(3)+1]

    else

        binles=[];

        rg=[];

    end

end

 

For example, if

rg =

122   150

327   379

71    84

then

yEnd = 150 and yStart = 122

xEnd = 379 and xStart = 327

zEnd = 84 and zStart = 71
