Summary
Contrast-enhanced spectral mammography (CESM) is done using the standard digital mammography equipment, with additional software that performs dual-energy image acquisition. The dataset is a collection of 2006 CESM images all high resolution with an average of 2355 x 1315 pixels. Each image with its corresponding manual annotation (breast composition, mass shape, mass margin, mass density, architectural distortion, asymmetries, calcification type, calcification distribution, mass enhancement pattern, non-mass enhancement pattern, non-mass enhancement distribution, and overall BIRADS assessment) is compiled into 1 Excel file. Moreover, full medical reports are provided for each case (DOCX) along with manual segmentation annotation for the abnormal findings in each image (CSV file).Deep learning (DL) has a promising potential in helping radiologists provide a more accurate diagnosis. However, fully annotated and large-sized datasets are required. In the past couple of years, a few public mammography datasets were released. These datasets contain digital mammography images only, and none include CESM images.
Acquisition protocol:
Two minutes after intravenously injecting the patient with non-ionic low-osmolar iodinated contrast material (dose: 1.5 mL/kg), craniocaudal (CC) and mediolateral oblique (MLO) views are obtained. Each view comprises two exposures, one with low energy (peak kilo-voltage values ranging from 26 to 31kVp) and one with high energy (45 to 49 kVp). A complete examination is carried out in about 5-6 minutes.
Image preprocessing:
The images were converted from DICOM to JPEG using RadiAnt with best 100% image quality (lossless).

This tool was used for the segmentation annotation: https://www.robots.ox.ac.uk/~vgg/software/via/via.html
It can be used to show the annotations on the images by clicking on Annotation--> import annotations (from csv), and then proceeding to upload any image to view the annotations drawn over it.
Moreover, a helper repository is created to help with pre-processing, model training, model evaluation, and segmentation annotation loading: https://github.com/omar-mohamed/CDD-CESM-Dataset
Regarding the tabs on the annotations Excel file, these are commonly used radiological descriptors as defined by the American College of Radiology 2013 lexicon.
