DICOM series classification and visualization of parameters

Key Investigators

Presenter location: In-person

Project Description

To use and develop AI methods, significant data curation is required. In some cases like prostate cancer segmentation, clinicians often use multiple MRI sequences for diagnosis such as T2, diffusion-weighted series, and derived maps.

Unfortunately, the information describing the sequences is often missing or incorrect, as it’s prone to errors from technicians. The proper sequence could be analyzed visually, but this is cumbersome if thousands of scans need to be analyzed. Therefore, automatic methods for determining the right series are of interest.

We propose methods to aid in the curation of DICOM data, as well as aids to help in vizualization of DICOM parameters.


We would like to develop approaches for aiding in the curation of data. The first will be the development of visualization tools to understand DICOM parameters used in scanning. Secondly, we will develop AI methods for classifying MRI scans, with a focus on prostate cancer.

Approach and Plan

  1. Use packages such as hiplot to visualize DICOM scanning parameters across different collections and modalities in IDC.
  2. Develop approaches for data curation using AI - e.g. determine the scan sequence, or if endorectal coil is present, etc.

Progress and Next Steps

  1. Started repo here for initial hiplot exploration of DICOM tags of T2 weighted axial series of prostate imaging collections from IDC
  2. Had some very helpful discussions with David, Maria and Chris about understanding of parameters and previous work done in this area
  3. Created similar interactive plots for DWI and ADC across different prostate collections
  4. Developed a hierarchical approach for classification of prostate scans, starting with ProstateX collection – for T2 axial, DWI, ADC, and DCE classification.
  5. We’ll later try this out on other prostate collections.
