TCIA/TGCA-LIHC portal venous phase CT-scans for cirrhosis classification
<p>These are the scans provided by The Cancer Genome Atlas Liver Hepatocellular Carcinoma (TCGA-LIHC) data collection, published by The Cancer Imaging Archive <a href="https://wiki.cancerimagingarchive.net/pages/viewpage.action?pageId=6885436">here</a> and used in our <a href="https://arxiv.org/abs/2307.04617">MICCAI 2023 paper</a>. You can find the GitHub of the paper <a href="https://arxiv.org/abs/2307.04617">here</a>.</p> <p>All the data are submitted to <a href="https://wiki.cancerimagingarchive.net/display/Public/Data+Usage+Policies+and+Restrictions">TCIA data usage policy</a> and must be strictly respected by future users.</p> <p>The selected scans are in portal venous phase, which is the phase that is clinically used to identify cirrhosis. In this list, you will find all the patients available in the TCGA-LIHC database, regardless of the availability of the annotations or the duplicated patients at different dates. In the dataframe provided in the Git repo, you will find the dataframe with one scan per patient (only at the first date), and with the Ishak score for each patient provided in the TCIA/TGCA database, which are the exact ones that we used in the paper. The names of the scans in the dataframe match exactly the ones below, to ease reproducibility. </p> <p>The scans are already pre-processed and are the exact ones that we use in evaluation phase in the published paper.</p>

DICOM images of abdomen CT phantom in axial, helicoid, iterative and dual energy scans.
<p>The two ZIP files contain the images of a CT phantom of abdomen. DualEnergy.zip contains files of acquisition at 80 kVp and 140 kVp. The second file HelicalAxialIterative.zip contains acquisition done in axial, helicoidal (aka spiral) and iterative reconstruction (Saphire) modes. Axial images have AbdSeq in the name, Helicoidal have Abdomen and B in the filter name, Iterative have Abdomen and I in the filter name. You can compare Exposure in mAs for each acquisition modality, how it diminishes from sequential/helicoidal/axial through helicoidal/spiral to iterative. This scanner if programmed with iterative acquisition can still reduce exposure from helicoidal scan. The acquisition was done on Siemens-Healthineers Somatom Confidence CT scanner. </p> <p>Antonio Ortiz Lora antonio.ortiz.lora.sspa@juntadeandalucia.es</p> <p>Marcin Balcerzyk mbalcerzyk@us.es</p> <div class="ms-editor-squiggler"> </div>
