READ-PE pulmonary emboli

CT pulmonary angiography of one patient with acute pulmonary embolism, on a GE or Toshiba scanner, with the emboli drawn by a radiology resident and revised by a radiologist (READ-PE).

  • Cases. A CT pulmonary angiography a patient with acute pulmonary embolism, from its DICOM slices: 0.59 to 0.82 mm pixels, slices 0.625 mm (GE Revolution) or 0.8 mm (Toshiba Aquilion) apart, in whole Hounsfield units, padding and metal values as delivered. No mask.
  • Labels. The emboli, one label, drawn on the CT's own voxels; the masks' NIfTI headers round the slice spacing (0.801 mm for the DICOM's 0.800), so prepare.py gives them the image's geometry, voxel for voxel.
  • Truth. A third-year radiology resident drew the emboli in ITK-SNAP and a board-certified radiologist revised them (de Andrade et al. 2023). One delineation an exam; no agreement between readers is published. The emboli measure 0.07 to 30 mL on the test exams: on the smallest a few voxels' error weighs on the Dice.
  • Start. A mask of the whole image scores a Dice of 0.0005 at the median of the test exams, an Otsu mask 0.0008. TotalSegmentator has no embolus class.
  • Overlap. FUMPE's CT angiographies come from Mashhad, Iran (NeuViz 16); these from Curitiba, Brazil (Hospital de Clínicas UFPR and DAPI, 2018–2019): other hospitals, other patients. No other dataset of the corpus names READ-PE.

About the data

Test cases
10 test exams drawn with seed 2026, five on each scanner, and 10 development exams, from the deposit's 40 (20 GE Revolution, 20 Toshiba Aquilion), one exam a patient. No split is released.
Truth
contours by experts the deposit's embolus masks, drawn in ITK-SNAP by a third-year radiology resident and revised by a board-certified radiologist (de Andrade et al. 2023)
