LUNA22-ISMI

This is a dataset of 1176 lung nodules extracted from the LIDC-IDRI dataset for the educational LUNA22-ISMI challenge. This dataset only contains 3D patches of nodules (size 128 x 128 x 64 in x, y, and z directions) that had been annotated by at least 3 out of 4 radiologists (following LUNA16 criteria, which produces 1186 nodules). The nodules are always located at the center of the 3D patch. Radiologist scores for nodule type and malignancy are provided along with this dataset. 10 nodules have been excluded as part of a hidden test set for phase 1 of the LUNA22-ISMI challenge.
