HCFMRP Sacroiliitis (v1)

Dataset composed of magnetic resonance imaging (MRI) of the sacroiliac joints of 48 patients from the Ribeirão Preto Medical School of University of São Paulo (Brazil). The selected patients are represented in 51 studies, 99 series and 594 images in the DICOM protocol, all anonymized. For each DICOM series, 6 consecutive images (slices) of the sacroiliac joints were obtained in the coronal plane, which were evaluated according to the Spondyloarthritis Research Consortium of Canada (SPARCC) MRI diagnostic criteria. Each DICOM image is accompanied by a PSD file containing the original image and a segmentation mask in PNG format. The masks indicate the location of the sacroiliac joints. The dataset contains, therefore, 1782 image files.

The files are organized into two main directories, STIR and SPAIR, representing the two fat-saturated MRI techniques we adopted for this study. Each of them is subdivided into "Positive" and "Negative", indicating whether there are findings compatible with sacroiliitis.
