We provide the first publicly available annotated imaging dataset of cancerous CT spines to help develop artificial intelligence frameworks for automatic vertebrae segmentation and classification. This collection contains a dataset of 55 CT scans collected on patients with various types of primary cancers at two different institutions. In addition to raw images, data include manual segmentations and contours, vertebral level labeling, vertebral lesion-type classifications, and patient demographic details. Our automated segmentation model uses nnU-Net, a freely available open-source framework for deep learning in healthcare imaging, and is made publicly available. This data will facilitate the development and validation of models for predicting the mechanical response to loading and the resulting risk of fractures and spinal deformity.  \nBackground & Summary  \nIn 2022, it is estimated that there were more than 1.9 million new cancer cases in the United States (1) . After the liver and the lungs, bones are the third most frequent target site of metastases (1), with the spine being the most frequent site of bone metastases (2, 3) . Cancer patient autopsies (4) showed 73% of breast, 68% of prostate, and 35% of renal and lung subjects had vertebral bone metastases. Up to 50% of spinal metastases receive some form of treatment, and 5-10% receive surgical management (5, 6, 7) . Patients are at high risk for skeletal adverse events, including bone pain, fracture, hypercalcemia, and neurological dysfunction secondary to the spinal cord or cauda equina compression (4, 9, 10, 11, 12), that may require palliative radiotherapy, surgery, or both. Skeletal adverse events profoundly and negatively impact patients' lives (13), causing disability and often requiring high doses of narcotics, causing reduced quality of life (14) . They also increase psychological distress, decrease social functioning (15), and significantly impair normal function (16) .  \nAlthough the impact of spinal metastasis on the vertebral column anatomical integrity is readily imaged with MRI and CT (17, 18, 19, 20, 21, 22, 23), in the absence of quantitative assessment (11, 24, 25, 26), standard-of-care imaging modalities (19, 27, 28, 29) do not provide precise estimates of the structural competence of the spine (17, 18, 19, 20, 21, 22, 23) . This limited ability has a profound, negative impact on these patients' clinical care. Clinicians are forced to decide without objective quantitative criteria whether surgery or vertebral augmentation should be offered or withheld in attempts to treat to reduce the risk of fracture or to control pain. This can be particularly tragic when treatment could have been offered prior to the devel","cbCaidNhaiQz4FFZ","https://ap.wps.com/l/cbCaidNhaiQz4FFZ","pdf",3554388,"English","# Abstract\n# Background & Summary\n## Motivation and clinical impact\n## Imaging limitations and need for quantitative assessment\n## Related deep learning progress and dataset gaps\n## Contributions of the new dataset","[{\"question\":\"What dataset is being provided for metastatic spine disease research?\",\"answer\":\"A publicly available annotated imaging dataset of cancerous CT spines, including raw CT images and detailed annotations for vertebrae and vertebral lesions.\"},{\"question\":\"What annotations and labels are included in the dataset?\",\"answer\":\"The collection includes manual segmentations and contours, vertebral level labeling, vertebral lesion-type classifications, and patient demographic details.\"},{\"question\":\"What baseline machine learning model is included with the release?\",\"answer\":\"An automated segmentation model based on nnU-Net, an open-source deep learning framework for healthcare imaging, is made publicly available.\"}]","An Open Annotated Dataset and Baseline Machine Learning Model for Segmentation of Vertebrae with Metastatic Bone Lesions from CT | PDF",1789999072]
