OL3I:Opportunistic L3 CT slices for Ischemic heart disease risk assessment

OL3I (pronounced olé) is a multimodal dataset of 8,139 axial computed tomography (CT) slices at the third lumbar vertebrae (L3) level of individuals along with tabular medical record data from up to one year prior to the scan. In addition, labels are provided to indicate individuals that were diagnosed with ischemic heart disease 1 or 5-years after the scan.

Additional details for the selection of patients and processing of data can be found in the attached manuscript. Zambrano Chaves, J. M., Chaudhari, A. S., Wentland, A. L., Desai, A.
