"Bone Reporting and Data System (Bone-RADS) is an algorithm developed and proposed by the Practice Guidelines and Technical Standards Committee of the Society of Skeletal Radiology for the diagnostic workup of incidentally encountered solitary bone lesions in adults on MRI and/or CT 1. It has yet (c. 2022) to be validated in clinical testing 8."

"On CT solitary bone lesions can primarily be classified based on their density into bone lesions of lucent, sclerotic or mixed density. Within the bone reporting and data system (Bone-RADS) two different algorithms with respective flowcharts have been developed for the following 1:"
"Both types of lesions are assessed for attributable pain and aggressive imaging features, that make a lesion suspicious for malignancy if present and thus will lead to a Bone-RADS 4 category."
