Bone marrow for assessing the marrow cavity of bones, although with low sensitivity and specificity. For example, normal fatty "yellow" marrow in adult long bones is of low density (-30 to -100 Hounsfield units), between subcutaneous fat and soft tissue. Tissue with increased cellular composition, such as normal "red" marrow or cancer cells within the medullary cavity will measure variably higher in density. MRI is more sensitive and specific for assessing bone bone composition. MRI enables assessment of the average molecular composition of soft tissues, and thus provides information regarding the relative fat content of marrow. In adult humans, "yellow" fatty marrow
Generative tissue and has a unique cellular and biochemical make-up that make it distinct from other tissues of the body. gTissue was discovered through research in the fields of Tissue Engineering and Regenerative Medicine and first created as a dense connective tissue between the brain and skull during the repair of canine dura mater. It has since been successfully created in humans for a wide range of clinical applications in soft tissue healing and repair. Essentially, the gTissue is created by implanting certain types of non-inflammatory ECM biomaterials that are adopted by the host, including repopulation with host cells and blood vessels,
