Osteonecrosis of the jaw fatty degeneration and/or necrosis, often with pooled fat from destroyed adipose cells (oil cysts) and with marrow fibrosis (reticular fatty degeneration)"" are seen. These changes are present even if ""most bony trabeculae appear at first glance viable, mature and otherwise normal, but closer inspection demonstrates focal loss of osteocytes and variable micro cracking (splitting along natural cleavage planes). The microscopic features are similar to those of ischaemic or aseptic osteonecrosis of long bones, corticosteroid-induced osteonecrosis, and the osteomyelitis of caisson (deep-sea diver's) disease"". In the cancellous portion of femoral head it is not uncommon to find trabeculae with apparently intact
Soft tissue growth at cellular level. Growth and remodeling have a major role in the cause of some common soft tissue diseases, like arterial stenosis and aneurisms and any soft tissue fibrosis. Other instance of tissue remodeling is the thickening of the cardiac muscle in response to the growth of blood pressure detected by the arterial wall. There are certain issues that have to be kept in mind when choosing an imaging technique for visualizing soft tissue ECM components. The accuracy of the image analysis relies on the properties and the quality of the raw data and, therefore, the choice of the
