Imaging in ischemia of bone – A pictorial essay

Abstract

Ischemia of bone is not uncommon and is not recognized clinically unless it is acute. Ischemia of bone marrow in shafts of long bones goes by the name of infarction and is well recognized. Ischemia of epiphysis, small bones and subarticular ends of bones goes by the name of avascular necrosis and ischemia of cortical bone goes by the name of Osteosclerosis. The imaging features of these three entities are described with differential diagnosis wherever necessary.
