avascular necrosis; Death of bone tissue

**Avascular necrosis** is a type of disease that occurs following a temporary or permanent lack of blood supply to the bone.... When the blood supply to the bone is cut off, the bone tissue dies and causes it to collapse. If avascular necrosis occurs near the joint, the surface of the joint may also collapse...

CT scan shows details of bones, muscles, fat and organs and shows more details than X-rays. ### MRI Due to its technology, this method displays accurate images of body organs and structures. ### radionuclide bone scan This test shows blood flow to the bone and cell activity inside the bone. ### biopsy Tissue samples are removed for examination under a microscope during surgery or with a needle.
