Avascular Necrosis Diagnosis
The diagnosis of aseptic necrosis can often, but not always, be made with X-rays. By the time changes are apparent by plain film X-ray testing, there has been substantial damage to the bone affected. Therefore, bone changes visible on plain film X-ray are considered a later-stage finding. This makes it important that you share all your medical conditions and social habits with your health-care provider so she can make a decision if you are at risk for avascular necrosis even before plain X-rays reveal this disease. Earlier signs of avascular necrosis can be detected with an MRI scan (magnetic resonance imaging) or suggested by a nuclear bone scan.
It is important to note that when avascular necrosis is not caused by trauma, it is possible to have multiple joints involved, such as the hips as well as the shoulders or knees.
