title: Problems in aseptic bone necroses diagnostic imaging.
abstract: Aseptic bone necroses are a diverse group of diseases, where the bone necrosis is caused without participation of infectious factor. We can divide osteochondroses and aseptic bone necroses brought about by physical factors, some drugs and systemic disorders. Some locations are more frequent than others, although necrosis can be situated in the every bone. The knowledge of typical location, typical age, risk factors and clinical data usually allows to evaluate changes on the plain film and to make a diagnosis. MRI allows detecting the disease in the very early stage; also it is the conclusive examination, when the pathology on the plain film is invisible. On the basis of the MRI some new aseptic bone necroses classification systems were done, which allow planning the therapy. The radiologist - clinicist cooperation is always necessary to make the proper diagnosis. <br /> The proper use of diagnostic imaging allows making quick and proper diagnosis.
