“…In patients with direct damage to the bone vasculature (such as a femoral neck fracture) or direct lesion of bone components (such as radiation-induced damage), the cause can be clearly identified. However, in many patients, the mechanisms behind this disorder are not fully understood (1)(2)(3) .…”

The term avascular necrosis describes any one of a number of bone diseases that have a common mechanism: the death of bone components due to lack of blood supply. Avascular necrosis can occur in diverse parts of the skeleton, each location-specific form not only receiving a distinct designation but also presenting unique epidemiologic characteristics. However, the imaging findings are similar in all of the forms, which pass through well-described radiological phases, regardless of the site of involvement. Because avascular necrosis can cause considerable morbidity if not properly detected and managed, the radiologist plays a fundamental role. The present study provides a brief review of the main radiological aspects of the various forms of avascular necrosis, illustrated on the basis of a collection of cases from our institution.

“…Blood flow impairment leading to bone cell death seems to be common to most of the proposed etiologies of avascular necrosis. The process is usually progressive, resulting in ischemia and gradual bone destruction within a few months to two years in most patients (1)(2)(3) .…”

“…The evaluation of the musculoskeletal system by magnetic resonance imaging (MRI) has been the subject of a series of recent publications in the radiology literature of Brazil (4)(5)(6)(7)(8) . Although MRI is not considered the gold standard for the evaluation of hallux valgus, because MRI scans are not acquired during weight bearing, we agree with Helito et al (9) that MRI could be used for the diagnosis of this condition, given its high prevalence and the frequent unavailability of radiographic studies during weight bearing, as stated in their study published in the previous issue of Radiologia Brasileira.…”
