The double-density sign, seen on radionuclide bone scans, is described for diagnosing osteoid osteomas and for localizing the nidus. Its use in differentiating the nidus of an osteoid osteoma from osteomyelitis is also described. The utility of computed tomography in localization of the nidus is also illustrated. The double-density sign was helpful in diagnosing seven cases of surgically confirmed osteoid osteoma.
放射性核素骨扫描中出现的双密度征可用于诊断骨样骨瘤并确定瘤巢位置。本文还介绍了其在鉴别骨样骨瘤瘤巢与骨髓炎方面的应用。同时也展示了计算机断层扫描在确定瘤巢位置上的作用。双密度征有助于诊断7例经手术证实的骨样骨瘤。
