Hyperemic osteoporosis can be detected early on serial roentgenograms by loss of the fine trabecular pattern. Maintenance of the normal pattern may be a sign of avascular necrosis. During repair, the fine trabeculae reconstitute poorly, and new bone deposits on the remaining primary heavier trabeculae, leaving a permanent coarse pattern as an indication of former osteoporosis.
充血性骨质疏松可通过连续X线片上细微骨小梁模式的丧失早期检测到。正常模式的维持可能是缺血性坏死的迹象。在修复过程中，细微骨小梁重建不佳，新骨沉积在剩余的主要较粗骨小梁上，留下永久性的粗大模式，作为既往骨质疏松的指征。
