To define age-specific patterns of distribution of red and yellow marrow about the shoulder.
Red and yellow marrow distribution was reviewed on magnetic resonance images of 189 subjects aged 15-69 years. Double-echo and fast spin-echo, gradient, and short inversion time inversion recovery pulse sequences were used. The acromion, glenoid, and proximal humeral epiphysis, metaphysis, and diaphysis in each shoulder were graded semiquantitatively and qualitatively.
There was a wide variation in the normal pattern of red-yellow marrow distribution both among subjects and among locations. All five anatomic locations showed an orderly progression from greater to lesser amounts of red marrow with increasing age. Many of the subjects had focal subchondral red marrow in the epiphysis, which was associated with patient age (P = .0001) and gender (P = .04).
Knowledge of normal patterns of marrow distribution can prevent their being misinterpreted as marrow-based disease.
确定肩部红骨髓和黄骨髓的年龄特异性分布模式。
回顾了189名年龄在15至69岁之间受试者的肩部磁共振成像（MRI），观察红骨髓和黄骨髓的分布情况。采用了双回波、快速自旋回波、梯度回波和短反转时间反转恢复脉冲序列。对每个肩部的肩峰、关节盂、肱骨近端骨骺、干骺端和骨干进行半定量和定性分级。
红骨髓和黄骨髓的正常分布模式在受试者之间和部位之间存在很大差异。随着年龄增长，所有五个解剖部位的红骨髓量均呈现从多到少的有序变化。许多受试者的骨骺有局灶性软骨下红骨髓，这与患者年龄（P = 0.0001）和性别（P = 0.04）有关。
了解骨髓分布的正常模式可避免将其误诊为骨髓疾病。
