To establish the distribution pattern of haematopoietic and fatty bone marrow on MRI of the proximal humerus and the scapula in correlation with age, gender and nutritive factors.
32 shoulder MR examinations (T1-weighted spin-echo and opposed-phase gradient-echo sequences) from 24 patients and 8 volunteers were analysed retrospectively. The amount of haematopoietic bone marrow within the proximal humerus and scapula was classified into four groups and was correlated with age (H-test), gender (chi 2-Test), and thickness of subcutaneous fat (H-test). The marrow distribution within 10 scapulae of cadavers over 60 years of age at death was studied.
With increasing age, the amount of haematopoietic bone marrow in the proximal humeral metaphysis tends to decrease from lateral towards medial (H-test, p = 0.3). Diaphysis and epiphysis did not show haematopoietic marrow. The amount of haematopoietic bone marrow within the paraglenoid region of the scapula also revealed a decrease with increasing age (H-test, p = 0.003). Females had higher amounts of haematopoietic marrow than males (chi 2-test, p = 0.03). The thickness of subcutaneous fat was independent of the marrow distribution.
The amount of haematopoietic bone-marrow of the shoulder girdle decreases with increasing age. The knowledge of marrow distribution patterns based upon these changes is important for shoulder MRI interpretation to prevent confusion with infiltrative disease.
确定肱骨近端和肩胛骨在MRI上造血骨髓和脂肪骨髓的分布模式，并与年龄、性别和营养因素相关联。
回顾性分析了24例患者和8名志愿者的32次肩部MR检查（T1加权自旋回波序列和反相位梯度回波序列）。将肱骨近端和肩胛骨内的造血骨髓量分为四组，并与年龄（H检验）、性别（卡方检验）和皮下脂肪厚度（H检验）相关联。研究了60岁以上死亡尸体的10块肩胛骨内的骨髓分布情况。
随着年龄的增长，肱骨近端干骺端的造血骨髓量倾向于从外侧向内侧减少（H检验，p = 0.3）。骨干和骨骺未显示造血骨髓。肩胛骨盂旁区域内的造血骨髓量也随着年龄的增长而减少（H检验，p = 0.003）。女性的造血骨髓量高于男性（卡方检验，p = 0.03）。皮下脂肪厚度与骨髓分布无关。
随着年龄的增长，肩胛带的造血骨髓量减少。基于这些变化了解骨髓分布模式对于肩部MRI解读以防止与浸润性疾病混淆很重要。
