The purpose of this study was the assessment of the diagnostic value of fat-suppression T2-weighted images for a variety of bone marrow lesions. We performed 40 studies of the axial or appendicular skeleton in 33 patients (age range 4-80 years) with neoplastic, inflammatory or traumatic lesions with a 0.5 T system (Gyroscan T5, Philips Medical Systems, Best, The Netherlands). Fat-suppression T2-weighted images [turbo spin echo (TSE) with spectral presaturation with inversion recovery (SPIR)] were obtained in addition to the routine T1-weighted SE and T2-weighted TSE sequences. Fat-suppression TSE T2-weighted images were better than standard TSE T2-weighted images in 25 studies. In 11 of them demonstration and characterization of the lesions (known from T1-weighted images) was possible only after fat suppression. In the other 14 patients demonstration of the full extent of the lesion especially to the nearby soft tissues was possible only after fat suppression. In 13 studies no advantage was conferred by SPIR, whereas in two instances T2-weighted images were better. Fat-suppression T2-weighted images are diagnostically useful in a variety of lesions of the musculoskeletal system, but their limitations should be known.
本研究的目的是评估脂肪抑制T2加权图像对各种骨髓病变的诊断价值。我们使用0.5T系统（荷兰贝斯特飞利浦医疗系统公司的Gyroscan T5）对33例年龄在4至80岁之间患有肿瘤、炎症或创伤性病变的患者进行了40次轴向或附属骨骼检查。除了常规的T1加权SE序列和T2加权TSE序列外，还获取了脂肪抑制T2加权图像[采用频谱预饱和反转恢复（SPIR）的快速自旋回波（TSE）]。在25次检查中，脂肪抑制TSE T2加权图像优于标准TSE T2加权图像。其中11例中，只有在脂肪抑制后才能显示和鉴别病变（从T1加权图像已知）。在另外14例患者中，只有在脂肪抑制后才能显示病变的全部范围，尤其是邻近软组织的范围。在13次检查中，SPIR没有优势，而在2例中T2加权图像更好。脂肪抑制T2加权图像对肌肉骨骼系统的各种病变具有诊断价值，但应了解其局限性。
