The value of selective imaging of fat and water compared with proton density, T1- and T2- weighted MR sequences was studied in the course of 32 examinations on 22 primary bone tumours in various parts of the body. Fat selective images showed practically signal free areas for osteogenic tumours which could be distinguished from surrounding fat containing soft tissues. Water selective images improved definition of the tumour margin from oedema in the bone marrow. Chemical shift artefacts are avoided by these methods and therefore fat and water selective images provide better spatial resolution for identical pixel sizes.
在对22例身体各部位原发性骨肿瘤进行的32次检查过程中，研究了脂肪和水的选择性成像与质子密度、T1加权和T2加权磁共振序列相比的价值。脂肪选择性图像显示成骨性肿瘤几乎无信号区，可与周围含脂肪的软组织区分开来。水选择性图像改善了肿瘤边缘与骨髓水肿的分辨。这些方法避免了化学位移伪影，因此对于相同像素大小，脂肪和水选择性图像提供了更好的空间分辨率。
