反转恢复（IR）序列的属性被认为是其在临床实践中的使用说明。分析了改变蛋白质时间、反转时间（TI）和回波时间的影响，数据编码方法，数据采集类型和图像处理方法。CNS和身体其他部位的正常表现和临床实例被用来说明该序列的许多可用选项。短TI IR序列在身体磁共振成像中具有优势，中等TI序列在脑内定位和显示对比度增强方面具有价值。长TI序列可用于儿科，并用于分离肿瘤和水肿。抑制或部分抑制脂肪和液体信号是IR序列的2个有用选项。
The properties of the inversion recovery (IR) sequence are considered and its use in clinical practice is illustrated. The effect of changing protein time, inversion time (TI) and echo time, the method of data encoding, the type of data collection and the method of image processing are analysed. Normal appearances and clinical examples of the CNS and the remainder of the body are used to illustrate the many options available with this sequence. The short TI IR sequence had advantages in magnetic resonance imaging of the body and medium TI sequences are of value in localization in the brain and in demonstrating contrast enhancement. Long TI sequences can be used in pediatrics and for separating tumor and edema. Suppression or partial suppression of fat and fluid signals are 2 useful options with IR sequences.
