[MRT sequences. Part I].
When magnetic resonance tomography is used in clinical practice a large number of different imaging techniques (sequences) are applied for the imaging. Despite this large number of sequences, which is often difficult to keep track of, all types of sequence work largely according to the same or very similar principles. In this continuing education course these principles are elaborated and the elements that make up a sequence are explained. These elements working together make it possible to assign the signals received from the receiver coil to their point of origin within the body. This first part of the further training is devoted largely to basic observations on spatial encoding of the signals, but also to the difference between 2D and 3D sequences. In addition, the techniques generally used in clinical practice for multislice imaging with 2D images are discussed in some detail.
