Partitioning of the Magnetization into Configurations,an method and its fundamental artifacts, like those due to .. or .. decay and resonance offset, could be explained. In this chapter it will be shown that additional information can be obtained by looking at the partitioning of the magnetization vector in “configurations” (or “base states” or “coherences”), characterized by their dephasing state.

Contrast and Signal-to-Noise Ratio,3 a survey is given of the basic physics of relaxation. This survey is not meant to be complete (there is excellent literature available [1, 4.2]) but it is also needed in order to introduce two techniques which influence the values of the relaxation constants, namely magnetization transfer (Sect. 6.3.3) and contrast agents (Sect. 6.3.4).

In many cases the problems of patient motion can be circumvented by applying ECG triggering and/or respiratory motion detection, but in cases of abdominal imaging, heavy arrythmia of the heart function, fast dynamic processes, or very ill and traumatized patients, very fast scanning is necessary.

Magnetic Resonance Imaging: A Historical Introduction,wever, there is a time gap of almost thirty years between the discovery of nuclear magnetic resonance simultaneously and independently by Bloch [1] and by Purcell [2] in 1946 and the first imaging experiments in the 1970s by Lauterbur and by Damadian.

Conventional Imaging Methods, the elements that we need in order to discuss the conventional scan methods called Spin Echo (SE) and Field Echo (FE). For better understanding, and also as a preparation for the discussion of the modern fast and ultra-fast methods, we introduce the concept of . space. The fundamental artifacts of
