Imaging Techniques of Magnetic Resonance Angiographyst (PC, also called phase-sensitive) techniques. TOF in its two-or three-dimensional mode is very robust, fast, and easy to apply. This chapter will describe the basics of TOF together with the techniques employed in its realization. Shortcomings and possible artifacts will be discussed, and adviceCongeal 发表于 2025-3-25 12:09:41

Postprocessing Techniques contrast, is usually applied in a three-dimensional format to obtain a series of slices or a volume data set which is interpreted as a series of thin contiguous slices or partitions. First one can look through individual slices or calculate multiplanar reconstructions from interesting vessel region火花 发表于 2025-3-25 23:36:01
Hardware Configurationserformance, and proper software implementations. In this chapter a short overview is given of those hardware components that affect the performance of MRA. Basically all of the various MRA techniques require optimal hardware conditions, and great benefits have derived from recent improvements, suchmitten 发表于 2025-3-26 01:52:23
Quantification of Blood Flow of flow dynamics. Reflecting the inherent motion sensitivity of MRI with regard to both amplitude and phase, two different MR techniques are available for flow measurements: one is based on the influence of motion on signal amplitude, the other on the influence of motion on signal phase. They can b分散 发表于 2025-3-26 06:33:36
