Techniques for Imaging the Vascular System,tivity of MR techniques for flow effects. “.” MR angiography (MRA) is based on the induction of signal suppression by flowing spins in combination with conventional spin-echo sequences (see “outflow effect”). This technique does not image the endoluminal vessel morphology well. Its importance is bas作者: 搖曳的微光 時間: 2025-3-22 12:47 作者: Influx 時間: 2025-3-22 14:09

Ferromagnetic items in the vicinity of the magnet are particularly hazardous. They can become dangerous missiles (“missile effect”).作者: 漸變 時間: 2025-3-22 19:54 作者: squander 時間: 2025-3-22 21:37 作者: 針葉樹 時間: 2025-3-23 04:24
Factors Affecting the Signal-to-Noise Ratio,MR signal and the noise level is characterised by the “.”.

Parallel Imaging,isition. The imaging time for all fast sequences depends crucially on the strength and switching rate of the frequency gradient and the phase encoding gradient. Very rapid switching of strong gradient fields may lead to irritation of nerve cells. This sets physiological limits to ever stronger and faster gradient systems.作者: 刀鋒 時間: 2025-3-23 10:28 作者: Ligneous 時間: 2025-3-23 14:54 作者: 我沒有命令 時間: 2025-3-23 20:26 作者: Champion 時間: 2025-3-24 00:35

MR Contrast Media,The signal intensity difference (SI-difference) of two tissues in the MR image determines the image contrast. It depends on intrinsic (body related) factors, i.e. on the different tissue properties and on extrinsic (instrument related) factors, especially the particular pulse sequence applied.作者: 全國性 時間: 2025-3-27 01:40 作者: ENDOW 時間: 2025-3-27 05:51

Spatial Encoding,an image! MRI is a tomographic procedure, i.e. sectional cuts through the body are constructed. It begins with directing the excitation pulse, not to the entire body but only towards that slice we want to investigate. How do we manage that? How do we extract from the MR signal information from where it originated inside the slice?作者: 植物群 時間: 2025-3-27 20:27 作者: 接合 時間: 2025-3-27 23:47
