2024年5月4日 · Spin-echo pulse sequences are one of the earliest developed and still widely used (in the form of fast spin echo) of all MRI pulse sequences. The pulse sequence timing …

How is a spin echo generated? A single RF pulse generates a free induction decay (FID), but two successive RF pulses produce a spin echo (SE). The time between the middle of the first RF …

A spin echo sequence has two essential parameters: TR and TE. TR is the time interval between two successive 90° RF waves. It conditions the longitudinal relaxation of the explored tissues …

In this review article, the principles of the spin echo formation are dem-onstrated on which the generation of the fundamental image contrasts T1, T2, and proton density is based. The basic …

2021年10月10日 · A spin echo sequence aims to remove the effects of the static field (T2*) but leave the tissue characteristic T2 effect. a. Application of 90° RF pulse. 1. A 90° RF pulse is …

2022年10月31日 · A guide to the spin echo MRI sequence, covering key parameters, chronogram, advantages, limitations, and when to use an SE sequence.

2016年6月7日 · Spin echo (SE) imaging is a class of imaging sequences that utilize an SE to form an image. This will be introduced in the context of k-space imaging requirements (which are …
