CISS (Constructive Interference in Steady State) MRI is an advanced imaging technique derived from the TrueFISP sequence. It utilizes specialized radiofrequency pulses, gradient echo sequences, and a T2-weighted 3D gradient echo technique to …

The 3D CISS sequence is strongly recommended in an MRI imaging protocol for the study of HFS, in combination with 3D TOF magnetic resonance angiography (MRA), to obtain fine anatomical details of the various structures with a good cisternographic effect.

FIESTA-C/CISS is currently the sequence of choice for CSF-cisternography for visualizing cranial nerves at the skull base. When used in the 3D mode, it provides high signal from CSF based on T2/T1 contrast and high spatial resolution. Furthermore, like FIESTA/TrueFISP, it has inherent flow compensation because of its perfectly balanced gradients.

Three-dimensional (3D) constructive interference in steady state (CISS) is a fully refocused steady-state gradient-echo MRI sequence. This sequence is now freely available and is frequently used in MRI to investigate a wide range of pathologies when routine MRI sequences do not provide the desired anatomic information.[ 1 ]

3d-ciss是一种高空间分辨率、再聚焦梯度回波的mri序列，并加用流动补偿技术，消除干扰伪影 。3d-ciss序列与3d-space序列相似，也可以清楚地判断出三叉神经的起源、分支以及走向。

This article reviews the effectiveness of three-dimensional constructive interference in steady-state (3D-CISS) MRI in diagnosing the exact location, degree of neurovascular conflict responsible for classical as well as atypical TN and possible pre-treatment evaluation and treatment outcome.

回顾性分析62例以三叉神经痛为主要症状患者的颅脑MRI常规序列和3D-CISS序列图像，其中12例加做增强扫描，对比分析MRI 3D-CISS序列和常规平扫序列对三叉神经相关病变 (主要包括三叉神经脑池段周围血管压迫或推移、实性肿瘤和肿瘤样病变)的显示情况，并与手术结果对照。 手术探查48例发现责任血管；术前MRI 3D-CISS序列诊断三叉神经脑池段周围血管压迫或推移46例，3D-CISS序列显示与手术探查符合率达95.83%；常规序列无法显示三叉神经脑池段周围血管压迫 …

2009年9月15日 · In the current study, we aimed to compare the diagnostic efficacies of phase-contrast magnetic resonance imaging (PC-MRI) and three-dimensional constructive interference in steady-state (3D-CISS) sequence over detection of aqueductal stenosis (AS) on the basis of contrast-enhanced magnetic resonance cisternography (MRC).

Three-dimensional (3D) constructive interference in steady state (CISS) is a gradient-echo MRI sequence that is used to investigate a wide range of pathologies when routine MRI sequences do not provide the desired anatomic information. The increased sensitivity of the 3D CISS sequence is an outcome …

2022年11月21日 · The 3D CISS sequence is strongly recommended in an MRI imaging protocol for the study of HFS, in combination with 3D TOF magnetic resonance angiography (MRA), to obtain fine anatomical details of the various structures with a good cisternographic effect.
