摘要

目的:评价快速3D轮(Fast 3Dw)技术在脑磁共振血管造影(MRA)中的应用效果,并与常规平行成像(PI)技术进行比较。主要目的是确定Fast 3Dw是否可以减少脑动脉瘤患者的检查时间,同时保持图像质量和诊断准确性。方法:本回顾性研究包括50例未破裂的脑动脉瘤患者,他们在3T磁共振成像扫描仪上使用PI或Fast 3Dw技术进行3D飞行时间MRA。通过信噪比(SNR)、噪声对比比(CNR)、动脉瘤直径和血管直径对图像质量进行定量评估。定性图像评估包括血管清晰度、伪影和诊断置信水平,并采用5分制进行评估。采用t检验、Wilcoxon符号秩检验和加权kappa统计进行统计比较。结果:Fast 3Dw的平均检查时间(171.5±4.9 s)明显短于PI(383.8±13.2 s); p结论:与PI相比,Fast 3Dw技术在保持大脑MRA图像质量和诊断准确性的同时显著缩短了检查时间。在临床实践中,该方法可能是常规脑磁共振成像的可行替代方法。

Fast 3D wheel acquisition versus conventional parallel imaging in cerebral magnetic resonance angiography for the evaluation of intracranial aneurysms : Original Article.

Purpose: This study aimed to evaluate the effectiveness of the Fast 3D wheel (Fast 3Dw) technique in cerebral magnetic resonance angiography (MRA) and compare it with the conventional parallel imaging (PI) technique. The primary objective was to determine whether Fast 3Dw could reduce the examination time while maintaining image quality and diagnostic accuracy in patients with cerebral aneurysms.

Methods: This retrospective study included 50 patients with unruptured cerebral aneurysms who underwent 3D time-of-flight MRA using either PI or Fast 3Dw techniques on a 3T magnetic resonance imaging scanner. The image quality was quantitatively assessed using the signal-to-noise ratio (SNR), contrast-to-noise ratio (CNR), aneurysm diameter, and vessel diameter. Qualitative image assessments included vascular clarity, artifacts, and diagnostic confidence level and were evaluated using a 5-point scale. Statistical comparisons were performed using t-tests, Wilcoxon signed-rank tests, and weighted kappa statistics.

Results: The mean examination time for Fast 3Dw (171.5 ± 4.9 s) was significantly shorter than that for PI (383.8 ± 13.2 s; p < 0.05). Fast 3Dw exhibited a significantly higher SNR (50.0 ± 14.2) than PI (46.6 ± 12.9; p < 0.05), while CNR showed no significant difference between the two techniques. No significant differences in aneurysm diameters and vessel diameters were observed between the two methods. Qualitative evaluations demonstrated no significant differences in vascular clarity, artifacts, and diagnostic confidence levels between the two methods.

Conclusion: The Fast 3Dw technique significantly reduces examination time while maintaining image quality and diagnostic accuracy in cerebral MRA compared to PI. This method may be a viable alternative for routine cerebral MRA in clinical practice.

期刊介绍: Neuroradiology aims to provide state-of-the-art medical and scientific information in the fields of Neuroradiology, Neurosciences, Neurology, Psychiatry, Neurosurgery, and related medical specialities. Neuroradiology as the official Journal of the European Society of Neuroradiology receives submissions from all parts of the world and publishes peer-reviewed original research, comprehensive reviews, educational papers, opinion papers, and short reports on exceptional clinical observations and new technical developments in the field of Neuroimaging and Neurointervention. The journal has subsections for Diagnostic and Interventional Neuroradiology, Advanced Neuroimaging, Paediatric Neuroradiology, Head-Neck-ENT Radiology, Spine Neuroradiology, and for submissions from Japan. Neuroradiology aims to provide new knowledge about and insights into the function and pathology of the human nervous system that may help to better diagnose and treat nervous system diseases. Neuroradiology is a member of the Committee on Publication Ethics (COPE) and follows the COPE core practices. Neuroradiology prefers articles that are free of bias, self-critical regarding limitations, transparent and clear in describing study participants, methods, and statistics, and short in presenting results. Before peer-review all submissions are automatically checked by iThenticate to assess for potential overlap in prior publication.
