Medical imaging, particularly fetal MR imaging, has undergone a transformative shift with the introduction of 3 Tesla (3T) clinical MR imaging systems. The utilization of higher static magnetic fields in these systems has resulted in remarkable advancements, including superior soft tissue contrast, improved spatial and temporal resolution, and reduced image acquisition time. Despite these notable benefits, safety concerns have emerged, stemming from the elevated static magnetic field strength, amplified acoustic noise, and increased radiofrequency power deposition. This article provides an overview of fetal MR imaging at 3T, its benefits and drawbacks, and the potential safety issues.
医学影像学,特别是胎儿磁共振成像(fetal MR imaging),随着 3 特斯拉(3Tesla,3T)临床磁共振成像系统的引入,发生了革命性的转变。这些系统中更高的静态磁场强度带来了显著的进步,包括更好的软组织对比度、更高的空间和时间分辨率,以及更短的图像采集时间。尽管有这些显著的优势,但也出现了一些安全问题,这些问题源于增强的静态磁场强度、放大的噪声和增加的射频功率沉积。本文概述了 3T 下的胎儿磁共振成像,包括其优缺点以及潜在的安全问题。
