Abstract

Four-dimensional phase contrast MRI (4D flow) has emerged as a versatile imaging technique for comprehensive visualization and both qualitative and quantitative assessment of cardiovascular blood flow. 4D flow is a three-dimensional, time-resolved acquisition that is gated to the cardiac cycle. 4D flow provides cardiovascular velocity and flow assessment across the volume of acquisition and yields a multitude of advanced hemodynamic parameters that help to assess the impact of cardiovascular disease on flow and vice versa, guiding the clinical and surgical management of patients with congenital and acquired heart disease. In the past, lengthy scan acquisition and complex post-processing workflows hindered 4D flow adoption into routine clinical practice. Decreasing image acquisition times and improvements in post-processing techniques have made 4D flow a clinically useful tool. The purpose of this communication is to facilitate more widespread adoption of 4D flow by describing its clinical utility, technical acquisition, optimization, and post-processing in pediatric cardiovascular imaging at our center.

顺其自然：在儿童医院实施 4D 流磁共振成像计划。

四维相衬核磁共振成像（4D 流量）是一种多功能成像技术，可用于心血管血流的全面可视化、定性和定量评估。四维血流是一种三维时间分辨采集技术，与心动周期相关。4D 血流可对整个采集容积内的心血管速度和血流进行评估，并产生多种先进的血液动力学参数，有助于评估心血管疾病对血流的影响，反之亦然，从而指导先天性和后天性心脏病患者的临床和手术治疗。过去，冗长的扫描采集和复杂的后处理工作流程阻碍了 4D 流量在常规临床实践中的应用。图像采集时间的缩短和后处理技术的改进使 4D 流成为临床上有用的工具。这篇通讯的目的是通过介绍本中心在儿科心血管成像中使用 4D 流量的临床实用性、技术采集、优化和后处理，促进 4D 流量的更广泛应用。

期刊介绍： Official Journal of the European Society of Pediatric Radiology, the Society for Pediatric Radiology and the Asian and Oceanic Society for Pediatric Radiology Pediatric Radiology informs its readers of new findings and progress in all areas of pediatric imaging and in related fields. This is achieved by a blend of original papers, complemented by reviews that set out the present state of knowledge in a particular area of the specialty or summarize specific topics in which discussion has led to clear conclusions. Advances in technology, methodology, apparatus and auxiliary equipment are presented, and modifications of standard techniques are described. Manuscripts submitted for publication must contain a statement to the effect that all human studies have been reviewed by the appropriate ethics committee and have therefore been performed in accordance with the ethical standards laid down in an appropriate version of the 1964 Declaration of Helsinki. It should also be stated clearly in the text that all persons gave their informed consent prior to their inclusion in the study. Details that might disclose the identity of the subjects under study should be omitted.
