The assessment of wall motion abnormalities such as hypokinesia or dyskinesia and the identification of their extent as well as their degree of severity allow an accurate evaluation of several ischemic heart diseases and an early diagnosis of heart failure. These dysfunctions are usually revealed by a drop of contraction indicating a regional hypokinesia or a total absence of the wall motion in case of akinesia. The discrimination between these contraction abnormalities plays also a significant role in the therapeutic decision through the differentiation between the infarcted zones, which have lost their contractile function, and the stunned areas that still retain viable myocardial tissues. The lack of a reliable method for the evaluation of wall motion abnormalities in cardiac imaging presents a major limitation for a regional assessment of the left ventricular function. In the past years, several techniques were proposed as additional tools for the local detection of wall motion deformation. Among these approaches, the parametric imaging is likely to represent a promising technique for the analysis of a local contractile function. The aim of this paper is to review the most recent techniques of parametric imaging computation developed in cardiac imaging and their potential contributions in clinical practice.
对诸如运动减弱或运动障碍等壁运动异常的评估以及对其范围和严重程度的识别，有助于准确评估多种缺血性心脏病并早期诊断心力衰竭。这些功能障碍通常表现为收缩力下降，提示局部运动减弱，或在运动不能的情况下壁运动完全消失。这些收缩异常之间的区分在治疗决策中也起着重要作用，通过区分失去收缩功能的梗死区域和仍保留存活心肌组织的顿抑区域。在心脏成像中缺乏评估壁运动异常的可靠方法，这对左心室功能的局部评估构成了主要限制。在过去几年中，提出了几种技术作为局部检测壁运动变形的附加工具。在这些方法中，参数成像可能是一种用于分析局部收缩功能的有前途的技术。本文的目的是回顾心脏成像中最新开发的参数成像计算技术及其在临床实践中的潜在贡献。
