Apart from the usual extracellular space, which surrounds the cells of a specific tissue it also includes the intracapillary plasma volume 1,2. It measures the space, which is occupied by the extracellular matrix Measurement. 5 The longitudinal relaxation time (T1) before and after the administration of contrast agents has been used to quantify the fraction of extracellular volume (ECV), which represents the extent of the extracellular space and can be used as a surrogate for quantifying diffuse myocardial fibrosis [1,2,3,4]. 6 Myocardial extracellular volume (ECV) reflects the proportion of extracellular matrix in the whole myocardium and expands in most pathologies affecting the heart muscle. 1 – 4 The current reference standard for noninvasive quantification of ECV is cardiac magnetic resonance imaging (MRI) using late gadolinium enhancement. 1, 3. 7 Purpose of review This review article discusses the evolution of extracellular volume (ECV) quantification using both cardiovascular magnetic resonance (CMR) and computed tomography (CT). Recent findings Visualizing diffuse myocardial fibrosis is challenging and until recently, was restricted to the domain of the pathologist. 8 INFORMATION. 9 Ecv-Basöverskott. 10
