Cardiac myofiber orientation is a crucial determinant of the distribution of myocardial wall stress. Myofiber orientation is commonly quantified by helix and transverse angles. Accuracy of reported helix angles is limited. Reported transverse angle data are incomplete. We measured cardiac myofiber orientation postmortem in five healthy goat hearts using magnetic resonance-diffusion tensor imaging. A novel local wall-bound coordinate system was derived from the characteristics of the fiber field…

Image-Based Investigation of Human in Vivo Myofibre Strain

This study provided the first quantitative evidence of homogeneity of ES my ofibre strain using minimally-invasive medical images of the human heart and demonstrated that image-based modelling framework can provide detailed insight to the mechanical behaviour of the myofibres, which may be used as a biomarker for cardiac diseases that affect cardiac mechanics.

Transmural heterogeneity of diffusion anisotropy in the sheep myocardium characterized by MR diffusion tensor imaging.

Results indicate that FA remains relatively constant from the epicardium to the midwall and then decreases steadily toward the endocardium, and suggest a role for MR diffusion tensor imaging in characterization of not only fiber orientation but, also, other tissue parameters, such as the extracellular volume fraction.

Assessment of Myofiber Orientation in High Resolution Phase-Contrast CT Images

Although the high-resolution imaging and analysis show that the myocardium in an individual is more complex than often assumed, the common rule-based model is generated, simulating fiber angles distribution for the given geometry.

A high-resolution cardiovascular magnetic resonance diffusion tensor map from ex-vivo C57BL/6 murine hearts

This tensor map has the potential to yield an accurate mean representation and identification of common or unique features of the cardiac myocyte architecture, to establish a baseline standard reference of DTI indices, and to improve detection of biomarkers, especially in pathological states or post-transgenetic modifications.

Left Ventricular Flow Dynamics and Transmural Gradients in Myofiber Shortening with MRI-Tagging

A method to assess transmural differences in myofiber shortening, using MRI-tagging of the heart, appears sensitive to distinguish patients with aortic stenosis from healthy volunteers.



Imaging myocardial fiber architecture in vivo with magnetic resonance

Methods are presented to image the fiber architecture of the human myocardium in vitro and in vivo, and the results show classic features of ventricular myoarchitecture including the continuous endocardial to epicardial variation of fiber helix angles.

Anisotropy of water diffusion in the myocardium of the rat.

These data suggest that myocardial water diffusion is essentially unrestricted parallel to the myofibers and show that failure to measure the complete diffusion tensor may lead to substantial underestimates of diffusion anisotropy in the myocardium.

Magnetic resonance myocardial fiber-orientation mapping with direct histological correlation.

Data strongly support the hypothesis that the eigenvector of the largest MR diffusion tensor eigenvalue coincides with the orientation of the local myocardial fibers and underscore the potential of MR imaging as a noninvasive, three-dimensional modality to characterize tissue fiber architecture.

Histological validation of myocardial microstructure obtained from diffusion tensor magnetic resonance imaging.

Diffusion tensor magnetic resonance imaging studies performed in a total of seven hearts support a level of organization beyond the myofiber, the recently described laminar organization of the ventricular myocardium.

Reconstruction of Cardiac Ventricular Geometry and Fiber Orientation Using Magnetic Resonance Imaging

Evidence is presented suggesting that diffusion tensor tertiary eigenvectors may specify the orientation of ventricular laminar sheets in cardiac ventricles, and DTMRI-based estimates of fiber orientation are shown to agree closely with those measured using histological techniques.

Fiber Orientation in the Canine Left Ventricle during Diastole and Systole

The wall has a well-ordered distribution of fiber angles varying from about 60° (from the circumferential direction) at the inner surface to about –60° on the outer surface, and the greatest change in angle occurs at the two surfaces (endocardial and epicardial).

Cardiac diffusion tensor MRI in vivo without strain correction

This paper presents a method to obtain accurate diffusion data without strain correction, and shows that in humans, the strain prediction of the sweet spots and the locations determined by the diffusion trace show a high correlation.

Direct histological validation of diffusion tensor MRI in formaldehyde‐fixed myocardium

Diffusion tensor MRI is emerging as a rapid, nondestructive method to map myocardial fiber organization and shows it also accurately maps the fibrous architecture of formalin‐fixed hearts.
