Implication

Offers refined LV strain metrics in polar coordinates; leaves open clinical validation before routine use.

Key Points

This research aims to introduce a myocardial tagging method that uses a polar coordinate system for improved assessment of heart wall motion.
Described a myocardial tagging technique using a section-selective version of spatially modulated magnetization to create striped tags.
Applied these tags in a star pattern within the myocardium to allow for radial and angular measurements.
Used magnetic resonance imaging to visualize heart wall motion during contraction.
The new tagging method provides accurate two-dimensional strain calculations aligned with left ventricle morphology.
Angular measurements of shear and twist were successfully obtained during heart contraction.
Radial thickening measurements were enhanced due to the separation of the stripes in the myocardium.

Intervention

Myocardial tagging with magnetic resonance imaging using a section-selective version of spatially modulated magnetization resulting in striped tags (STAGs) in a star pattern

Comparator

Current methods of myocardial tagging

Outcome

Measurement of two-dimensional strain (radial thickening, shear, and twist) adapted to the morphology of the left ventriclesurrogate

A novel MRI myocardial tagging method using striped tags in a polar coordinate system allows for improved assessment of two-dimensional strain, including radial thickening and angular shear/twist.
