Implication

Demonstrates in vivo 2D strain rate feasibility with 1D agreement; leaves open clinical utility pending prospective validation.

Key Points

To assess the feasibility of measuring two-dimensional strain rate in the human heart in vivo using high-frame-rate ultrasonic imaging.
Acquired ultrasonic B-mode data at a high temporal resolution of 3.8 ms.
Tracked radiofrequency (RF) signal patterns across two-dimensional sector images off-line to estimate myocardial strain rate.
Successfully tracked both axial and lateral tissue motion and computed corresponding 2D strain rates in vivo.
Achieved good agreement between 2D strain rate measurements and established 1D ultrasonic techniques.
