A comparative analysis of myocardial strain and strain rate in cardiac computed tomography and magnetic resonance feature tracking.

ABSTRACT:

Purpose

This study investigated the feasibility of feature tracking cardiac computed tomography (CCT)-derived LV global and regional strain and its agreement with feature tracking cardiac magnetic resonance (CMR)-derived measurements.

Methods

CMR images and CCT images were acquired from 15 adult patients (50% women, mean age: 65 ± 9 years). Cardiac LV global and segmental circumferential and longitudinal strain and strain rate were assessed on CCT and CMR using feature tracking (FT) technology. Agreement between the measurements from two different modalities was evaluated using Bland-Altman analysis and intraclass correlation coefficient (ICC).

Results

Strain/strain rate analysis could be accomplished in every subject with both techniques. Agreement between CMR-FT and
