Key result
Doppler tissue imaging accurately quantified left ventricular maximal torsion, demonstrating a strong correlation with tagged magnetic resonance imaging (r=0.95, P<0.0001).
Why the study?

Observational (n=20)
Does Doppler tissue imaging (DTI) accurately quantify left ventricular torsional deformation compared to tagged MRI in patients?
Effect estimate: r=0.95
p-value: p=<0.0001
Doppler tissue imaging provides an accurate, noninvasive method for quantifying left ventricular torsional deformation, correlating closely with the reference standard of tagged MRI.

DTI supports noninvasive LV torsion assessment; cross-sectional data leave open prospective outcome validation before clinical adoption.
Notomi et al. (2005) reported an observational. Doppler tissue imaging (DTI) vs. Tagged magnetic resonance imaging (MRI) was evaluated on Correlation of left ventricular rotation and torsion between DTI and tagged MRI (r=0.95, p=<0.0001). Doppler tissue imaging accurately quantified left ventricular maximal torsion, demonstrating a strong correlation with tagged magnetic resonance imaging (r=0.95, P<0.0001).
