Figure 4From: Comparison of 2D and 3D calculation of left ventricular torsion as circumferential-longitudinal shear angle using cardiovascular magnetic resonance taggingBland-Altman plots for the base-apex (a), base-mid (b) and mid-apex (c) torsion values of the subjects, using T 2D . The difference between the values from both methods increases linearly when the average torsion value becomes higher.Back to article page
