To evaluate the reliability of shear wave ultrasound elastography (SWE) in the neck. ⋯ Intra- and inter-rater reliability of SWE is fair to excellent according to ICCs. SWE reliability is influenced appreciably by acquisition technique. Nevertheless, CORs for SWE are not negligible. To determine whether these results are acceptable clinically, further research is required to establish SWE stiffness values of normal and pathological tissues in the neck.

Echocardiographic Tissue Doppler Imaging (TDI) has been proposed for the differentiation of pathological left ventricular hypertrophy (e. g. hypertrophic cardiomyopathy, HCM) and physiologic left ventricular hypertrophy (athlete's heart). The aim of this study was the TDI analysis of the systolic (S') and early diastolic (E') velocities in patients (pts.) with non-obstructive hypertrophic cardiomyopathy (HCM) and in top-level athletes in consideration of the previously published cut-off values (S' < 9 cm/s, E' < 9 cm/s). ⋯ Tissue Doppler Imaging of the systolic and early diastolic velocity of the mitral annulus might be helpful as a promising additional method for the echocardiographic differentiation between pathological and physiologic left ventricular hypertrophy.
