Comparative Study
[Ultrasound versus MRI in preventive examinations - a retrospective analysis of 833 patients].
The benefit of ultrasound in comparison with full-body MRI during a medical checkup in preventive health care was examined with regard to the detection of cardiovascular risk factors, metabolic syndrome, malignant tumors and further relevant findings. ⋯ For the detection of lifestyle-dependent diseases such as atherosclerosis and metabolic syndrome, ultrasound examination was more sensitive than MRI, and the same was true for the early detection of thyroid diseases. For the detection of malignant abdominal tumors, both methods were equally sensitive. Whole-body MRI can additionally detect pathological changes in the head, lungs and colon.

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.
