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.

Randomized Controlled Trial Comparative Study
Prospective comparison of noninvasive, bedside ultrasound methods for assessing central venous pressure.
To prospectively evaluate the accuracy of noninvasive central venous pressure (CVP) assessment by compression ultrasound of a forearm vein (CUS), inferior vena cava (IVC-C) and internal jugular vein collapsibility (IJV-C) compared to invasive CVP measurement (invCVP) as the gold standard. ⋯ The overall ability of CUS, IVC-C and IJV-C to assess invCVP was only moderate. CUS seems to be the preferable method if absolute CVP values are needed. IJV-C seems to be the fastest and most easily acquirable method, and thus may be especially valuable in emergency rooms.

Congenital valvar aortic stenosis (VAS) causes a pressure overload to the left ventricle. In the clinical setting, the severity of stenosis is graded by the pressure drop over the stenotic valve (pressure gradient). This parameter is dependent on the hemodynamic status and does not provide information regarding myocardial performance. This study was undertaken to reveal the potential of two-dimensional strain echocardiography (2DSTE) for the detection of myocardial functional changes due to congenital VAS in children. ⋯ 2DSTE detects alterations in myocardial function in children diagnosed with congenital VAS, whose conventional echocardiographic findings did not indicate ventricular systolic dysfunction.

The aim of the current study was to evaluate an ultrasound approach for depicting elastic recovery after stem cell application on injured Achilles tendons. ⋯ Our results indicate that autologous mesenchymal stem cell application successfully restores the mechanical properties of injured tendon tissue. Furthermore, sonoelastography makes it possible to monitor the elasticity of injured Achilles tendons.
