Randomized Controlled Trial
Dynamic needle tip positioning - ultrasound guidance for peripheral vascular access. A randomized, controlled and blinded study in phantoms performed by ultrasound novices.
The application of ultrasound-guidance for peripheral venous access is gaining popularity. It is possible to produce a short axis or a long axis sonographic view of the target vessel and apply an out-of-plane or in-plane needle tip approach. Our aim was to present the dynamic needle tip positioning technique and to estimate which approach is the most accurate for inserting the needle tip into the center of the target vessel. ⋯ The combined short axis and out-of-plane technique using dynamic needle tip positioning had a higher success rate and a shorter distance between the center of the target vessel and the needle tip compared to the combined long axis and in-plane technique.

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.

Review Comparative Study
Ultrasound guidance for neuraxial analgesia and anesthesia in obstetrics: a quantitative systematic review.
The aim of this quantitative systematic review was to assess the efficacy and safety of ultrasound-guided neuraxial blocks in obstetric analgesia and anesthesia. ⋯ There is some evidence that ultrasound guidance may improve the efficacy and safety of neuraxial blocks in obstetrics. If technical difficulties are anticipated, ultrasound may lower the rate of procedure-related adverse events.
