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.

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.

Sudden retinal blindness is a common complication of temporal arteritis (TA). Another common cause is embolic occlusion of the central retinal artery (CRA). The aim of this prospective study was to examine the diagnostic value of hyperechoic material in the CRA for the exclusion of vasculitis as a cause. The authors used orbital color-coded sonography (OCCS) for the detection of hyperechoic material. ⋯ The detection of the "spot sign" specifically minimizes the probability of TA as a reason for sudden blindness.
