The aim of our study was to evaluate the efficacy of microwave (MW) ablation of liver metastases guided by B-mode ultrasound (US) and contrast-enhanced US (CEUS). ⋯ CEUS-guided MW ablation of liver metastases is an efficient and safe ablation technique with several advantages compared to other ablation modalities.

Comparative Study
[Automated breast ultrasound vs. handheld ultrasound: BI-RADS classification, duration of the examination and patient comfort].
Automated breast ultrasound (ABUS) is a potentially valuable adjunct to mammography in breast cancer screening. The reliability and the inter-observer variability in the BI-RADS classification, compared to handheld ultrasound (US), as well as the duration of the examination and patient comfort have only been investigated in a limited number of papers to date. ⋯ ABUS examinations focusing on the BIRADS classification have low inter-observer variability, compared to handheld US. The sensitivity of ABUS did not differ significantly from handheld US.

The purpose of this study was the conception and evaluation of a standardized and reliable assessment tool in the OSCE format to measure the performance and practical skills of abdominal ultrasound users in PGME. ⋯ The homogeneous distribution of item difficulties provides an opportunity for designing different OSCE versions with different levels of reliability. Several options to adjust the cut-off values, the choice of the examined contents and factors that influence the examinees' acceptance of this assessment tool for PGME or CME ultrasound courses are discussed. Overall, the values of reliability and accuracy of this assessment tool are high enough to be used also for high-stakes examinations in the field of abdominal ultrasound.

Transcranial Doppler (TCD) can be used as a confirmatory test in brain death. The aim was to present the usefulness of TCD in brain death confirmation. ⋯ TCD is a favorable confirmatory test for cerebral circulatory arrest in brain death diagnosis.
