Multicenter Study
Assessment of ultrasound acoustic artifacts in patients with acute dyspnea: a multicenter study.
Recent reports indicate that numerical assessment of B-lines during transthoracic ultrasound may aid the differential diagnosis of acute diffuse pleuropulmonary disorders. ⋯ Our results demonstrate that there are a significant higher number of B-lines in the lungs of patients with dyspnea compared to healthy subjects and to pneumonectomized patients. Nevertheless, the quantification of B-lines does not make any significant contribution to the differential diagnosis of dyspnea.

Multicenter Study
Multicenter evaluation of a new laser guidance system for computed tomography intervention.
To measure the accuracy of laser-guided punctures and to evaluate the usefulness of the developed laser-guided system. ⋯ Different users at four different centers found the laser guidance system useful and easy to use. A high level of accuracy of the puncture angle was obtained in most cases.
