A steerable guiding device: the new method in ultrasound guidance.
A working model (WM) of a newly designed device for ultrasound-guided puncture was tested. ⋯ It is believed that WM will make US-guided procedures both easier and more flexible. The performance of new device should be investigated by in vivo studies.

Potential of noncontrast electrocardiogram-gated half-fourier fast-spin-echo magnetic resonance imaging to monitor dynamically altered perfusion in regional lung.
The potential of a noncontrast, electrocardiography (ECG)-gated fast-spin-echo (FSE) MR imaging (MRI) to monitor dynamically altered regional lung perfusion was assessed in acute and temporal pulmonary embolic and airway obstruction dog models. ⋯ This noncontrast perfusion MRI may have excellent potential for continuously monitoring dynamically changed regional lung perfusion within a short time on its high spatial resolution cross-sectional images.
