UltrasoundoftheHand-Wrist-北京大学第三医院肌骨超声学校
High-resolution ultrasound is capable of detecting foreign bodies of practically any composition. The purpose of this study was to determine in a controlled manner the sensitivity and specificity of ultrasound in the diagnosis of foreign bodies in the hand. Each of 15 fresh-frozen cadaver hands was...
A secondary aim was to assess the function of components of the DH. Sixteen embalmed hands were evaluated by MRI and ultrasound before being dissected. Each hand was photographed during each stage of dissection. Secondly we evaluated the role of the different structures of the DH in the ...

Quantitative Doppler ultrasound of the carotid artery has been proposed as an instantaneous surrogate for monitoring rapid changes in left ventricular output. Tracking immediate changes in the arterial Doppler spectrogram has value in acute care settings such as the emergency department, operating room and...
The movement of the hand-held probe produces uneven pressure on the target surface. When the pressure is high, the noise of the B-scan increases. Therefore, in the acquisition process, the moving direction of the B-scan should be parallel to the target surface as much as possible, and ...
The aim of this research is to evaluate the diagnostic performance of BI-RADS classification in comparison with new semi-automatic software Resona R9, Mindray, “SmartBreast” and strain elastography (SE), point shear wave (pSWE), and 2D shear wave (2D SWE) Elastography for breast lesion ...
