Objective
This study evaluates the correlation between the sonographic features and the nodal fine‐needle aspiration thyroglobulin (FNA‐Tg) in papillary thyroid carcinoma (PTC) patients with the recurrent/persistent lymph node for the purpose of the reasonable selection of lymph nodes.
Methods
This study prospectively contained PTC patients with the suspicious cervical lymph nodes in one medical...
We demonstrate a Faraday laser at Cs-D2 resonance line 852 nm using a Cs Faraday optical filter as frequency-selecting element. In contrast to typical diode laser with high stability of the emission frequency by additional control systems, our Faraday laser offers stable output frequency exactly set by the peak transmission frequency of the Cs 852 nm Faraday optical filter. The system works stably...
