BiovalleyBIOON/-- Professor Tian Chao's team in the Department of Precision Machinery and Precision Instruments at the Chinese University of Science and Technology, Chinese Academy of Sciences, has made some progress in medical photoacoustic imagingThey improved the image quality and three-dimensional structure of photoacoustic imaging and applied it to the body's outpost lymphatic imageThe studies were published in the IEEE Journal of Biobioengineering, Physical Reviewapp
lied, and Journal of Biophotonicsoutpost lymph node biopsy (SLN) is currently the standard method forstages ofbreast cancer, including preoperative lymph node tracing and intraoperative lymph node biopsy image guidanceHowever, the existing image guidance technology has harmful ionizing radiation, high cost, image depth difference and other limitationsphoto source: To solve these problems, Professor Tian's team proposed a contract agent-enhanced photoacoustic imaging method, using clinically approved carbonnano-
particles (CNPs) as an contrast agent to track SLN and guide a fine needle puncture biopsy without radiationresearchers injected carbonnano
particles into the front claws of live mice to stain SLN Subsequently, in real-time simultaneous photoacoustic and ultrasonic dual-mode imaging in the rat armpit area, SLN was tracked to guide biopsy experiments have shown that photoacoustics can provide high-quality image guidance for lymph nodes biopsies with high resolution and high signal-to-noise ratio imaging to show lymph nodes, lymph nodes, needles, etc spectral analysis shows that CNPs are superior to contrast in photo absorption coefficient, photobleaching and photoacoustic conversion efficiency, such as pyridine green, methylene blue and other contrast agents This is a good tracer to identify SLN photoacoustic imaging and image-guided biopsy of the new contrast agent this study provides a practical fine needle puncture biopsy for tracing and image guidance of single-sided clavicle network, which lays the foundation for the transformation of clinical light sound single-sided clavicle network imaging (BioValleyBioon.com) References: Medical Imaging Improves Cancer Staging Songde Liu et al, In Vivoacoustic Photo Sentinel Lymph Imaging Clinical -approved Carbon Nanoparticles, IEEE Transactions on Biomedicaling (2019) DOI: 10.1109/TBME.2019.2953743
