What is high-frequency ultrasound?
High-frequency ultrasound is a non-invasive imaging technique that uses sound waves to visualize internal structures.
How is the mouse prepared for imaging?
The mouse is anesthetized, positioned on a heated platform, and prepared with ultrasound gel applied to the neck area.
What are the benefits of using HFUS for lymph node imaging?
HFUS provides detailed images of lymph node morphology and allows for real-time monitoring of blood flow.
Can this method be used for other diseases?
Yes, it can be adapted to study lymphadenopathy in various conditions, including infections and autoimmune diseases.
What is the significance of image-guided biopsy?
Image-guided biopsy allows for precise sampling of lymph nodes, improving the accuracy of histological evaluations.
How does the imaging process work?
The imaging process involves scanning the neck region with a high-frequency transducer to visualize lymph nodes.
