Our group utilizes high resolution ultrasound in order to detect, monitor, and quantify pancreatic tumors in mice. Using a VisualSonical Vevo 2100 high resolution ultrasound instrument, we can detect nascent tumors and premalignant lesions as small as half a millimeter in diameter.
On the left is an ultrasound image of the head of the pancreas of a mouse with a 4mm diameter tumor. On the right is a color-coded map of the anatomical features in this image. Key: white= skin; green= proximal duodenum; yellow- liver; red= large blood vessels; light blue= normal pancreas; dark blue= pancreatic tumor.
