Detecting the imaging characteristics of colorectal carcinoma invading the muscularis propria with multiphoton microscopy

The aim of this study was to examine the characteristics of the muscularis propria (mp) of human colorectum tissue with carcinoma invasion and help to advance the development for the diagnosis and therapy of early colorectal cancer. Multiphoton microscopic imaging system was used to achieve two-photon excited fluorescence (TPEF) and the second harmonic generation (SHG) images of samples respectively through the two-channel model. This work demonstrates the use of multiphoton microscopy (MPM) in obtaining clear images from thick layers of label-free tissues. Combined with endoscopy and miniaturization probes will be helpful for representing new methods to assess the functional behaviors of tissue and diagnose the early colorectal cancer in vivo.
