Most cases of esophageal cancer can be prevented if detected early at the precancerous high-grade dysplasia stage in patients presenting with Barrett's esophagus, a condition that almost always precedes this form of cancer. Here, Qiu and colleagues have developed a multispectral imaging system that uses endoscopic polarized scanning spectroscopy to perform rapid optical scanning and imaging of the entire esophageal surface, providing a diagnosis in near real time.
