Light and sound - emerging imaging techniques for inflammatory bowel disease

Figure 1 Overview of existing and emerging endoscopic technologies to visualize macroscopic or microscopic features of the intestine. Macroscopic technologies include: high-definition endoscopy, wide-view full-spectrum endoscopy, chromoendoscopy, and autofluorescence endoscopy. Microscopic technologies include: endocytoscopy, confocal laser endoscopy, multiphoton endoscopy, and molecular imaging endoscopy. A detailed description for each modality is given in the text.

Figure 2 Overview of existing and emerging ultrasound transabdominal and endoscopic technologies for visualizing the intestine. Besides B-mode and Doppler, technologies include: contrast-enhanced ultrasound, ultrasound molecular imaging, and elastography. A detailed description for each modality is given in the text.
