Optical coherence tomography and Doppler optical coherence tomography in the gastrointestinal tract Osiac E; Saftoiu A; Gheonea DI; Mandrila I; Angelescu RWorld J Gastroenterol 2011[Jan]; 17 (1): 15-20Optical coherence tomography (OCT) is a noninvasive, high-resolution, high-potential imaging method that has recently been introduced into medical investigations. A growing number of studies have used this technique in the field of gastroenterology in order to assist classical analyses. Lately, 3D-imaging and Doppler capabilities have been developed in different configurations, which make this type of investigation more attractive. This paper reviews the principles and characteristics of OCT and Doppler-OCT in connection with analyses of the detection of normal and pathological structures, and with the possibility to investigate angiogenesis in the gastrointestinal tract.|Animals[MESH]|Chorioallantoic Membrane/anatomy & histology[MESH]|Diagnostic Imaging/instrumentation/*methods[MESH]|Gastrointestinal Neoplasms/diagnosis/pathology[MESH]|Gastrointestinal Tract/*anatomy & histology/*pathology[MESH]|Humans[MESH]|Neovascularization, Pathologic/diagnosis/pathology[MESH]|Tomography, Optical Coherence/instrumentation/*methods[MESH]|Tomography/instrumentation/*methods[MESH] |
