virtual endoscopy

virtual endoscopy

computed tomographic data reconstructed in three dimensions to give information similar to that obtained with endoscopy.

virtual endoscopy

an imaging technique in which cross-sectional images acquired by computed tomography or magnetic resonance imaging are processed by computer to reconstruct a three-dimensional display similar to that seen through an endoscope.
The use of any imaging modality—e.g., ultrafast CT—to obtain 2-D images that are reconstructed to form 3-D images similar to the surface of a mucosal seen by endoscopy

virtual endoscopy

Imaging The use of an imaging modality–eg, ultrafast CT, to obtain 2-D images, which are reconstructed to form a 3-D image that is similar to endoscopy; VE does not obtain a biopsy. See Position.
