  • Look Inside

 Virtual endoscopy (VE) has developed mainly as a non-invasive technology for detection of neoplastic lesions of the colon. This technique is considered as a promising examination instrument, along with marked development of CT diagnostic machinery. Although axial CT has been used for the diagnosis of the pathology of inflammatory bowel disease, VE has not achieved its due recognition because endoscopy and conventional radiography maintain their usefulness in these fields. In Crohn's disease (CD) mucosal lesions (ulcer and cobblestoning), stenosis and fistula are usually encountered and extraluminal lesions (inflammatory mass, lymphadenopathy, mesenteric fatty inflammation and abscess) often accompany them. In this review, using the literature and our own experiences, the clinical value of VE is analyzed to find out how VE depicts these intraluminal and extraluminal lesions in CD. From our own study VE is considered useful for visualizing the proximal lumen of the stenosis, but there are very few studies which emphasize the efficacy of VE in the diagnosis of CD. From an extensive review of the literature, it can be seen that VE is not considered as especially effective for diagnosing precisely the intraluminal lesions in CD. However, because CT instruments for diagnosing CD are being developed rapidly ulcerative lesions of CD will be precisely diagnosed by VE in the near future. At that time VE will be used effectively for patients with CD.
