CT ENTEROGRAPHY THESIS

Improved visualisation of mucosal lesions compared with conventional CT. Boudiaf et al classified small bowel distension using a grading system based on diameters of jejunum and ileum graded 0—3 where 0 was for no distension and 3 was optimal distension. As a result, a single CT enterography may eliminate the need for multiple radiological tests, thus improving diagnostic and cost efficiency, improving patient compliance and ultimately reducing radiation dose [ 1 ]. Multidetector CT of the small bowel: Intramural haemorrhage, vasculitis, ischaemia, hypoalbuminaemia and angio-oedema. Improve bowel distension by active supervision and encouragement of oral contrast intake Carefully navigate the lumen Use a multiplanar review Differential contrast enhancement of the bowel is a cardinal sign The jejunum enhances more than the ileum Collapsed bowel loops and focal small bowel spasm can mimic pathology the; look for associated changes. Is it a real problem in routine practice?

Supine single phase images acquired at 50 s post-intravenous contrast administration. Table 6 Affected layer of the small bowel. Target appearance with stratification of the layers of the small bowel wall mural stratification is generally found with benign conditions—for example, vasculitis, Crohn’s disease, venous thrombosis with associated bowel oedema or ischaemia and intramural haemorrhage. Water—methylcellulose solution, polyethylene glycol, commercially available low-density barium, 0.

Akin to CT colonography, optimising luminal distension will facilitate enterogarphy and efficient luminal navigation, enabling accurate detection and characterisation of abnormalities. In intestinal tuberculosis, for example, the lymph nodes have a central low attenuation, while in lymphoma and Crohn’s disease the nodes are usually of soft tissue density. It seems that imaging examinations have a higher acceptance than endoscopic modalities regardless of small bowel examination or colon disease screening.

Clinical impact of multidetector computed tomography before double-balloon enteroscopy for obscure gastrointestinal bleeding. CT enterography is more efficient, and probably preferred by patients owing to the absence of a nasoduodenal tube and shorter examination timesbut further studies will help compare differences in examination quality, patient experience and diagnostic impact.

CT enterography as a diagnostic tool in evaluating small bowel disorders: Then, assuming no contraindication, 20 mg Buscopan Boehringer Ingelheim Ltd, Bracknell, UK is administered intravenously immediately prior to scanning to decrease small bowel peristalsis.

Griffin N, Westerland O. Use of positive oral contrast should particularly be avoided in obscure gastrointestinal bleeding because the contrast can obscure the bleeding site.

Computed tomography enterography CTE and double-balloon enteroscopy DBE are widely used in diagnosis of small bowel diseases.

Meckel’s diverticulum with ectopic gastric mucosa in a year-old male with gastrointestinal bleeding. Maximal small bowel enhancement on MDCT has been reported by Schindera et al [ 17 ] to be 50 s after administration of intravenous contrast or 14 s after aortic peak enhancement.

However, capsule endoscopy is unable to assess the extramucosal manifestations or complications of disorders affecting the small bowel; for example, small bowel Crohn’s disease is well recognised as a disease of both mucosa and mesentery, with variable involvement of both components.

Patients were asked to drink 2, mL 2. Variety of shapes; soft tissue mass with heterogeneous attenuation; duodenal ones can be papillary or polypoid; more distal ones are likely to be annular.

CT enterography: review of technique and practical tips

Mural stratification describes the visible layers of the inflamed small bowel wall demonstrated following administration of intravenous contrast in the enteric phase. In conditions where there is thickening of the submucosa, the equivalent barium follow-through appearance is classically described as stacked coin- or picket fence-like.

The six selectable options were discomfort of the bowel preparation, ingesting large amount of mannitol, radiation exposure, prolonged time entfrography of the test, high cost, and slow recovery of bowel function after the exam.

CT enterography: review of technique and practical tips

CT enterography allows simultaneous assessment of the small and large bowel, and extraluminal disease. Various studies have investigated the optimal volume of oral contrast that should be ingested, balancing the need for good distension with patient compliance and side effect profile.

The site, degree and symmetry of mural thickening can also help in the characterisation of small bowel pathology. Multidetector CT enterography versus double-balloon enteroscopy: If utilised in higher-risk groups, consider reducing the volume of intravenous contrast, ensure patients are well hydrated before the examination and monitor renal function closely afterwards.

Focal small bowel spasm is frequently encountered, despite the use of Buscopan, and can mimic short strictures.
