CT ENTEROGRAPHY THESIS

Moreover, biopsy and treatment such as hemostasis, polypectomy, and dilation are possible during DBE. MRE and trans-abdominal ultrasonography US would be alternative radiation-free imaging strategies, due to their equivalent diagnostic accuracy, better tolerance, and cost effectiveness. Axial CT enterography image showing two areas of focal small bowel spasm mimicking pathology arrows. Furthermore, collapsed bowel loops appear to enhance more than the distended loops in the same segment Figure 2 [ 2 , 18 , 19 ]. W—85 [ PubMed ] [ Google Scholar ].

In the authors’ experience, small bowel tumours are most commonly detected in patients with:. CT evaluation of small bowel neoplasms: 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. Br J Radiol ; Coronal CT enterography image showing a blind-ending gas-filled tubular structure with thickened, hyperenhancing mucosa in the left lateral margin arrows, with nodule identified by shorter arrow. CT enterography allows simultaneous assessment of the small and large bowel, and extraluminal disease. This mesenteric fat change, which manifests as abnormal loop separation on contrast examination, is easily appreciated at CT enterography Figure 4c.

Hypoalbuminaemia, infectious enteritis and occasionally ischaemia or mild Crohn’s disease. Improved visualisation of mucosal lesions compared with conventional CT. This article has been cited by other articles in PMC.

Supine single phase images acquired at 50 s post-intravenous contrast administration. Unlike MR enterography or capsule endoscopy, CT enterography utilises ionising radiation. Finally, patients completed our study, whose demographic and disease-related characteristics are summarized in Table 1.

Akin to CT colonography, optimising luminal distension will facilitate rapid and efficient luminal navigation, enabling accurate detection and characterisation of abnormalities.

In addition, mucosal visualisation is frequently incomplete at capsule endoscopy and potentially adverse complications of capsule retention or, rarely, capsule endoscope aspiration can occur [ 55 ]. Coronal CT enterography image showing a blind-ending gas-filled tubular structure with thickened, hyperenhancing mucosa in the left lateral margin arrows, with nodule identified by shorter arrow.

All authors contributed toward data analysis, drafting and critically revising the paper, and agreed to be accountable for all aspects of the work. There are several limitations to our study. CT enterography allows simultaneous assessment of the small and large bowel, and extraluminal disease.

Homogeneous hyperenhancement is commonly seen with active Crohn’s disease, and is frequently associated with increased density in the surrounding mesenteric fat. CT evaluation of nonneoplastic diseases of the small bowel: Compared with MRI enterography, the authors of this article have found that CT enterography images frequently provide greater diagnostic confidence for exclusion of both small bowel and extraluminal pathology.

However, the radiological community has not stood still. Patients were asked to drink 2, mL 2.

CT enterography: review of technique and practical tips

As noted above, multiphase CT scanning may increase the diagnostic yield in those with occult gastrointestinal bleeding, but consideration must be given to the increased radiation dose, particularly in the non-acute setting. In tehsis authors’ experience, small bowel tumours are most commonly detected in patients with:.

Segmental involvement is found with intramural haemorrhage, Crohn’s disease, lymphoma, infectious enteritis and ischaemia, particularly due to superior mesenteric artery SMA embolus or superior mesenteric vein SMV thrombosis [ 162231 – 34 ].

Recently published data on the risk of carcinogenesis in adult patients due to CT quote significantly lower-risk percentages of 0. Received 5 July Diagnosis tehsis small-bowel diseases: A systematic review and meta-analysis of preference for colonoscopy versus computerized tomographic colonography CTC showed colonoscopy was graded more uncomfortable by patients and CTC was preferred over colonoscopy in most of the studies.

The patient is then transferred to the scanner table, drinking the last cup on the table.

Neterography list of common indications for CT enterography is given in Table 7. Eur Radiol ; 9: CT enterography may show typical mucosal pattern and lymph node involvement. The indication to stop insertion was discovery of the lesion or difficulty in further advancing. Length of small bowel involvement For the purpose of differential diagnosis, the length of small bowel involvement can be divided into three: The safety of propofol infusion compared to midazolam and meperidine intravenous bolus for patients undergoing double balloon enteroscopy.
