Summary

CT enteroclysis (CTE) is an advanced imaging technique for small bowel disorders. It excels in diagnosing Crohn's disease, tumors, and obstructions, offering superior visualization of mural abnormalities and complications.

Area of Science:

  • Radiology
  • Gastroenterology
  • Medical Imaging

Background:

  • CT enteroclysis (CTE) has advanced with spiral and multidetector CT technology.
  • It is a well-defined imaging modality for small bowel disorders.

Purpose of the Study:

  • To evaluate the diagnostic value of CT enteroclysis for small bowel disorders.
  • To highlight its role in specific conditions like Crohn's disease and tumors.

Main Methods:

  • Administration of 2L enteral contrast via nasojejunal catheter for luminal distension.
  • CT acquisition focused on small bowel loops with thin axial slices and multiplanar reconstructions.
  • Image analysis performed in cine-mode on workstations.

Main Results:

  • CTE is valuable for intermediate/advanced Crohn's disease, including extraintestinal complications.
  • It is the preferred modality for small bowel tumor localization and characterization.
  • CTE effectively analyzes the cause and degree of low-grade small bowel obstruction.

Conclusions:

  • CTE is a valuable tool for specific small bowel questions, particularly in Crohn's disease and tumors.
  • Its limitations include assessment of motility disorders and superficial mucosal lesions.
  • CTE holds a defined place in modern small bowel imaging diagnostics.
