[Diagnostic imaging of the small bowel]

Area of Science:

• Radiology and Medical Imaging
• Gastroenterology

Background:

• Small bowel imaging is crucial for diagnosing various gastrointestinal conditions.
• Conventional techniques like small bowel follow-through have limitations in visualizing the entire small intestine effectively.

Purpose of the Study:

• To describe and evaluate different imaging techniques for small bowel examination.
• To compare conventional methods with advanced imaging modalities like computed tomography and magnetic resonance imaging.

Main Methods:

• Review of technical requirements for conventional small bowel follow-through studies.
• Evaluation of different enteroclysis types, focusing on biphasic enteroclysis.
• Assessment of modern imaging techniques: computed tomography (CT) and magnetic resonance imaging (MRI) enteroclysis.

Main Results:

• Biphasic enteroclysis offers advantages over conventional small bowel follow-through.
• CT and MRI enteroclysis excel at resolving superimposed intestinal loops and evaluating the intestinal wall and extraluminal pathology.
• Modern techniques do not surpass conventional methods in detailing the intestinal mucosa.

Conclusions:

• Accurate indications, meticulous examination, and careful interpretation are vital for small bowel studies.
• Advanced imaging techniques like CT and MRI enteroclysis are valuable adjuncts for complex small bowel evaluations.
• The choice of imaging modality depends on the specific diagnostic question and clinical scenario.
