Computed tomography of miscellaneous regional and diffuse small bowel disorders

Area of Science:

• Radiology
• Gastroenterology
• Abdominal Imaging

Background:

• Small bowel disorders present a wide spectrum of conditions.
• Computed tomography (CT) is a key imaging modality for evaluating the small bowel.
• Accurate interpretation of CT findings is essential for diagnosis and management.

Purpose of the Study:

• To review computed tomography (CT) findings in miscellaneous regional and diffuse small bowel disorders.
• To discuss CT technique and potential pitfalls in small bowel imaging.
• To provide clues for narrowing the differential diagnosis of small bowel conditions.

Main Methods:

• Review of imaging literature concerning common and less common small bowel entities.
• Discussion of representative CT images for various small bowel disorders.
• Emphasis on the importance of correlating CT findings with clinical information.

Main Results:

• CT findings for many small bowel disorders can be nonspecific.
• Specific CT appearances are noted in selected conditions.
• Correlation with clinical history, physical examination, and laboratory results is critical for accurate diagnosis.

Conclusions:

• Computed tomography (CT) is valuable for diagnosing small bowel disorders.
• Understanding CT technique and potential pitfalls improves diagnostic accuracy.
• A comprehensive approach integrating imaging and clinical data is essential for effective small bowel disorder evaluation.
