[Bowel imaging: a reassessment. Part 2: CT and MRI]

Area of Science:

• Medical Imaging
• Gastroenterology
• Radiology

Background:

• The first part of this review covered conventional X-ray and ultrasonography for bowel imaging.
• Advanced imaging modalities are crucial for diagnosing complex bowel disorders.

Purpose of the Study:

• To review the diagnostic features of computed tomography (CT) and magnetic resonance imaging (MRI) for bowel disorders.
• To compare CT and MRI with other techniques like capsule endoscopy.

Main Methods:

• Discussion of computed tomography (CT) features.
• Review of magnetic resonance imaging (MRI) applications, including virtual colonography.
• Inclusion of positron emission tomography-computed tomography (PET-CT) in bowel disorder diagnosis.

Main Results:

• Detailed presentation of diagnostic features for CT and MRI in bowel imaging.
• Evaluation of indications and performance of advanced imaging techniques.
• Comparative analysis of diagnostic impact against methods like capsule endoscopy.

Conclusions:

• CT and MRI offer significant diagnostic capabilities for various bowel disorders.
• These advanced techniques provide valuable insights beyond conventional methods.
• The choice of imaging modality depends on the specific clinical indication and diagnostic goals.
