Small Bowel Imaging

چکیده
The small bowel, affected by a host of pathologic conditions can be difficult and challenging to image because of its length and tortuous course. However the small bowel imaging is evolving. There was a time when small-bowel follow-through (SBFT) was the primary and only method of diagnosing diseases of the small bowel. In recent years, there has been availability of a variety of techniques such as ultrasound (US), contrast enhanced ultrasound (CEUS), computed tomography (CT), magnetic resonance imaging (MRI), computed tomography enteroclysis/enterography (CTEc)/ CTEg), magnetic resonance enteroclysis/enterography (MREc/MREg) and small bowel endoscopy methods including capsule endoscopy. Digital subtraction angiography (DSA) for diagnostic purposes has in the majority of indications been replaced by CT angiography (CTA) while DSA is reserved for guidance of interventional procedures. New ultrafast techniques in MRI & Magnetic resonance angiography (MRA) using IV contrast medium are able to compete with CTA1.

MDCT of small bowel tumours
Primary benign and malignant neoplasm of the small bowel are rare. Malignant tumours often present late symptoms resulting in a poor prognosis. Early detection of small bowel neoplasms is desirable but challenging for both clinicians and radiologists. Conventional double contrast enteroclysis was the method of choice in small bowel imaging but is increasingly being replaced by cross-sectional i...

3-D Modeling and Virtual Endoscopy of the Small Bowel Based on MR Imaging in Patients with Inflammatory Bowel Disease Investigative Radiology 2002;37(9):528-533
Rationale and Objectives: Small bowel MRI (Magnetic Resonance Imaging) is a new imaging modality which excellently depicts small intestine pathology in patients with inflammatory bowel disease. Virtual endoscopy based on sectional imaging is a recently introduced technique to create endoscopy like views. The aim of this study was to evaluate the feasibility of virtual small bowel endoscopy base...

The small bowel is essential to sustain alimentation and small bowel Crohn's disease (CD) may severely limit its function. Small bowel imaging is a crucial element in diagnosing small bowel CD, and treatment control with imaging is increasingly used to optimize the patients outcome. Thereby, capsule endoscopy, Balloon-assisted enteroscopy, and Magnetic resonance imaging have become key players ...
