Summary
Recent advances in multi-detector row CT (MDCT) scanners and neutral oral contrast agents improve small bowel imaging. A systematic pattern approach aids in diagnosing abnormal small bowel loops found on MDCT scans.
Area of Science:
- Radiology
- Gastroenterology
- Medical Imaging
Background:
- Small bowel imaging has advanced significantly.
- Multi-detector row CT (MDCT) scanners acquire isotropic data.
- Neutral oral contrast agents enhance small bowel distention.
Purpose of the Study:
- To review advances in small bowel imaging.
- To demonstrate a systematic pattern approach for diagnosing small bowel pathologies on MDCT.
Main Methods:
- Review of recent literature on small bowel imaging.
- Application of a pattern-based diagnostic strategy for MDCT findings.
Main Results:
- MDCT with isotropic data acquisition offers detailed small bowel visualization.
- Neutral oral contrast agents improve bowel distention and lesion conspicuity.
- A systematic approach effectively narrows the differential diagnosis.
Conclusions:
- Advanced MDCT techniques facilitate the imaging of diverse small bowel pathologies.
- A pattern-based approach is crucial for accurate diagnosis of abnormal small bowel loops on MDCT.

01:26Imaging Studies III: Gastrointestinal Motility Studies and Virtual Colonoscopy
This lesson explores three gastrointestinal imaging techniques: radionuclide testing, colonic transit studies, and virtual colonoscopy.
Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
In gastric emptying studies, a meal's liquid and solid...

01:25Assessment of the Rectum and Anus
Evaluating the rectum and anus plays a crucial role in conducting a thorough physical examination of the gastrointestinal system. Although it may be uncomfortable and often embarrassing for the patient, it holds immense diagnostic value, particularly in detecting gastrointestinal diseases and abnormalities. This guide will explain how to perform this assessment using inspection and palpation methods.

01:25Assessment of the Abdomen I: Inspection and Auscultation
Introduction
The abdominal examination is a cornerstone of clinical medicine, serving as a critical tool in diagnosing various gastrointestinal (GI) diseases. It involves a systematic approach that includes inspection and auscultation, each with distinct yet complementary roles in assessing the abdomen. This article will delve into these two primary methods healthcare professionals use to examine the abdomen.

01:23Lower GI Series: Barium Enema
A Barium Enema, or a lower GI series, is a specialized radiographic examination designed to visualize the lower gastrointestinal tract, specifically the colon and rectum. This procedure is instrumental in diagnosing various conditions such as colorectal cancer, polyps, diverticulosis, and inflammatory bowel disease.
Procedure Details
The examination begins by inserting a lubricated rectal tube into the patient's rectum to administer a radiopaque barium solution. The barium flow is carefully...
