Insights

Multi-detector row helical CT (MDCT) accurately detects and localizes acute gastrointestinal (GI) and intraperitoneal bleeding. This imaging technique is fast and reliable for identifying bleeding sources in emergency situations.

Area of Science:

  • Radiology
  • Gastroenterology
  • Emergency Medicine

Background:

  • Acute gastrointestinal (GI) and intraperitoneal bleeding present diagnostic challenges.
  • Timely and accurate localization of bleeding is crucial for effective patient management.

Purpose of the Study:

  • To assess the diagnostic accuracy of multi-detector row helical CT (MDCT) in identifying acute upper and lower GI hemorrhage.
  • To evaluate MDCT's effectiveness in detecting intraperitoneal bleeding sources.

Main Methods:

  • Thirty-six patients with clinical signs of acute bleeding underwent biphasic MDCT (16- or 40-channel).
  • MDCT findings were correlated with subsequent diagnostic or therapeutic procedures (endoscopy, angiography, surgery).

Main Results:

  • MDCT correctly identified the bleeding site in 24 of 26 patients with GI bleeding.
  • Active contrast material (CM) extravasation was visualized in 20 of these patients.
  • MDCT accurately located the bleeding source in 9 of 10 patients with intraperitoneal hemorrhage.

Conclusions:

  • MDCT provides fast and accurate localization of acute GI bleeding.
  • MDCT is a valuable tool for identifying sources of intraperitoneal hemorrhage.
  • The study confirms MDCT's efficacy in emergency bleeding scenarios.

Imaging Studies for Cardiovascular System V: CT

Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...

Imaging 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...

Upper GI Series: Barium Swallow

The Barium Swallow Study, or a Barium Esophagogram, is a diagnostic imaging method used to visualize the upper gastrointestinal (GI) tract, including the esophagus, stomach, and small intestine. It employs barium sulfate, a radiopaque contrast material, to provide clear images of the upper digestive system, helping to identify abnormalities, diseases, or structural issues.
Purpose and Procedure
Patients undergoing this procedure ingest a liquid containing barium sulfate with a chalky...
