Biomagnetic Signals of Intestinal Ischemia

The lack of blood flow to the small intestine causes mesenteric ischemia. Using a Superconducting QUantum Interference Device (SQUID) which measures the magnetic field of the small intestine, we are hoping to identify abnormalities without surgical intervention.

Condition Phase
Phase 1

Study Type: Observational
Study Design: Observational Model: Case Control
Time Perspective: Cross-Sectional
Official Title: Biomagnetic Signals of Intestinal Ischemia II

Further study details as provided by University of South Alabama:

Primary Outcome Measures:
  • To observe a difference in the magnetic activity between normal and diseased smooth muscle [ Time Frame: 2011 ]

Enrollment: 60
Study Start Date: January 2000
Study Completion Date: January 2013
Primary Completion Date: January 2013 (Final data collection date for primary outcome measure)
Good blood flow
Group with normal blood flow to small intestine
Poor blood flow
Group with partial ischemia to small intestine

Detailed Description:
The electrical activity of the small intestine may contain important information that will help us diagnose gastrointestinal diseases. The major impediment to reducing mortality of mesenteric ischemia is the lack of a noninvasive diagnostic test that identifies the syndrome before extensive necrosis occurs. Mesenteric ischemia is caused by the lack of blood flow to the intestine. The Superconducting QUantum Interference Device (SQUID) measures the magnetic field of the intestinal smooth muscle. By comparing normal smooth muscle and that of patients with mesenteric ischemia, we hope to identify abnormal disease states without surgery.
