31P magnetic resonance spectroscopy of mesenteric ischemia
Magnetic Resonance in Medicine
|January 1, 1987
Abstract:
31P magnetic resonance spectroscopy (MRS) was performed in vivo on normal and ischemic rat intestine. Within 3 min after induction of ischemia, there is a dramatic fall in adenosine triphosphate (ATP) and rise in inorganic phosphate (Pi). Our results suggest that MRS may prove useful in the early detection of mesenteric ischemia.
Insights
31P magnetic resonance spectroscopy detected rapid changes in intestinal energy metabolism during ischemia. This technique shows promise for the early diagnosis of mesenteric ischemia.
Area of Science:
- Biomedical Engineering
- Gastroenterology
- Medical Imaging
Background:
- Intestinal ischemia is a critical condition requiring early detection.
- Current diagnostic methods for mesenteric ischemia may have limitations in speed and sensitivity.
Purpose of the Study:
- To investigate the utility of 31P magnetic resonance spectroscopy (MRS) for in vivo assessment of intestinal energy metabolism during ischemia.
- To determine if MRS can detect early biochemical changes indicative of mesenteric ischemia.
Main Methods:
- 31P magnetic resonance spectroscopy (MRS) was employed to analyze the metabolic state of rat intestine.
- In vivo studies were conducted on both normal and experimentally induced ischemic rat intestine models.
Main Results:
- A rapid and significant decrease in adenosine triphosphate (ATP) levels was observed within 3 minutes of ischemia induction.
- Concurrently, a marked increase in inorganic phosphate (Pi) was detected in the ischemic intestinal tissue.
Conclusions:
- 31P magnetic resonance spectroscopy can detect rapid alterations in high-energy phosphate metabolites during intestinal ischemia.
- MRS holds potential as a valuable tool for the early, non-invasive detection of mesenteric ischemia.
