In vivo MR spectroscopic imaging with P-31. Work in progress

Area of Science:

• Neuroimaging
• Biophysics
• Medical Diagnostics

Background:

• Stroke induces metabolic alterations in brain tissue.
• Non-invasive monitoring of in vivo metabolism is crucial for understanding neurological conditions.
• Phosphorus magnetic resonance spectroscopy (31P MRS) offers insights into cellular energy metabolism.

Purpose of the Study:

• To investigate the utility of in vivo phosphorus magnetic resonance imaging (31P MRI) for detecting stroke-induced metabolic changes in the cat brain.
• To assess the feasibility of spatially resolved 31P spectroscopy for monitoring tissue metabolism.
• To report preliminary findings of in vivo 31P MRI in humans.

Main Methods:

• Application of magnetic resonance imaging (MRI) techniques.
• In vivo spectroscopic analysis of spatially resolved phosphorus (31P) spectra.
• Acquisition of two-dimensional images of phosphorus-containing compounds.
• Generation of spectra from spatially localized points within the brain.

Main Results:

• Demonstrated the ability to monitor tissue metabolism using 31P MRI.
• Successfully obtained spatially resolved phosphorus spectra in the cat brain.
• Detected metabolic changes associated with stroke in the feline brain.
• Reported preliminary in vivo 31P MRI results in humans.

Conclusions:

• In vivo 31P MRI is a viable technique for detecting metabolic changes in the brain, including those associated with stroke.
• Spatially resolved 31P spectroscopy enables non-invasive monitoring of tissue metabolism.
• The findings support the potential clinical application of 31P MRI for neurological diagnostics.
