Cellular Lactate Spectroscopy Using 1.5 Tesla Clinical Apparatus

Area of Science:

• Biochemistry
• Cell Biology
• Medical Imaging

Background:

• Cellular lactate is a crucial metabolite linked to anaerobic glycolysis and cellular energy metabolism.
• Lactate presence is observed in neoplasms and associated with anaerobic glucose metabolism, mitochondrial dysfunction, and inflammation.

Purpose of the Study:

• To detect cellular lactate in cancer cell cultures using proton magnetic resonance spectroscopy (¹H MRS).
• To evaluate the feasibility of using a clinical 1.5 Tesla MRI system for detecting small molecules like lactate.

Main Methods:

• Utilized proton magnetic resonance spectroscopy (¹H MRS) on cancer cell cultures.
• Employed a 1.5 Tesla clinical MRI apparatus (MR OPTIMA 360) with a specific protocol and algorithm.
• Identified cellular lactate and other selected metabolites.

Main Results:

• Successfully detected cellular lactate in cancer cell cultures.
• Demonstrated the capability of a medium-field clinical MRI system to identify small molecules.
• Confirmed the utility of ¹H MRS with clinical MR apparatus for metabolite detection.

Conclusions:

• Proton magnetic resonance spectroscopy (¹H MRS) on a clinical 1.5 Tesla MRI system is effective for detecting cellular lactate.
• This method provides a valuable tool for clinical analysis of metabolic states in cancer.
• Clinical MR instruments can be utilized for the detection of small molecules like lactate.
