Abstract

Objective

The study objective was to detect abnormalities and identify relationships between brain metabolic ratios determined by proton magnetic resonance spectroscopic imaging (1H-MRSI) and neuropsychological (NP) function in cancer patients at risk for neurotoxicity.

Methods

Thirty-two patients received 1H-MRSI using a multi-slice, multi-voxel technique on a 1.5T magnet. Cho/NAA, NAA/Cr, and Cho/Cr ratios were identified in seven pre-determined sites without tumor involvement. A battery of age-appropriate NP tests was administered within 7 days of imaging. Relationships were examined between test scores and metabolite ratios.

Conclusions

This study identifies relationships between brain metabolite ratios and cognitive functioning in cancer patients. 1H-MRSI may be useful in early detection of neurotoxic effects, but prospective longitudinal studies in a homogeneous population are recommended to determine the prognostic value.
