Feasibility of Proton Chemical Shift Imaging with a Stereotactic Headframe

Purpose： To prove feasibility of proton chemical shift. imaging (1H CSI) during stereotactic procedure, authors peformed 1H CSI in combination with a stereotactic headframe and selected targets according to local metabolic information, evaluated the pathologic results Materials and methods： The 1H CSI directed stereotactic biopsy was performed in five patients. 1H CSI was performed before conventional stereotactic MRI with gadolinium enhancement for stereotactic coordinates. The metabolite images expressed as integral ratios, Cho/Cr and Lac/Cr, were displayed in different colors. The stereotactic target coordinates were correlated with the coordinates from the 1H CSI images.
