摘要: A localization grid for use with magnetic resonance (MR)-guided biopsies was designed and evaluated. First, the signal intensities of various concentrations Gd-DTPA in polyethylene tubes different sizes at pulse sequences were The optimal intensity on all obtained a concentration 500 microM. then made 5-mm-diameter filled 500-microM Gd-DTPA. has provided excellent MR-guided biopsy fluid aspiration.
