Abstract
A localization grid for use with magnetic resonance (MR)-guided biopsies was designed and evaluated. First, the signal intensities of various concentrations of Gd-DTPA in polyethylene tubes of different sizes and at various pulse sequences were evaluated. The optimal signal intensity on all pulse sequences was obtained with a concentration of 500 .mu.M. A grid was then made with 5-mm-diameter polyethylene tubes filled with 500-.mu.M Gd-DTPA. The grid has provided excellent localization for MR-guided biopsy and fluid aspiration.This publication has 2 references indexed in Scilit:
