摘要: OBJECTIVE. The purpose of our study was to test the accuracy sonographically guided biopsies in a phantom structures not visible on sonography but shown MRI by using commercially available systems with image fusion software.MATERIALS AND METHODS. A previously recorded examination from custom-made loaded into system. contained spheres that were invisible and red dye. dye biopsy if it successful. images coregistered both MRI, taken. procedure continued until successful, number needle passes time spent registered.RESULTS. total 130 targets hit. Ten minutes used for loading data set coregistration; 94 (72.3%) successful at first pass. median obtained was...
