ABSTRACT
Second look US evaluation is frequently performed for assessing incidentally discovered enhancing lesions seen on MRI. However, the success of the examination depends on the experience and technique of the operator. Sonographic identification of an MRI incidentally detected lesion is difficult because the patient's body is positioned differently during sonography than it is during MRI. Fusion imaging of MRI and US has recently been developed, for which a position tracking system is coordinated with a magnetic sensor. This system synchronizes an ultrasound image and the MR image with multi-planar reconstruction (MPR) of the same area in real time. The purpose of this study was to evaluate the usefulness of fusion imaging of MR and US for evaluating breast lesions.
