Preliminary in vivo validation of a dedicated breast MRI and sonographic coregistration imaging system.
OBJECTIVE
Sonographic correlation of breast MRI findings is often challenging. We present a preliminary in vivo feasibility study evaluating the degree of error of a new MRI-sonography coregistration system for showing MRI and sonographically visible breast lesions.


CONCLUSIONS
In 10 patients with 13 lesions, the system was found to be an accurate means for targeting sonography to MRI of the same breast lesions.
