Abstract
ObjectiveThe purpose of our study was to evaluate the clinical utility of virtual navigation for magnetic resonance imaging (MRI)-detected incidental breast lesions.
MethodsBetween June 2016 and December 2018, 21 consecutive patients with 22 BI-RADS category 4 or above lesions that were detected on MRI but occult on second-look ultrasound (US) were enrolled in the study. All suspicious lesions were localized by using US/MRI fusion virtual navigation, and then underwent US-guided biopsy or surgical excision. The detection rate was calculated by comparing pre-/post-operation MRI and pathological results. The MRI features and pathological types of these lesions were analyzed.
ResultsA total of 20 lesions were successfully localized using virtual navigation and underwent US-guided biopsy or localization, and the detection rate of virtual navigation was 91%. Eighteen (90%) lesions were proved to be benign lesions, and two (10%) proved to be malignant lesions by pathology. Of the 22 MRI-detected lesions, 20 (91%) manifested as non-mass enhancements and only two (9%) were masses.
ConclusionReal-time US/MRI fusion virtual navigation can be an effective method for the evaluation of MRI-detected lesions that are not visible on US.
