|Value of second look breast US with and without volume navigation and fusion imaging using contrast-enhanced MR as reference|
Methods and Materials
Twenty-four patients (52±18 years, range 33-77) with additional lesions at conventional MR underwent bilateral contrast-enhanced (0.1 mmol/Kgbw Gd- BOPTA, Bracco Diagnostics) breast MR in supine position (1.5T, Achieva, Philips Healthcare) using T1-weighted high resolution isotropic examination volume and spectral attenuated inversion recovery fat suppression with body coil. Three fiducial, pills of vitamin E on the corresponding skin markers were used. US and MR coregistration was obtained by means of a magnetic transmitter positioned close to the patient and two small magnetic receivers positioned on a linear probe’s bracket (LOGIQ E9, GE Healthcare). The same radiologist performed first second look US without and then with VNav. Images were reviewed by consensus by two experienced radiologist. Pathologic examination was the standard of reference. McNemar test was used.
