To test accuracy and reproducibility of breast US with MR volume navigation and fusion imaging (VNav) as reference.
Methods and Materials
Five healthy female volunteers (45±12 years, range 33-65) 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 after positioning three vitamin E capsules over a corresponding surgical skin marker. Later than, each subject underwent unilateral US exam (LOGIQ E9, GE Healthcare) with high-resolution linear probe using MR volume coregistration with VNav software by means of an electromagnetic transmitter close to...
In all subjects VNav was obtained. Time to obtain VNav was 10±2 and 9±4 minutes (p=0.642). A total of one hundred point-to-probe distances were measured. For each radiologist, point-to-probe distance mean and SD were 0.42±0.32 cm, 0.58±0.41 cm (p=0.16) and 0.50±0.32 cm and 0.56±0.52 cm (p=0.92), respectively.
Breast US with VNav can be obtained with acceptable level of accuracy and elevated values of intra- and interobserver agreement.
