Abstract: Objective To explore the application of parallel acquisition technology in GE breast dynamic enhancement (VIBRANT) technology based on 3.0TMR platform. Methods 70 patients with breast cancer who underwent MR dynamic contrast-enhanced scanning from January 2020 to December 2020 in the Affiliated Cancer Hospital of Shantou University Medical College were selected prospectively, all of whom were female. All patients were examined by dynamic enhanced scanning with parallel acquisition technology and dynamic enhanced scanning without parallel acquisition technology. The scanning time, spatial resolution, signal-to-noise ratio and contrast of the two methods were calculated and compared statistically. The scan time, image quality, diagnostic performance sensitivity, specificity, and accuracy of the two methods of dynamic contrast-enhanced MR with and without the ARC technique were compared. Results In VIBRANT breast dynamic enhancement scan, the scanning time with parallel acquisition technology technology was significantly shorter than that without parallel acquisition technology technology (P<0.05). The spatial resolution of the two inspection methods was the same. There was no significant difference in signal-to-noise ratio and contrast between the two methods (P>0.05). Taking pathological diagnosis as the gold standard, there was no significant difference in the sensitivity, specificity, accuracy and negative predictive value of dynamic contrast-enhanced MRI between the two methods (P>0.05). Two methods were highly consistent with pathological diagnosis of breast cancer. Conclusion VIBRANT dynamic enhanced breast scan sequence based on parallel acquisition technology has good diagnostic sensitivity, specificity and accuracy, and does not affect its diagnostic efficiency on the premise of significantly shortening the scanning time.
