Objective: To evaluate the application of multivane technique at 3.0 T MRI in female pelvis examination in reducing artifacts and improving image quality. Methods: A total of 49 female patients were collected between December 2016 and April 2018 from Zhongda Hospital Affiliated to Southeast University, which were examined with sagittal T(2)-weighted TSE, T(2) weighted -MV and T(2) weighted-SShTSE with fat suppression on a 3.0 T scanner.Three radiologists assessed the images for the presence of artifacts and overall image quality using a five-point scale after Cronbach's Alpha repeatability measurement of the three doctors. Results: The Cronbach's Alpha of the three doctors was 0.950, 0.973, 0.985, respectively.Both MV and SShTSE groups got higher points than TSE group.In the level of anatomic detail, the differences was statistically significant(all P<0.05). Although there was no significant difference between MV and SShTSE group in the score of doctor 1 (P=0.126), but had significant differences in the score of doctor 2 (P=0.022)and doctor 3(P=0.005). In assessing the images for the presence of artifacts, both MV and SShTSE groups got higher points than TSE group, while SShTSE group got higher points than MV group, and the differences were statistically significant (all P<0.05). In assessing the overall image quality, both MV and SShTSE groups got higher points than TSE group, while MV group got higher points than SShTSE group, and the differences were statistically significant (all P<0.05). Conclusion: Imagings of the anatomic detail are improved and the artifacts associated with bowel or respiratory motion are reduced with the MV technique.MV technique is important in providing an accurate diagnosis compared with TSE and SShTSE.
