PDFAbstract
Objective To analyze the clinical value of MRI multi-sequence scan in the diagnosis of breast cancer. Methods The clinical data of 150 patients with breast cancer examined by MRI in the hospital from January 2013 to April 2017 were collected. All the patients underwent 1.5T conventional MRI scan, dynamic contrast-enhanced imaging (DCE) and diffusion weighted imaging (DWI) examination. The clinical value of MRI multi-sequence scan in the diagnosis of breast cancer was analyzed. Results The diagnostic efficiency of DWI sequence in different MRI sequences was the highest, and the sensitivity, specificity and accuracy were 93.40%, 75.00% and 88.00%, respectively, followed by DCE scan, and the sensitivity, specificity and accuracy were 86.79%, 61.36% and 79.33%, respectively. The synthetic value of MRI plain scan was the lowest, and the sensitivity, specificity and accuracy were 73.58%, 50.00% and 66.67%, respectively. Conclusion The comprehensive value of MRI DWI sequence is the highest in the diagnosis of breast cancer, followed by MRI dynamic contrast- enhanced scan.
