Abstract:
Objective:To explore the value of different MRI sequences in the diagnosis of breast lesions. Methods:Using Philips Achieva 1.5T Nova Dual MRI with SENSE～ breast coil, MRI scanning was performed on 21 patients clinically suspected suffering from breast cancer. MRI sequences included T1WI/TSE,T2WI/TSE (turbo spin echo), short TI inversion recovery(STIR),diffusion weighted whole body imaging with background body signal suppression (DWIBS) and dynamic contrast-enhanced MRI scanning THRIVE. MRI findings were compared with histopathological results. Results:The detection rates of breast lesions of the five sequences were 53.85%, 65.38%, 80.77%, 88.46% and 100%. The sensitivity, specificity and accuracy of dynamic contrast-enhanced MRI scanning were 100%, 77.78%, and 92.31% respectively, which were better than other sequences in the differential diagnosis of the lesions. Conclusion:Dynamic contrast-enhanced MRI scanning could accurately show the numbers of the lesions, describe the morph and size of the lesions and provide more information for the surgeons. DWIBS and STIR could detect the breast lesions more sensitively than T1WI/TSE and T2WI/TSE sequences.
