Abstract:
Objective To study the value of the early enhanced morphology in three dimensional dynamic contrast-enhanced and digital subtraction MRI in diagnosing breast cancer.Methods Three dimensional dynamic contrast-enhanced and digital subtraction MRI of breast neoplasm in 46 patients(52 lesions)verified by histopathology were performed before operations.MR imaging data were analysed.On the base of early-phase enhanced rate,peak time,blood vessel morphology and time-signal intensity curve,the diagnostic values of the early enhanced morphology of lesions were evaluated.Results In the 37 malignant breast lesions,31 lesions were enhanced from the center to the margin(83.8%,31/37),14 benign breast lesions were enhanced from the margin to the center(93.3%,14/15).The special features of breast cancer in three dimensional dynamic contrast-enhanced and digital subtraction MRI were circular enhancement and the contrast medium filled from the margins to the centre of lesions in middle-later phase,its diagnostic sensitivity,specificity and accuracy were 97.3%,93.3% and 96.2% respectively.Conclusion The morphological features of three dimensional dynamic contrast-enhanced and digital subtraction MRI has obvious advantages in diagnosing breast cancer.
