Differences in morphological features and minimum apparent diffusion coefficient values among XXXX subtypes using 3-tesla MRI.

@entity1 @entity0 @entity5 @entity189 @entity513 @entity549 @entity1722
PURPOSE: To compare the morphology and minimum apparent diffusion coefficient (ADC) values among @entity0 subtypes. METHODS: Ninety-three @entity1 , who underwent breast MRI and collectively had 98 pathologically proven invasive @entity189 , were enrolled. Morphology was evaluated according to BIRADS-MRI. Minimum ADC was measured. Morphology and minimum ADC were compared among subtypes. Multivariate logistic regression analyses were used to identify the characteristics associated with different subtypes. RESULTS: Oval/round shape was significantly associated with @entity5 ( @entity549 vs. @entity549 : 90.9% vs. 45.2%; p=0.0123). Rim enhancement was significantly less frequent in Luminal A (Luminal A vs. non-Luminal A: 34.2% vs. 76.1%; p=0.0003). The minimum ADC of Luminal A was significantly higher than that of Luminal B ( @entity1722 -negative) (834 vs. 748*10(-6)mm(2)/s; p<0.025). The minimum ADC of the @entity549 -special type was significantly higher than that of @entity513 (997 vs. 702*10(-6)mm(2)/s; p<0.025). On the multivariate analysis comparing the characteristics associated with Luminal A vs. Luminal B ( @entity1722 -negative), the internal enhancement characteristics of the mass and minimum ADC were significant factors. CONCLUSION: Morphology and minimum ADC would be useful in distinguishing @entity0 subtypes.
