OBJECTIVES: To investigate whether background parenchymal enhancement (BPE) and @entity0 would correlate searching for any significant difference of BPE pattern distribution in case of benign or @entity5 . METHODS: 386 @entity1 , including 180 pre-menopausal (group 1) and 208 post-menopausal (group 2), underwent MR examination. Two radiologists evaluated MR images classifying normal BPE as minimal, mild, moderate or marked. The two groups of @entity1 were subdivided into 3 categories based on MRI findings (negative, benign and @entity5 ). The distribution of BPE patterns within the two groups and within the three MR categories was calculated. The   (2) test was used to evaluate BPE type distribution in the three @entity1 categories and any statistically significant correlation of BPE with lesion type was calculated. The Student t test was applied to search for any statistically significant difference between BPE type rates in group 1 and 2. RESULTS: The   (2) test demonstrated a statistically significant difference in the distribution of BPE types in negative @entity1 and benign lesions as compared with malignant ones (p<0.05). A significant higher prevalence of moderate and marked BPE was found among @entity5 (group 1: 32% and 42%, respectively; group 2: 31% and 46%, respectively) while a predominance of minimal and mild BPE among negative @entity1 (group 1: 60% and 36%, respectively; group 2: 68% and 32%, respectively) and benign lesions (group 1: 54% and 38%, respectively; group 2: 75% and 17%, respectively) was found. The Student t test did not show a statistically significant difference between BPE type rates in group 1 and 2 (p>0.05). CONCLUSION: Normal BPE could correlate with the risk of @entity0 being such BPE patterns as moderate and marked associated with @entity1 with @entity5 in both pre and post-menopausal @entity1 .
