RATIONALE AND OBJECTIVES: The purpose of this study was to examine whether @entity1 with @entity0 history only can benefit from screening breast magnetic resonance imaging (MRI) by comparing them to @entity1 with both a personal and a family history of @entity0 . MATERIALS AND METHODS: With Institutional Review Board approval and waiver of informed consent, a retrospective review was conducted to determine @entity1 previously diagnosed with @entity0 undergoing screening MRI. From December 2003 to October 31, 2014, a total of 4436 screening MRI examinations were performed; 381 examinations were performed in 131 @entity1 with a personal history (PH) of @entity0 . This cohort was evaluated further and revealed 146 examinations in 52 @entity1 with PH only, and 235 examinations in 79 @entity1 with personal history and family history (PHFH). Fisher's exact test was used to compare the distribution between the groups. RESULTS: Total number of MRI examinations performed per @entity1 ranged from 1 to 10, with an average of 2.9 in the PHFH group and 2.8 in the PH only group. @entity1 age at time of original diagnosis was significantly different between the groups (P   =   0.0391). There were 74 (19.4%) suspicious MRI findings: 27 in the PH only group and 47 in the PHFH group. Fifty-two had needle biopsy tissue sampling performed; three additional lesions were sampled at excision. Malignancy was detected in 27.3%: 53.3% in the PHFH group and 46.7% in the PH only group (P   =   0.7963). There was no significant difference when the pathology between the PH only group and the PHFH group was compared (P   =   0.5692). Of those diagnosed with @entity5 , average time between diagnoses was 6.9 years for the PHFH group and 7.1 for the PH only group (range 2-16). CONCLUSIONS: @entity1 with a PH only are at a similar risk level as those with additional family history for the development of a subsequent @entity0 and therefore benefit from screening breast MRI, as a similar rate of @entity5 detection was found in both groups.
