Dimensions of the Breast Lesion: Imaging Results vs Pathological Results
Abstract:
Introduction: To verify the correlation between the measurement of the dimensions of the same tumor in MGM, US and MRI, and the dimensions of the tumor referred to in the anatomopathological report of the surgical specimen.
Materials and methods: A retrospective study was carried out on 56 women diagnosed with breast cancer, between January 2021 and November 2022, at the CHUA Radiology Service, at the Portimão E.P.E. where the size of the main tumor was evaluated by MGM, US and breast MRI and later compared with the anatomo pathological examination.
Results: It was found that at the level of MGM, US and MRI an overestimation of 34/56 (60.7%), 18/56 (32%) and 31/56 (55%) respectively, and an underestimation of 18 /56 (32%), 34/56 (60.7%) and 19/56 (33%), re spectively.
Conclusion: It was concluded that there were no significant differences in the size of the tumors measured in MGM and MRI when compared with the pathological anatomy, nor based on the histological type or breast density, demonstrating that the factors do not influence the accuracy of the measurement. MRI was the tech nique that obtained the best correlation with size in the anatomopathological examination.
