Intratumoral Intensity in T2-weighted MRI and the Association With Histological and Molecular Prognostic Factors in Women With Invasive Breast Cancer.

Objective: To compare the intratumoral T2 signal intensity on MRI and histopathological and molecular expression of biomarkers of aggressiveness (histological grade, hormonal status, HER2, and Ki-67).

Methods: This retrospective study included all women with invasive breast cancer undergoing MRI from January 2014 to October 2016. The intratumoral T2 signal as interpreted at consensus by two radiologists was compared to histopathological and molecular prognostic factors from the surgical specimen.

Indications for breast magnetic resonance imaging at a referral center for the diagnosis and treatment of breast cancer in Brazil.

Objective: To describe the indications for breast magnetic resonance imaging (MRI) at a referral center for breast cancer in Brazil.

Materials And Methods: This was a retrospective study in which we reviewed the clinical records, including physician requests and patient questionnaires, of women who underwent breast MRI between 2014 and 2018 at a referral center for the diagnosis and treatment of breast cancer in the city of Belo Horizonte, Brazil.

Results: The most common indication for breast MRI was as a complement to mammography/ultrasonography (in 43.
