BACKGROUND Magnetic resonance imaging(MRI)with multiparametric dynamic contrast plays a critical role in the assessment of breast *** curves are a critical parameter in determining the benign or malignant nature of *** curves of type 1 are known to represent benign masses,while dynamic curves of type 3 are known to identify malignant *** 2 dynamic curves have a sensitivity of 42.6%and specificity of 75%for malignancy *** To investigate the pathological diagnosis of lesions with type 2 dynamic *** We evaluated breast MRI examinations performed between 2020 and 2021 retrospectively and included lesions with type 2 dynamic *** included 38 lesions from 33 *** lesions were evaluated for their pathological diagnosis and morphological *** Twenty-six lesions were malignant,while twelve were *** most frequently encountered benign lesion(7/12,58.3%)was sclerosing adenosis,while the most frequently encountered malignant diagnosis was invasive ductal *** presence of a type 2 dynamic curve had a sensitivity of 40.2%and specificity of 73.4%for predicting *** combining type 2 curves and morphological features,the sensitivity and specificity were *** The high rates of malignancy detected histopathologically among patients with type 2 dynamic curves in our study are *** 2 dynamic curves can be detected in benign breast masses,especially in sclerosing adenosis *** morphological features can increase the diagnostic accuracy in cases with type 2 dynamic curves.
