Value of MR imaging in clinical evaluation of breast lesions

Abstract

MR imaging might be of value as an additive method to TD by increasing the sensitivity, but at the cost of decreasing specificity. Patients with mammographically dense parenchyma might have more benefit of the additive value, as the decrease in specificity in these patients was less pronounced in our study.

Dynamic MR Imaging Of The Breast. Analysis of kinetic and morphologic diagnostic criteria

“…Patients: This study was carried out on a consecutive cohort of 93 female patients with 114 lesions undergoing preoperative dynamic MR according to a prospective protocol (18). Five lesions (a 2‐mm in situ lobular cancer, and 4 in situ ductal carcinomas with a diameter of 10–30 mm), which were not visible on the MR images, were excluded from further analysis.…”

Comparison of 99mTc-Sestamibi Scintimammography and Dynamic MR Imaging as Adjuncts to Mammography in the Diagnosis of Breast Cancer

“…Criteria for patient selection and the order of diagnostic procedures have been described previously (9), and are presented in a flow chart (Fig. 1).…”

Quantitative diffusion weighted imaging for differentiation of benign and malignant breast lesions: The influence of the choice of b‐values

“…MRI of the breast has obtained a prominent role in clinical practice because of its high sensitivity for detecting invasive breast tumors (1)(2)(3). However, the specificity of DCE MRI of the breast, is substantially lower.…”

“…However, the specificity of DCE MRI of the breast, is substantially lower. It was shown to reach approximately 70% (1)(2)(3). Many different strategies have been proposed to increase the specificity such as calculating pharmacokinetic contrast parameters (4), T2*-weighted perfusion imaging (5) and MR spectroscopy (5).…”
