Magnetic Resonance Spectroscopy of the Breast
In vivo magnetic resonance spectroscopy (MRS) of the breast can be used to measure the level of choline-containing compounds, which is a biomarker of malignancy. In the diagnostic setting, MRS can…
Diffusion Weighted Magnetic Resonance Imaging of the Breast
Diffusion-weighted magnetic resonance (MR) imaging (DWI) has shown promise for improving the positive predictive value of breast MR imaging for detection of breast cancer, evaluating tumor response to neoadjuvant chemotherapy,…
Radiologic-pathologic Correlation at Breast MR Imaging
Breast magnetic resonance (MR) imaging is increasingly performed for a variety of indications, most commonly with the goal of detecting breast cancer. Percutaneous biopsy (usually under MR guidance or ultrasound…
Magnetic Resonance Imaging–Guided Biopsy of the Breast
Magnetic resonance (MR) imaging is now an accepted component of standard breast-imaging practice. This article reviews the fundamentals of performing an MR imaging–guided biopsy using a grid localization system, and…
Evaluation of Breast Silicone Implants
While clinical evaluation of breast implants and their complications can identify capsule contracture and rupture of saline implants, the identification of silicone implant failure is best accomplished by silicone specific…
BI-RADS 3 for Magnetic Resonance Imaging
A BI-RADS (Breast Imaging Reporting and Data System) 3, or probably benign, assessment is given in approximately 7% to 12% of breast magnetic resonance (MR) images. However, the imaging features…
Breast Magnetic Resonance Imaging for Monitoring Response to Therapy
There is no difference in disease-free or overall survival in patients who undergo adjuvant versus neoadjuvant chemotherapy. Thus, neoadjuvant chemotherapy is recommended in patients with locally advanced breast cancer who…
Breast MR Imaging for Extent of Disease Assessment in Patients with Newly Diagnosed Breast Cancer
Breast cancer staging and surgical planning are affected by the burden of pathologically proven cancer detected on clinical examination and/or imaging. Magnetic resonance (MR) imaging has superior sensitivity and accuracy…
Breast Magnetic Resonance Imaging for Screening High-Risk Women
Mammography is the only imaging modality that has been validated by multiple randomized clinical trials and meta-analyses to reduce mortality from breast cancer. Although it is demonstrated to be effective…
Screening MR Imaging Versus Screening Ultrasound
Data support greater sensitivity of MR imaging compared with mammography and ultrasound in high-risk populations, in particular BRCA 1 and BRCA 2 carriers. Screening ultrasound improves cancer yield versus mammography…
