Correct identification of nonmalignant lesions at MR imaging could direct the patient toward imaging follow-up rather than surgical excision, thereby reducing both patient anxiety and costs related to the surgical procedure as well as avoiding surgical scarring--which potentially could alter the interpretation of subsequent imaging studies

Intrinsic susceptibility-weighted MR imaging has the ability to provide information about blood volume in patients with primary breast cancer; it may also provide a means with which to evaluate changes in tumor oxygenation in response to chemotherapy

Axillary US is a valuable modality for evaluating the preoperative status of the axilla and provides a noninvasive means with which to accurately exclude advanced axillary metastatic disease for 96% of patients with invasive ductal carcinoma

The time added to radiologists' interpretations of screening mammograms by the use of computer-aided detection is an important consideration in the assessment of the efficiency of digital mammography interpretation

The additional time required to review CAD images represented a 19% increase in the mean interpretation time without CAD.

CAD requires a considerable time investment for digital screening mammography but may provide less measurable benefits in terms of confidence of the radiologists

A quantitative dynamic contrast-enhanced MR imaging method has been developed to assess treatment response to neoadjuvant chemotherapy in patients with breast cancer by using standard clinical dynamic contrast-enhanced MR imaging data without measuring either arterial input function or baseline T1.

Results of the simulation study demonstrate that the T1-FCM method appears to be relatively insensitive to noisy dynamic contrast-enhanced MR imaging data. This method could prove useful in the evaluation of breast cancer therapy

Our results show that in patients with breast cancer, the pretreatment apparent diffusion coefficients of patients who responded to neoadjuvant chemotherapy are significantly lower than those of patients who did not respond to neoadjuvant chemotherapy.

Patients with breast cancer and a low pretreatment ADC tended to respond better to chemotherapy. Prediction of response to neoadjuvant chemotherapy with DW MR imaging might help physicians individualize treatments and avoid ineffective chemotherapy

Short-term Follow-up Recommendations after Preoperative Breast MR Assessment for Breast Cancer Diagnosis: Are We Lacking a Rational Basis?

Short-term Follow-up Recommendations after Preoperative Breast MR Assessment for Breast Cancer Diagnosis: Are We Lacking a Rational Basis?

Unless clinical studies demonstrate previously unrecognized changes on serial MR imaging studies under such circumstances which likely are not based on the mechanisms of actions described earlier, the recommendation for short-term follow-up MR imaging after preoperative assessment should be reconsidered
