ABSTRACT The objective of our study was to report on the current practices of radiologists involved in the performance and interpretation of breast MRI in the United States.
We invited the 1,696 active physician members of the Society of Breast Imaging to participate in a survey addressing whether and how they performed and interpreted breast MRI. Respondents were asked to select one member of their practice to complete the survey. A total of 754 surveys were completed. Every respondent did not reply to every question.
Contrast-enhanced breast MRI was offered at 557 of 754 (73.8%) practices. Of these, 346 of 553 (62.6%) performed at least five breast MRI examinations per week, and only 56 of 553 (10.1%) performed > 20 per week. Radiologists qualified under the Mammography Quality Standards Act supervised the performance of and interpreted breast MRI in the majority of facilities. Of 552 respondents, breast MRI was interpreted as soft copy with computer-aided detection (CAD) in 280 practices (50.7%), as soft copy without CAD in 261 (47.3%), and as hard copy in 11 (2.0%). Of 551 respondents, 256 (46.5%) never and 207 (37.6%) rarely interpreted breast MRI without correlating mammography or sonography findings. The majority of respondents never (269/561, 48.0%) or rarely (165/561, 29.4%) interpreted breast MRI performed at an outside facility. Screening breast MRI was offered at 359 of 561 (64.0%) practices. Of the practices performing contrast-enhanced examinations, 173 of 557 (31.1%) did not perform MRI-guided interventional procedures.
Contrast-enhanced breast MRI is now widely used in the United States. The information gained from this survey should provide reasonable approaches for the development of professional practice guidelines.

    • "Guidelines do not provide evidence-based recommendations for how long annual mammography should be continued in women with a personal history of breast cancer—a particularly relevant issue for elderly breast cancer survivors whose life expectancies may not yield any potential benefit from early detection of breast cancer. Further, there is an absence of evidence or recommendations for surveillance use of other imaging modalities, such as ultrasound or breast MRI for surveillance, although reports demonstrate the use of these modalities for surveillance [17]. Guidelines from the American Cancer Society [18], which are endorsed by the European Society of Breast Imaging [19] and other groups, suggest MRI screening for women with a lifetime breast cancer risk ≥20% and BRCA gene mutation carriers based on evidence of value in these high-risk groups [20– 24].

    ABSTRACT: Background. Patterns of surveillance among breast cancer survivors are not well characterized and lack evidence-based practice guidelines, particularly for imaging modalities other than mammography. We characterized breast imaging and related biopsy longitudinally among breast cancer survivors in relation to women's characteristics. Methods. Using data from a state-wide (New Hampshire) breast cancer screening registry linked to Medicare claims, we examined use of mammography, ultrasound (US), magnetic resonance imaging (MRI), and biopsy among breast cancer survivors. We used generalized estimating equations (GEE) to model associations of breast surveillance with women's characteristics. Results. The proportion of women with mammography was high over the follow-up period (81.5% at 78 months), but use of US or MRI was much lower (8.0%—first follow-up window, 4.7% by 78 months). Biopsy use was consistent throughout surveillance periods (7.4%–9.4%). Surveillance was lower among older women and for those with a higher stage of diagnosis. Primary therapy was significantly associated with greater likelihood of breast surveillance. Conclusions. Breast cancer surveillance patterns for mammography, US, MRI, and related biopsy seem to be associated with age, stage, and treatment, but need a larger evidence-base for clinical recommendations.

    • "Breast MRI is also employed throughout all stages of management, from detection, diagnosis, pre-operative staging, therapy response monitoring and surveillance [2–5]. This trend is demonstrated by the nearly 40% per year increase in breast MR studies performed in the USA over the past 10 years [6]. "

    ABSTRACT: To investigate methods developed for the characterisation of the morphology and enhancement kinetic features of both mass and non-mass lesions, and to determine their diagnostic performance to differentiate between malignant and benign lesions that present as mass versus non-mass types. Quantitative analysis of morphological features and enhancement kinetic parameters of breast lesions were used to differentiate among four groups of lesions: 88 malignant (43 mass, 45 non-mass) and 28 benign (19 mass, 9 non-mass). The enhancement kinetics was measured and analysed to obtain transfer constant (K(trans)) and rate constant (k(ep)). For each mass eight shape/margin parameters and 10 enhancement texture features were obtained. For the lesions presenting as nonmass-like enhancement, only the texture parameters were obtained. An artificial neural network (ANN) was used to build the diagnostic model. For lesions presenting as mass, the four selected morphological features could reach an area under the ROC curve (AUC) of 0.87 in differentiating between malignant and benign lesions. The kinetic parameter (k(ep)) analysed from the hot spot of the tumour reached a comparable AUC of 0.88. The combined morphological and kinetic features improved the AUC to 0.93, with a sensitivity of 0.97 and a specificity of 0.80. For lesions presenting as non-mass-like enhancement, four texture features were selected by the ANN and achieved an AUC of 0.76. The kinetic parameter k(ep) from the hot spot only achieved an AUC of 0.59, with a low added diagnostic value. The results suggest that the quantitative diagnostic features can be used for developing automated breast CAD (computer-aided diagnosis) for mass lesions to achieve a high diagnostic performance, but more advanced algorithms are needed for diagnosis of lesions presenting as non-mass-like enhancement.

    ABSTRACT: Advances in dynamic contrast-enhanced (DCE) breast MRI over the past decade have led to significant improvements in the detection of early breast cancer and higher accuracy in the detection of multifocal and multicentric disease. This has resulted in the increased application of breast MRI in the diagnosis and management of breast cancer globally. Nonetheless, the true role of DCE breast MRI in the management of breast cancer patients remains controversial. This article discusses the strengths and limitations of DCE breast MRI by reviewing existing and emerging data from the past decade.
