Nipple-sparing Mastectomy: What the Radiologist Should Know.

Nipple-sparing mastectomy (NSM) is increasingly offered to patients undergoing treatment of breast cancer and prophylaxis treatment for reduction of breast cancer risk. NSM is considered oncologically safe for appropriately selected patients and is associated with improved cosmetic outcomes and quality of life. Accepted indications for NSM have expanded in recent years, and currently only inflammatory breast cancer or malignancy involving the nipple is considered an absolute contraindication. Neoplasms close to and involving the nipple areolar complex are common, and cancer of the lactiferous ducts can spread to the nipple. Therefore, accurate determination of nipple involvement at imaging examinations is critical to identifying appropriate candidates for NSM and preventing local recurrence. Multiple imaging features have been described as predictors of nipple involvement, with tumor to nipple distance, enhancement between the index malignancy and the nipple, and nipple retraction demonstrating the highest predictive values. These features can be assessed at multimodality breast imaging, particularly at breast MRI, which demonstrates high specificity and negative predictive value for determining nipple involvement in malignancy.

Patient Notification About Breast Arterial Calcification on Mammography: Empowering Women With Information About Cardiovascular Risk.

OBJECTIVE: To assess the impact of informing women about the presence of breast arterial calcification (BAC) on mammography by determining whether those notified about the presence of BAC would seek cardiovascular evaluation. METHODS: This IRB-approved prospective study included 494 patients who underwent screening mammography between June 8, 2021, and April 22, 2022. Mammograms were reviewed by a radiologist, and patients were notified via e-mail about the presence or absence of BAC. Patients with BAC were advised to discuss the results with their physicians and were surveyed 3 months later. Frequencies and proportions were calculated for study participation, presence of BAC, survey participation, health actions, and perceptions. Confidence intervals were calculated for proportions of health actions and perceptions. RESULTS: Of 494 study participants, 68/494 (13.8%; 95% CI: 10.9%-17.1%) had BAC detected on mammography and 42/68 (61.8%; 95% CI: 61.1%-62.1%) with BAC completed the follow-up survey at 3 months. Of these 42 survey respondents, 24/42 (57.1%; 95% CI: 41.1%-72.3%) reported discussing results with their primary care physician (PCP) or a cardiologist. In addition, 34/42 (81.0%; 95% CI: 65.9%-91.4%) reported finding it helpful to receive information about BAC and 32/42 (76.2%; 95% CI: 60.6%-88.0%) believed all women should be informed about BAC after mammography. CONCLUSION: After notification about the presence of BAC on screening mammography, the majority (57.1%) of survey respondents reported discussing the results with a PCP or cardiologist. These results suggest that providing mammography patients with information about BAC may promote preventive cardiovascular health.

The patient-friendly radiology report: history, evolution, challenges and opportunities.

The past several decades have witnessed dramatic developments and improvements in the field of radiology, including technologic innovations and new imaging modalities, picture archiving and communication systems, and the rise of artificial intelligence. At the same time, an evolution has been occurring in a fundamental component of radiology practice - the radiologist's report. Initially, the radiology report was a private written communication between the radiologist and the referring physician 1,2. Today, the report is an electronic document, displayed on web portals, and visible to both physicians and the patients themselves.3 A provision in the 21st Century Cures Act, signed into law on December 13, 2016, ensures that radiology reports in the electronic health record are visible to patients without delay 4. To meet modern patient expectations and legal requirements, the structure and purpose of the radiologist report is changing. This article will provide an overview of the history of radiology reporting and the law, discuss the role of the radiologist report within the context of patient and family centered care, review current strategies and investigations in patient-friendly reporting, and summarize radiology reporting challenges and opportunities for the future.

ACR Appropriateness Criteria® Supplemental Breast Cancer Screening Based on Breast Density.

Mammography remains the only validated screening tool for breast cancer, however, there are limitations to mammography. One of the limitations of mammography is the variable sensitivity based on breast density. Supplemental screening may be considered based on the patient's risk level and breast density. For average-risk women with nondense breasts, the sensitivity of digital breast tomosynthesis (DBT) screening is high; additional supplemental screening is not warranted in this population. For average-risk women with dense breasts, given the decreased sensitivity of mammography/DBT, this population may benefit from additional supplemental screening with contrast-enhanced mammography, screening ultrasound (US), breast MRI, or abbreviated breast MRI. In intermediate-risk women, there is emerging evidence suggesting that women in this population may benefit from breast MRI or abbreviated breast MRI. In intermediate-risk women with dense breasts, given the decreased sensitivity of mammography/DBT, this population may benefit from additional supplemental screening with contrast-enhancedmammography or screening US. There is strong evidence supporting screening high-risk women with breast MRI regardless of breast density. Contrast-enhanced mammography, whole breast screening US, or abbreviated breast MRI may be also considered. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision include an extensive analysis of current medical literature from peer reviewed journals and the application of well-established methodologies (RAND/UCLA Appropriateness Method and Grading of Recommendations Assessment, Development, and Evaluation or GRADE) to rate the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where evidence is lacking or equivocal, expert opinion may supplement the available evidence to recommend imaging or treatment.

ACR Appropriateness Criteria® Stage I Breast Cancer: Initial Workup and Surveillance for Local Recurrence and Distant Metastases in Asymptomatic Women.

As the proportion of women diagnosed with early stage breast cancer increases, the role of imaging for staging and surveillance purposes is considered. National and international guidelines discourage the use of staging imaging for asymptomatic patients newly diagnosed with stage 0 to II breast cancer, even if there is nodal involvement, as unnecessary imaging can delay care and affect outcomes. In asymptomatic patients with a history of stage I breast cancer that received treatment for curative intent, there is no role for imaging to screen for distant recurrences. However, routine surveillance with an annual mammogram is the only imaging test that should be performed to detect an in-breast recurrence or a new primary breast cancer in women with a history of stage I breast cancer. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision include an extensive analysis of current medical literature from peer reviewed journals and the application of well-established methodologies (RAND/UCLA Appropriateness Method and Grading of Recommendations Assessment, Development, and Evaluation or GRADE) to rate the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where evidence is lacking or equivocal, expert opinion may supplement the available evidence to recommend imaging or treatment.

ACR Appropriateness Criteria® Breast Pain.

Breast pain is a common complaint. However, in the absence any accompanying suspicious clinical finding (eg, lump or nipple discharge), the association with malignancy is very low (0%-3.0%). When malignancy-related, breast pain tends to be focal (less than one quadrant) and persistent. Pain that is clinically insignificant (nonfocal [greater than one quadrant], diffuse, or cyclical) requires no imaging beyond what is recommended for screening. In cases of pain that is clinically significant (focal and noncyclical), imaging with mammography, digital breast tomosynthesis (DBT), and ultrasound are appropriate, depending on the patient's age. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision include an extensive analysis of current medical literature from peer reviewed journals and the application of well-established methodologies (RAND/UCLA Appropriateness Method and Grading of Recommendations Assessment, Development, and Evaluation or GRADE) to rate the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where evidence is lacking or equivocal, expert opinion may supplement the available evidence to recommend imaging or treatment.

ACR Appropriateness Criteria® Breast Imaging of Pregnant and Lactating Women.

Breast imaging during pregnancy and lactation is challenging due to unique physiologic and structural breast changes that increase the difficulty of clinical and radiological evaluation. Pregnancy-associated breast cancer (PABC) is increasing as more women delay child bearing into the fourth decade of life, and imaging of clinical symptoms should not be delayed. PABC may present as a palpable lump, nipple discharge, diffuse breast enlargement, focal pain, or milk rejection. Breast imaging during lactation is very similar to breast imaging in women who are not breast feeding. However, breast imaging during pregnancy is modified to balance both maternal and fetal well-being; and there is a limited role for advanced breast imaging techniques in pregnant women. Mammography is safe during pregnancy and breast cancer screening should be tailored to patient age and breast cancer risk. Diagnostic breast imaging during pregnancy should be obtained to evaluate clinical symptoms and for loco-regional staging of newly diagnosed PABC. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision include an extensive analysis of current medical literature from peer reviewed journals and the application of well-established methodologies (RAND/UCLA Appropriateness Method and Grading of Recommendations Assessment, Development, and Evaluation or GRADE) to rate the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where evidence is lacking or equivocal, expert opinion may supplement the available evidence to recommend imaging or treatment.

ACR Appropriateness Criteria® Breast Implant Evaluation.

Breast implant imaging varies depending on patient age, implant type, and symptoms. For asymptomatic patients (any age, any implant), imaging is not recommended. Rupture of saline implants is often clinically evident, as the saline is resorbed and there is a change in breast contour. With saline implants and equivocal clinical findings, ultrasound (US) is the examination of choice for patients less than 30 years of age, either mammography/digital breast tomosynthesis or US may be used for those 30 to 39 years of age, and mammography/digital breast tomosynthesis is used for those 40 years and older. For patients with suspected silicone implant complication, MRI without contrast or US is used for those less than 30 years of age; MRI without contrast, mammography/digital breast tomosynthesis, or US may be used for those 30 to 39 years of age; and MRI without contrast or mammography/digital breast tomosynthesis is used for those 40 years and older. Patients with unexplained axillary adenopathy and silicone implants (current or prior) are evaluated with axillary US. For patients 30 years and older, mammography/digital breast tomosynthesis is performed in conjunction with US. Last, patients with suspected breast implant-associated anaplastic large-cell lymphoma are first evaluated with US, regardless of age or implant type. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision include an extensive analysis of current medical literature from peer reviewed journals and the application of well-established methodologies (RAND/UCLA Appropriateness Method and Grading of Recommendations Assessment, Development, and Evaluation or GRADE) to rate the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where evidence is lacking or equivocal, expert opinion may supplement the available evidence to recommend imaging or treatment.

ACR Appropriateness Criteria® Evaluation of the Symptomatic Male Breast.

Although the majority of male breast problems are benign with gynecomastia as the most common etiology, men with breast symptoms and their referring providers are typically concerned about whether or not it is due to breast cancer. If the differentiation between benign disease and breast cancer cannot be made on the basis of clinical findings, or if the clinical presentation is suspicious, imaging is indicated. The panel recommends the following approach to breast imaging in symptomatic men. In men with clinical findings consistent with gynecomastia or pseudogynecomastia, no imaging is routinely recommended. If an indeterminate breast mass is identified, the initial recommended imaging study is ultrasound in men younger than age 25, and mammography or digital breast tomosynthesis in men age 25 and older. If physical examination is suspicious for a male breast cancer, mammography or digital breast tomosynthesis is recommended irrespective of patient age. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision include an extensive analysis of current medical literature from peer reviewed journals and the application of well-established methodologies (RAND/UCLA Appropriateness Method and Grading of Recommendations Assessment, Development, and Evaluation or GRADE) to rate the appropriateness of imaging and treatment procedures for specific clinical scenarios.
