Two national mammography quality certification programs in Brazil: Framework and main outcomes between 2017 and 2021.

Background: This study aims to provide an academic medical overview of the framework and key outcomes of two mammography quality certification programs in Brazil.

Methods: These programs assess radiation dose and phantom image quality in mammography units through a postal system. Each unit that passes this initial assessment is required to submit a sample of copies of five complete examinations.

Pre-treatment MRI tumor features and post-treatment mammographic findings: may they contribute to refining the prediction of pathologic complete response in post-neoadjuvant breast cancer patients with radiologic complete response on MRI?

Purpose: Radiologic complete response (rCR) in breast cancer patients after neoadjuvant chemotherapy (NAC) does not necessarily correlate with pathologic complete response (pCR), a marker traditionally associated with better outcomes. We sought to verify if data extracted from two important steps of the imaging workup (tumor features at pre-treatment MRI and post-treatment mammographic findings) might assist in refining the prediction of pCR in post-NAC patients showing rCR.

Methods: A total of 115 post-NAC women with rCR on MRI (2010-2016) were retrospectively assessed.

Clinical and MRI Evaluation of Silicone Gel Implants with RFID-M Traceability System: A Prospective Controlled Cohort Study Related to Safety and Image Quality in MRI Follow-Up.

Background: SmoothSilk implants (SSI) are the first generation of implants to incorporate a radio-frequency identification device (RFID-M), a non-invasive traceability system. Although the RFID-M is considered compatible with magnetic resonance imaging (MRI), the size of the artifact and its influence on breast tissue vary. This prospective study assessed safety and MRI issues in a cohort of breast reconstruction patients.

Imaging of male breast disease: the good, the bad and the ugly - A pictorial review.

The male breast is affected by a broad spectrum of conditions, ranging from benign to malignant, many of which are similar to those occurring in its female counterpart. Despite the challenge motivated by different imaging characteristic features, correct imaging interpretation in male breast disease may aid at differentiation between benign and suspected conditions, narrow the differential diagnosis and guide subsequent management. The purpose of this review is to showcase a wide array of male breast diseases, discuss their imaging presentations and key features for diagnosis.

Usefulness of Radio Frequency Identification Device in Diagnosing Rotation of Motiva SmoothSilk Implants after Augmentation Mammoplasty.

Breast implant displacement has been described as a significant risk following augmentation mammoplasty. Magnetic resonance imaging (MRI) is considered the method of choice for diagnosing implant complications, but it has its limits in assessing correct implant position and displacement. Motiva SmoothSilk/SilkSurface Implants (MSS) are the first to incorporate a radio frequency identification device (RFID), which produces an imaging artifact in MRI sequences.

Sarcomas of the breast: findings on mammography, ultrasound, and magnetic resonance imaging.

Sarcomas of the breast belong to a heterogeneous group of breast tumors of mesenchymal origin, without epithelial components. These tumors can be primary or secondary (after previous treatment for breast cancer), are rare, present aggressive behavior, and have a poor prognosis. They occur mainly in women between 45 and 50 years of age, with the exception of angiosarcomas, which can occur in younger patients.

Breast cancer screening: updated recommendations of the Brazilian College of Radiology and Diagnostic Imaging, Brazilian Breast Disease Society, and Brazilian Federation of Gynecological and Obstetrical Associations.

Objective: To present the current recommendations for breast cancer screening in Brazil, as devised by the Brazilian College of Radiology and Diagnostic Imaging, the Brazilian Breast Disease Society, and the Brazilian Federation of Gynecological and Obstetrical Associations.

Materials And Methods: We analyzed scientific studies available in the Medline and Lilacs databases. In the absence of evidence, the recommendations reflected the consensus of a panel of experts.

Axillary Lymph Node Sonographic Features and Breast Tumor Characteristics as Predictors of Malignancy: A Nomogram to Predict Risk.

The purpose of this study was to build a mathematical model to predict the probability of axillary lymph node metastasis based on the ultrasonographic features of axillary lymph nodes and the tumor characteristics. We included 74 patients (75 axillae) with invasive breast cancer who underwent axillary ultrasonography ipsilateral to the tumor and fine-needle aspiration of one selected lymph node. Lymph node pathology results from sentinel lymph node biopsy or surgical dissection were correlated with lymph node ultrasonographic data and with the cytologic findings of fine-needle aspiration.

Papillomas of the breast: factors associated with underestimation.

The distinction between benign and malignant papilloma of the breast through percutaneous needle biopsy can be difficult because of limited samples; the underestimation rate can be up to 25%. The aim of this study is to identify clinical and histological factors associated with underestimation, invasive ductal carcinoma, or ductal in-situ carcinoma (DCIS) of the breast found in surgical specimens from papillary lesions. This may contribute toward selection of patients for a follow-up strategy without the need for surgical excision.

MRI to Predict Nipple Involvement in Breast Cancer Patients.

Objective: The selection of breast cancer patients as candidates for nipple-sparing mastectomy (NSM) is dependent on the preoperative detection of neoplastic involvement of the nipple-areola complex (NAC). This cross-sectional study was designed to evaluate the accuracy of preoperative breast MRI as a noninvasive method to predict neoplastic involvement of the nipple.

Materials And Methods: We included 165 female breast cancer patients with a surgical plan that included total mastectomy or breast conservation surgery with the removal of the NAC.

Can Doppler or contrast-enhanced ultrasound analysis add diagnostically important information about the nature of breast lesions?

Objectives: Despite evidence suggesting that Doppler ultrasonography can help to differentiate between benign and malignant breast lesions, it is rarely applied in clinical practice. The aim of this study was to determine whether certain vascular features of breast masses observed by duplex Doppler and color Doppler ultrasonography (before and/or after microbubble contrast injection) add information to the gray-scale analysis and support the Breast Imaging-Reporting and Data System (BI-RADS) classification.

Methods: Seventy solid lesions were prospectively evaluated with gray-scale ultrasonography, color Doppler ultrasonography, and contrast-enhanced ultrasonography.

Mammography-based screening program: preliminary results from a first 2-year round in a Brazilian region using mobile and fixed units.

Background: Breast cancer is the most frequently diagnosed cancer and the leading cause of cancer deaths among women worldwide. The use of mobile mammography units to offer screening to women living in remote areas is a rational strategy to increase the number of women examined. This study aimed to evaluate results from the first 2 years of a government-organized mammography screening program implemented with a mobile unit (MU) and a fixed unit (FU) in a rural county in Brazil.

Gray-scale sonography of solid breast masses: diagnosis of probably benign masses and reduction of the number of biopsies.

Purpose: To identify probably benign breast masses using gray-scale sonography and to see if this strategy could reduce the number of biopsies of breast masses.

Methods: This retrospective study included 229 masses in 203 women who underwent sonographically guided percutaneous biopsy. Masses with a negative predictive value for malignancy >98% were retrospectively considered probably benign, and the potential impact of gray-scale sonography in reducing the number of biopsies if these masses were not biopsied was assessed.

Fat necrosis of the breast: mammographic, sonographic, computed tomography, and magnetic resonance imaging findings.

Fat necrosis of the breast is a benign inflammatory process that may be mistaken for cancer in clinical examination or imaging studies. Although its mammographic manifestations are well known, data from other imaging modes, particularly sonography and magnetic resonance imaging, are limited. With the growing number of breast surgeries performed today (eg, breast-conserving, autologous tissue reconstruction, mammoplasty), fat necrosis is seen more often in daily practice.
