Pilot Educational Intervention and Feasibility Assessment of Breast Ultrasound in Rural South Africa
Purpose Breast cancer is the leading cause of cancer death in women worldwide, with high mortality in low- and middle-income countries because of a lack of detection, diagnosis, and treatment. With mammography unavailable, ultrasound offers an alternative for downstaging. The literature reports successful training in various domains, but a focus on the breast is novel. We assessed the feasibili...
The imaging evaluation of the augmented breast is becoming more and more frequent in daily practice. Even if mammography remains the golden standard for breast cancer screening, ultrasound is used as a first step investigation in young symptomatic patients or as a screening tool in detecting pathology related to the implants. This pictorial essay reviews the indications and limitations of the i...
BACKGROUND Ultrasound-guided diagnostic breast biopsy technology represents the current standard of care for the evaluation of indeterminate and suspicious lesions seen on diagnostic breast ultrasound. Yet, there remains much debate as to which particular method of ultrasound-guided diagnostic breast biopsy provides the most accurate and optimal diagnostic information. The aim of the current st...
BACKGROUND: The axillary lymph node status is one of the most relevant prognostic factors in breast cancer. The noninvasive investigation of axillary lymph node involvement in the preoperative diagnosis is one of the greatest challenges in the treatment of breast cancer. The aim of our study is to assess the significance of preoperative axillary diagnostics. It will be verified whether the axil...
Ultrasound has long been an efficient and useful adjunct technique for breast imaging. It is the first modality to be proposed in some situations: if a young or pregnant woman has a palpable mass, for example, or immediately after surgery. Ultrasound is usually performed during the diagnostic workup of masses, if architectural distortion is detected on mammograms, or following mammographic scre...
rhabdomyosarcoma is a common primary childhood malignancy that rarely metastasizes to the breast. we report a patient with a primary sinonasal rhabdomyosarcoma metastasizing to the breast, with no distant spread. we describe the imaging appearance of rhabdomyosarcoma on magnetic resonance imaging (mri), particularly on diffusion-weighted imaging (dwi) and apparent diffusion coefficient (adc) se...
Background/aim: To evaluate the diagnostic performance of strain elastography (SE) combined with B-mode ultrasound in distinguishing between idiopathic granulomatous mastitis (IGM) and malignant breast lesions. Materials and methods: Seventy-seven malignant breast lesions and 36 IGM were assessed using B-mode ultrasound and SE. Ultrasonographic findings for all the breast lesions were classifie...
Background: Acoustic cavitation which occurs at high intensities of ultrasound waves can be fatal for tumor cells; however, it can be used to destroy cancer cells as an efficient therapeutic method. On the other hand, it is known that the existence of nanoparticles in a liquid decreases the acoustic cavitation onset threshold. Materials and Methods: In this work, the combined effects of therape...
Computer-aided Diagnosis (CADx) based on explainable artificial intelligence (XAI) can gain the trust of radiologists and effectively improve diagnosis accuracy consultation efficiency. This paper proposes BI-RADS-Net-V2, a novel machine learning approach for fully automatic breast cancer in ultrasound images. The BI-RADS-Net-V2 accurately distinguish malignant tumors from benign ones provides ...
To investigate the diagnostic value of breast ultrasound breast imaging reporting and data system (BIRADS) classification combined with transforming growth factor-β (TGF-β) detection to differentiate malignant from benign tumors. This study enrolled 163 patients with breast tumor (breast cancer of 104 cases and breast benign tumor of 59 cases) who were admitted to Cangzhou Central Hospital from...
