When breast cancer is detected and treated early, the chances of survival are very high. However, women in many settings face complex barriers to early detection, including social, economic, geographic, other interrelated factors, which can limit their access timely, affordable, effective health care services. Previously, Breast Health Global Initiative (BHGI) developed resource‐stratified guidelines for detection diagnosis cancer. In this consensus article from sixth BHGI Summit held...

Purpose To investigate whether qualitative magnetic resonance (MR) imaging assessments of background parenchymal enhancement (BPE), amount fibroglandular tissue (FGT), and mammographic density are associated with risk developing breast cancer in women who at high risk. Materials Methods In this institutional review board–approved HIPAA-compliant retrospective study, all screening MR images obtained from January 2006 to December 2011 aged 18 years or older for but without a history were...

Hypoxia-inducible factor-1α (HIF-1α) plays an essential role in cellular and systemic O 2 homeostasis by regulating the expression of genes important glycolysis, erythropoiesis, angiogenesis, catecholamine metabolism. It is also believed to be a key component response hypoxia ischemia under pathophysiological conditions, such as stroke. To clarify function HIF-1α brain, we exposed adult mice with late-stage brain deletion hypoxic injuries. Contrary expectations, brains from HIF-1 α-deficient...

Abstract Platforms that allow parallel, quantitative analysis of single cells will be integral to realizing the potential postgenomic biology. In stem cell biology, study clonal in multiwell formats is currently both inefficient and time‐consuming. Thus, investigate low‐frequency events interest, large sample sizes must interrogated. We report a simple, versatile, efficient micropatterned arraying system conducive culture dynamic monitoring proliferation. This platform enables: 1) automated,...

The objective of our study was to determine the accuracy preoperative measurements for detecting pathologic complete response (CR) and assessing residual disease after neoadjuvant chemotherapy (NACT) in patients with locally advanced breast cancer. American College Radiology Imaging Network 6657 Trial prospectively enrolled women ≥ 3 cm invasive cancer receiving NACT. Preoperative included longest diameter by mammography, MRI, clinical examination functional volume on MRI. CR association...

Since the introduction of MRI as a sustainable diagnostic modality, global accessibility to its services has revealed wide discrepancy between populations-leaving most population in LMICs without access this important imaging modality. Several factors lead scarcity LMICs; for example, inadequate infrastructure and absence dedicated workforce are key observed. RAD-AID contributed advancement radiology globally by collaborating with our partners make more accessible medically underserved...

Background Contrast-enhanced mammography (CEM) and abbreviated breast MRI (ABMRI) are emerging alternatives to standard for supplemental cancer screening. Purpose To compare the diagnostic performance of CEM, ABMRI, MRI. Materials Methods This single-institution, prospective, blinded reader study included female participants referred from January 2018 June 2021. CEM was performed within 14 days MRI; ABMRI produced images. Two readers independently interpreted each after a washout period....
