Summary
Mammographic screening coverage in Brazil is low and uneven, with many states showing inconclusive mammogram results. Addressing these disparities is vital for early breast cancer detection.
Area of Science:
- Public Health
- Oncology
- Radiology
Background:
- Breast cancer is a leading cause of cancer death in Brazilian women.
- Understanding regional disparities in mammographic screening is crucial for early detection.
Purpose of the Study:
- Analyze mammographic screening coverage across Brazilian states.
- Evaluate the proportion of BI-RADS 0 (inconclusive) results.
Main Methods:
- Cross-sectional study using 2022 Unified Health System (SUS) data.
- Analyzed mammographic screening coverage and BI-RADS 0 rates for women aged 50-69 without private insurance.
- Examined mammography device distribution and radiologist concentration.
Main Results:
- Low national mammographic screening coverage (1.3%–15.9%) observed.
- High proportion of BI-RADS 0 results in 44% of states.
- Coverage remains low despite uneven device distribution, indicating accessibility and education barriers.
Conclusions:
- Mammographic screening coverage in Brazil is insufficient and inequitably distributed.
- High rates of inconclusive mammograms (BI-RADS 0) signal quality concerns.
- Addressing disparities is critical for effective breast cancer early detection.

2.0K
Secondary healthcare is offered by a specialist, generally in hospitals or clinics for patients referred by primary healthcare providers. It occurs when a person has an illness or injury that requires specific medical care. Secondary care is often referred to as acute care. Secondary care can range from uncomplicated care to repair a minor laceration or treat a strep throat infection to more complicated emergent care, such as treating a head injury sustained in an automobile accident.

Introduction:Magnetic Resonance Imaging, or MRI, can include a specialized imaging technique of the urinary system known as Magnetic Resonance Urography (MRU). This radiation-free technique uses strong magnetic fields and radio waves to produce detailed images with the help of a computer. MRU is particularly effective for visualizing fluid-filled structures like the kidneys, ureters, and bladder.Applications of MRI in the Genitourinary SystemKidneys and Ureters: MRI detects tumors, cysts,...

Preventive healthcare services keep people healthy via frequent check-ups, screening, and counseling. They primarily aid in disease prevention rather than treating an acute or chronic illness. Preventive treatment also keeps individuals productive and energetic, allowing them to work well into their retirement years. Examples of preventive care services include:

Description
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...
