Summary
Personal history of breast cancer strongly influences breast MRI use. However, factors like race and perceived risk also play a role, questioning current practice guidelines for this controversial imaging technique.
Area of Science:
- Radiology and Imaging
- Oncology
- Public Health
Background:
- Breast magnetic resonance imaging (MRI) use is widespread despite ongoing controversy.
- Understanding the drivers of breast MRI utilization is crucial for evidence-based practice.
Purpose of the Study:
- To identify factors influencing breast MRI use in a representative US population.
- To examine the association between sociodemographic, risk characteristics, and breast MRI utilization.
Main Methods:
- Analysis of 2010 National Health Interview Survey data from 11,222 women aged 30 years and older.
- Inclusion of sociodemographic, personal/family history of breast cancer, benign biopsy history, perceived risk, and insurance status.
Main Results:
- 4.7% of women reported ever having a breast MRI; 25% were for routine exams.
- Multivariate analysis showed African-American race, personal history of breast cancer, benign biopsy history, and high perceived risk were associated with increased MRI use.
- In women without a personal history of breast cancer, race, benign biopsy history, and perceived risk remained significant correlates, while family history did not.
Conclusions:
- Personal history of breast cancer is the primary driver of breast MRI use.
- Race, benign biopsy history, and perceived risk are independently associated with MRI use, but family history is not.
- Current breast MRI practice patterns may not align with evidence-based guidelines, necessitating further review.

01:24Magnetic Resonance Imaging
Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...
01:27Imaging Studies IV: Magnetic Resonance Imaging
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,...
01:21Imaging Studies for Cardiovascular System IV: CMRI
Cardiovascular magnetic resonance imaging, or CMRI, is a non-invasive diagnostic test that employs a magnetic field and radiofrequency waves to create precise images of the heart and arteries. It provides comprehensive information about cardiac anatomy, function, perfusion, and tissue characterization without ionizing radiation.IndicationsCMRI diagnoses various heart conditions, including tissue damage from heart attacks, ischemic heart disease, myocarditis, aortic issues (tears, aneurysms,...

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...
