Breast Imaging

Breast imaging is a subspecialty within diagnostic radiology devoted to the diagnosis and treatment of breast diseases. Whether with magnetic resonance imaging or with nuclear medicine or with mammograms and scans using other imaging modalities, breast imaging is a vital medical diagnostic protocol. Oakstone Publishing, LLC is your authoritative source for clinical breast imaging courses and breast imaging CME (continuing medical education).

Features from this Topic

Knowing patients’ risk profiles can make radiologists’ readings of screening mammograms more accurate—depending on whether the profile information is given the proper weight and delivered at the proper time.

That’s the conclusion of research presented at a conference last week by Mehmet U. S. Ayvaci, PhD, assistant professor of information systems and operations management at the Naveen Jindal School of Management at … read more »

Is a 28 percent reduced risk of death from breast cancer enough?

That was the question debated last week in the virtual pages of BMJ. A Norwegian study published online June 17 looked at all Norwegian women age 50 to 79 years between 1986 and 2009. During that period, Norway gradually introduced mammography screening for breast cancer. The researchers found the following:
Based … read more »

An international team of researchers has found a way to make iron oxide nanoparticles behave usefully for both MRI imaging and treatment of tumors: encase them inside larger silicon and polymer particles.

That creates versatile iron oxide composites that can act as MRI contrast agents, be manipulated with magnets, be heated, and degrade quickly. Normally, you would need different sizes of … read more »

A breakthrough at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory in Berkeley, California, could lead to high-frequency ultrasound imaging with up to 1,000 times higher resolution than today’s medical ultrasounds.

Xiang Zhang, PhD, summed up the research this way:
We have demonstrated optical coherent manipulation and detection of the acoustic phonons in nanostructures that offer new possibilities in the development … read more »

Between 1979, before screening mammography became widespread, and 2009, according to a new study led by the University of Michigan Comprehensive Cancer Center, late-stage breast cancer in the United States has decreased by somewhere around 37 percent.

The researchers took into account a general increase in breast cancer cases that has been observed worldwide, even in countries that have no routine … read more »

Computer simulations indicate that, for the most part, new gamma and neutron imaging techniques would be safe, delivering roughly the same radiation dosages as X-rays or CT scans—at least while imaging the liver or breast.

Researchers at Duke Medicine in Durham, North Carolina, came to that conclusion. And the new techniques offer advantages, said Anuj J. Kapadia, PhD, assistant professor of … read more »

MRI use substantially improves breast cancer screening for female survivors of childhood Hodgkin’s lymphoma (HL), according to a Canadian-led study detailed in an article published online today in Cancer.

Women who underwent chest radiation therapy for Hodgkin’s lymphoma have an increased risk of breast cancer. Established guidelines recommend MRI breast screening starting at age 25 or eight years after the chest radiation, … read more »

University of Michigan researchers may finally have figured out how to use terahertz rays for imaging—by converting them into ultrasound.

The terahertz band lies between microwaves and infrared light on the electromagnetic spectrum. (From left to right, longer to shorter wavelengths, the spectrum is radio waves, microwaves, terahertz waves, infrared waves, visible light waves, ultraviolet waves, X-rays, and gamma rays.) We’ve … read more »

A few hurdles remain, but phase contrast X-ray imaging shows promise for creating breast images of much greater detail than current mammographic methods, according to Swiss researchers.

An article published last week in Nature Communications details their latest findings. They report that their technique allowed classification of breast microcalcifications with 100 percent sensitivity and specificity when using phantoms. Microcalcifications are often associated … read more »

If everything goes right, a new radioisotope plant will open in Columbia, Missouri, right about the time North America’s major source of radioisotopes is scheduled to shut down for good.

Last week, Northwest Medical Isotopes of Corvallis, Oregon, announced plans to open a $50 million facility to produce molybdenum-99 at the University of Missouri’s Discovery Ridge Research Park in Columbia. That … read more »
